Using Photoshop to help find missing kids

A few years ago, John Penn was invited to attend the Internet Crimes Against Children Conference and share his knowledge as a Photoshop engineer. The experience changed his life. Now he’s a Senior Solutions Architect helping law enforcement agencies around the world use Photoshop to combat the exploitation of children.

The World’s Smallest Movie

WTF, IBM, GTFO…

I remember in the early 80’s “drawing” on an IBM PCjr, fastidiously pecking out pixel after pixel. Now the company behind that artistic juggernaut has taken that approach to an insane extreme:

You’re about to see the movie that holds the Guinness World Records™ record for the World’s Smallest Stop-Motion Film. The ability to move single atoms — the smallest particles of any element in the universe — is crucial to IBM’s research in the field of atomic memory. But even nanophysicists need to have a little fun. In that spirit, IBM researchers used a scanning tunneling microscope to move thousands of carbon monoxide molecules (two atoms stacked on top of each other), all in pursuit of making a movie so small it can be seen only when you magnify it 100 million times. A movie made with atoms.

The making-of is fascinating:

Presumably, notes Adobe video PM Al Mooney, it was edited in Premiere Proton. ;-)

A new Photoshop extension detects image manipulation

I’m excited to announce that the company founded by my old boss & friend Kevin Connor, working together with image authenticity pioneer Dr. Hany Farid, has released their first product, FourMatch—an extension for Photoshop CS5/CS6 that “instantly distinguishes unmodified digital camera files from those that may have been edited.” From the press release:

FourMatch… appears as a floating panel that automatically and instantly provides an assessment of any open JPEG image. A green light in the panel indicates that the file matches a verified original signature in FourMatch software’s extensive and growing database of more than 70,000 signatures. If a match is not found, the panel displays any relevant information that can aid the investigator in further assessing the photo’s reliability.

Check it out in action, and see also coverage in the NY Times:

One other neat detail:

Fourandsix will donate 2 percent of their proceeds from the sale of this software to the National Center for Missing & Exploited Children (NCMEC). The donation will support NCMEC efforts to find missing children and prevent the abduction and sexual exploitation of children.

Insane in the literal membrane

The crazy nerds at Backyard Brains have created “the world’s first cephalo-iPod,” pumping Cypress Hill through the body of an unsuspecting squid:

An iPod plays music by converting digital music to a small current that it sends to tiny magnets in the earbuds. The magnets are connected to cones that vibrate and produce sound.

Since this is the same electrical current that neurons use to communicate, we cut off the ear buds and instead placed the wire into the fin nerve. When the iPod sends bass frequencies (<100Hz) the axons in the nerves have enough charge to fire an action potential. This will in turn cause the muscles in the chromatophores to contract.

Adobe & MIT team up on Halide, a new imaging language

Last month I broke the somewhat sad news that Adobe’s Pixel Bender language is being retired, but for a good cause: we can now redirect effort & try other ways to achieve similar goals. To that end, Adobe researchers have teamed up with staff at the Massachusetts Institute of Technology to define Halide, a new programming language for imaging. It promises faster, more compact, and more portable code.

According to MIT News,

In tests, the MIT researchers used Halide to rewrite several common image-processing algorithms whose performance had already been optimized by seasoned programmers. The Halide versions were typically about one-third as long but offered significant performance gains — two-, three-, or even six-fold speedups. In one instance, the Halide program was actually longer than the original — but the speedup was 70-fold.

Hot damn. #progress

Or, as my Photoshop-centric brain saw it, “He’s moving two overlapping paths with a Boolean operation & red stroke/inner shadow layer style applied.” Because, yes, I need to get out a lot more.

“Photoshopped or Not? A Tool to Tell”

My longtime boss Kevin Connor left Adobe earlier this year to launch a startup, Fourandsix, aimed at “revealing the truth behind every photograph.” Now his co-founder (and Adobe collaborator) Hany Farid has published some interesting research:

Dr. Farid and Eric Kee, a Ph.D. student in computer science at Dartmouth, are proposing a software tool for measuring how much fashion and beauty photos have been altered, a 1-to-5 scale that distinguishes the infinitesimal from the fantastic. Their research is being published this week in a scholarly journal, The Proceedings of the National Academy of Sciences.

Exhibit: Photo Tampering Throughout History

You can build a business manipulating photos; how about building one by detecting those manipulations?

My longtime boss Kevin Connor was instrumental in building Photoshop, Lightroom, and PS Elements into the successes they are today, and he taught me the ropes of product management. After 15 years he was ready to try starting his own company, so this spring he teamed up with Dr. Hany Farid (“the father of digital image forensics,” said NOVA). Together they’ve started forensics company Fourandsix (get the pun?), aimed at “revealing the truth behind every photograph.”

Now they’ve put up Photo Tampering Throughout History, an interesting collection of famous (and infamous) forgeries & manipulations from Abraham Lincoln’s day to the present. Numerous examples include before & after images plus brief histories of what happened.

I wish Kevin & Hany great success in this new endeavor, and I can’t wait to see the tools & services they introduce.

Astronomical distances

Happy 50th anniversary of human space flight!. Healing Brush creator Todor Georgiev, noting that April 12 is World Cosmonautics Day, somewhat ruefully observes:

If 50 years ago we had a state-of-the-art spaceship, and if we launched a flight to the nearest star (at the same time as Gagarin’s flight), where would we be now? Already there and back, right? No. Or maybe halfway there? No! The answer is: We would have travelled 0.03% of the way. I just did the math. It would take us 150,000 years to get there. And I am not counting the costs.

Lest that get you down, here’s NASA astronaut Cady Coleman and Jethro Tull founder Ian Anderson in an earth/space flute duet playing homage to Yuri Gagarin. (Also, you might like Chopping Block’s Above Earth t-shirt, commemorating 23 historic flights. The little chimp & dog silhouettes make it for me.)

From great heights: Cool weather balloon + camera project

Colin Rich used a homemade weather balloon to carry cameras to an altitude of 125,000 feet:

According to PetaPixel,

After purchasing two Canon compact cameras on eBay, Rich programmed them to take 3 photos every 3 minutes, and shoot a minute of video every fourth minute. The cameras were then insulated in styrofoam, and sent up to 125,000 feet before the balloon burst. With the help of a parachute, the cameras descended for 35 minutes and landed about 15-20 miles away.

It’s a great time to be alive. [Via]

It reminds me of a more automated version of the Video Trace technology (see demo) that popped up around two years ago. It also brings to mind Strata’s Foto 3D, a tool for generating 3D models from within Photoshop using just a series of photographs.
I know Photoshop’s entry into 3D can sometimes be a little confusing (e.g. wasn’t the app big/complex enough already?), but we see 3D becoming more and more accessible & ubiquitous. It’s not a question of “if” but “when.” For more info you may want to see “Photoshop 3D is not about 3D.”

Counting chickens in Africa, via Photoshop

A few years ago I heard from a researcher at DuPont who was, as I recall, using Photoshop’s Histogram palette & other tools to analyze samples of Kevlar and other materials.  Later I visited the Johnson Space Flight Center and talked to a team about using Photoshop’s Ruler Tool to assess possible cracks in space shuttle heat shields photographed during flight.  No matter what you think a given feature is designed to do, customers will always find interesting ways to push it farther.

 

In that vein, Chris Ing gets crafty on JacksofScience.com, using the new analysis tools in PS CS3 Extended to do everything from estimating chicken density in Africa* (by analyzing the "integrated density" of various regions of an info graphic) to calculating the height of Kirsten Dunst (studiously cross-checked against something called Chickipedia–and no, I’m not feigning ignorance).  Should you find yourself "interested in comparing the circularity of your head to that of a friend," you’ve got a kindred spirit.

* Sorry, the pre-/post-hatched counting enhancement will have to wait for a future release. (We’ll sic Chris on it.) We’ve heard somewhere that it’s an important distinction…

Adobe puts 3D insect eyes on your camera

“Why,” I wondered for a long time, “is a wild-haired Eastern European guy walking around our floor carrying a medium-format camera & a hot glue gun?”  The answer, I discovered, is that Adobe research scientist Todor Georgiev* has been working on algorithms for use with a plenoptic camera & was motivated to build his own lenticular lens array.

So, what does any of that mean?  The goal is to let cameras capture a moment in time from multiple slightly different perspectives.  The resulting image (a series of smaller images, actually) might then enable the photographer to change the focal distance of the photo after the fact, or to use depth information to aid in selecting & editing objects.

News.com has more info & images, and I think the potential comes through best in Audioblog.fr’s video of Adobe VP Dave Story showing off the lens.  Gizmodo writes, “It’s a way-cool demo, but it might be a while before you see such a fancy lens on everyday cameras. But a focus brush in Photoshop? Whoa. Sign us up.” [Via Cari Gushiken]

*Okay, his hair seems to be less wild these days, but Todor still kicks out “light reading” like this (PDF). I think I left my copy at the beach.

World’s first terapixel image, online via Flash

Medical imaging company Aperio has created what it’s calling "the world’s first terapixel image"–i.e. an image containing more than one trillion pixels. The image itself, depicting a breast cancer scan*, is a 1,095,630 x 939,495 pixel whopper that tips the scales at 2875.94GB.  More info is in the press release.

From a Photoshop/Adobe perspective, it’s cool to see this image displayed via the Flash Player, using the same Zoomify technology that’s in Photoshop CS3.  The folks at Aperio write,

You may be interested to know Aperio has implemented BigTIFF – support for TIFF files larger than 4GB.  After linking the new version of libtiff into our ImageServer, we were able to use the Zoomify viewer with no changes at all.  Pretty impressive. By way of demonstration we’ve made the world’s first terapixel image, and it can be viewed right in a standard web browser with the Zoomify technology."

[For more Zoomify hugeness, check out the 8.6 gigapixel fresco mentioned previously.]

*Not the most asethetically compelling image–unless, I suppose, it proves that one doesn’t have breast cancer

Digital imaging goes to court

CNET reported recently on a court case that involved image authentication software as well as human experts, both seeking to distinguish unretouched photographs from those created or altered using digital tools.  After disallowing the software, written by Hany Farid & his team at Dartmouth, the judge ultimately disallowed a human witness, ruling that neither one could adequately distinguish between real & synthetic images.  The story includes some short excerpts from the judge’s rulings, offering some insight into the legal issues at play (e.g. "Protected speech"–manmade imagery–"does not become unprotected merely because it resembles the latter"–illegal pornography, etc.).

As I’ve mentioned previously, Adobe has been collaborating with Dr. Farid & his team for a few years, so we wanted to know his take on the ruling.  He replied,

The news story didn’t quite get it right. Our program correctly classifies about 70% of photographic images while correctly classifying 99.5% of computer-generated images. That is, an error rate of 0.5%. We configured the classifier in this way so as to give the benefit of the doubt to the defendant. The prosecutor decided not to use our testimony because of other reasons, not because of a high error rate.

The defense argues that the lay person cannot tell the difference between photographic and CG images. Following this ruling by Gertner, we performed a study to see just how well human subjects are at distinguishing. They turn out to be surprisingly good.  Here is a short abstract describing our results. [Observers correctly classified 83% of the photographic images and 82% of the CG images.]

Elsewhere in the world of "Fauxtography" and image authenticity:

  • In the wake of last summer’s digital manipulation blow-up, Reuters has posted guidelines on what is–and is not–acceptable to do to an image in Photoshop. [Via]
  • Calling it "’The Most Culturally Significant Feature’ of Canon’s new 1D MkIII," Micah Marty heralds "the embedding of inviolable GPS coordinates into ‘data-verifiable’ raw files."
  • Sort of the Ur-Photoshop: This page depicts disappearing commissars and the like from Russia, documenting the Soviet government’s notorious practice or doctoring photos to remove those who’d fallen from favor. [Via]
  • These practices know no borders, as apparently evidenced by a current Iranian controversy, complete with Flash demo. [Via Tom Hogarty]
  • Of course, if you really want to fake people out, just take a half-naked photo of yourself, mail it to the newspaper, and tell them that it’s a Gucci ad. Seems to work like a charm. [Via]

Photographing Saturn; Rocking Jupiter

NASA’s JPL has surveyed the public & posted the favorite photos of Saturn taken by the Cassini-Huygens mission. You can see more from their collection here. [Via]  And if you’d like to try your own hand at photographing the planet, see Space.com’s advice on how to Capture the Lord of the Rings (with a little help from Photoshop).

The space connection keeps reminding me of a drive-by beat-down administered to the band Train (the guys who brought you "Drops of Jupiter," and who have apparently sold four million albums–to whom, no one knows): "Watching her cry, I knew Benchley had hit bottom. I had reached the mythical state of total anti-rock, which I call ‘Train,’ after the band. When the head of every drum is torn, and all guitars out of tune, when the microphone melts in your hand, that’s Train, and I was in Train all the way up to my drops of Jupiter."

Genetic mutation named after Photoshop

Psst–read any good overviews of the Functions of the Nonsense-Mediated mRNA Decay Pathway in Drosophila Development lately?  (Yeah, who hasn’t, I know…)  I mention it because a mutant phenotype (specifically, a fluorescent protein in fruit flies) has now been nicknamed "photoshop" by researchers Mark Metzstein & Mark Krasnow.  ["Shouldn't that be Adobe® Photoshop® software?" murmur a dozen voices in Adobe Legal. ;-) ]  They write, "We named this the ‘photoshop’ phenotype because it increased visualization of clones like that achieved by digital enhancement with Photoshop software (Adobe, http://www.adobe.com)."  [Ah, says Legal.]  As a highly nonsense-mediated individual, I say very cool, guys!

Chemical Romance, Daahk Mattah, & More

  • Apple.com features the work of Harvard/MIT researcher Felice Frankel, showing how she uses Photoshop to depict the beauty in a chemical reaction (see animation).
  • In their continuing quest to blow my little Arts & Legos mind, scientists have unveiled a 3D map of dark matter (see larger image). [Via]  I had to smile on this one, remembering that the Photoshop CS1 was codenamed "Dark Matter."  In one of the early go/no go meetings, Adobe CEO Bruce Chizen–who is from Brooklyn & very much has the accent to prove it–joked, "I’d really like to thank you for picking a name with two ‘R’s in it.  Daahk Mattah…"
  • It’s not imaging-related, but the Celestron Sky Scout has been a huge hit at the Nack compound.  (I have it on good authority that I was recently hitched, but you wouldn’t know it on these cold, clear nights: la esposa keeps bailing on me to learn about the heavens courtesy of the Sky Scout!)

Decoding scrambled pixels

Removing data from a digital file is sometimes easier said than done. Redacting PDFs has sometimes proven tricky (something the Acrobat team has worked to address), and now a research report notes methods for unscrambling numbers or text that have been obscured via simple Photoshop tricks. [Via]

I asked a few Photoshop engieneers for comments & got some useful nuggets:

  • Gregg Wilensky says, "The ability to recover text that is blurred is limited by the amount of
    noise in the image (and knowledge of the blurring function). So, adding
    a bunch of noise to the image is better, but still not foolproof. I
    would suggest completely replacing the text with noise and blurring that
    (for aesthetics)."
  • Jerry Harris notes, "Having a known set of limited targets, OCR numbers in his example, makes the
    reconstruction task a bit more realistic in terms of useful results than
    most."
  • And Todor Georgiev writes, "Using a known set of blur kernels (those in Photoshop!),
    and a known set of targets, limits the set of possible outcomes
    and makes this technique work. But slightly change lighting
    and/or use custom blur filter, and your data is safe."

Atmospheric photography

  • Marc Pawliger passed along this gallery from PhotoAstronomique.net, containing some interesting time lapse stuff.  Shots like this one make me remember how much I have yet to learn about my camera.  As the text is in French, I can’t read much of it, but I think "Arc de brume" sounds great. [Update: Here's the site in English.]
  • Seeking atmosphere of a different kind, Nicole Bengiveno has captured some beautiful impressions around NYC.  (The music may or may not be your cup of tea; I preferred to nuke it and focus just on the visuals.) [Via]

More animals in the womb, plus a space shot

  • A number of folks have commented on the amazing images of animals in the womb, so I’m following up with some more info I’ve found.  In support of the special program airing tonight on its namesake channel (9PM PST), National Geographic has posted some great online resources, including a video preview, an interactive timeline, and more photos. The show is scheduled to air tomorrow night as well.
  • This NYT story about last night’s launch of the shuttle Discovery includes a couple of really dramatic photos. NASA.gov has another, as well as an image of the shuttle’s rotating service structure at night. (Seeing that shot, I can almost smell the airplane glue & feel the Xacto cuts as I struggled to build a model version years ago. That effort did not end well…) And here’s a video of the launch.

  • Created in After Effects & Lightwave by XVIVO for Harvard biology students, The Inner Life of a Cell depicts mighty mitochondria and the like doing their thing; check it out in high- or low-res Flash video. [Via]
  • Among the more unusual images I’ve seen, here’s the sun shot through the Earth, displaying neutrinos that pass through the planet’s mass.
  • Speaking of celestial imagery, this month’s National Geographic features stupendously gorgeous images of Saturn–just a hint of which can be found on their site.  [See also previous]
  • Rick Lieder must have the patience of Job, and it pays off in his insect macrophotography at BeeDreams.com [Via]
  • BibliOdyssey has posted The Concept of Mammals, a collection of antique critter renderings. "As was the fashion of the time," they write, "the animals were placed in contrived settings and often given human facial qualities, which only serves to heighten the sense of bizarre. And thankful we are too." [Via]  The site is jammed with other good bits, including claws, shells, whales, and more.

More stellar imagery (literally)

  • The Photoshop team got a treat today when astro photographer David Malin paid us a visit.  David shared a selection of his work and techniques with the team, and put in some good requests (some of which we are delighted to be addressing).  His site features a wealth of photos, including 50 Favourite Images from the Anglo-Australian Observatory. 
  • Along similar lines, I recently discovered a collection of 100 Great Images from the Hubble, as well as this stunner.  And speaking of the famous telescope, in response to the news that it’s been decided to keep the Hubble flying (yeah!), the NYT has posted a short essay on the history of "NASA’s Comeback Kid." As always, if you want to open the raw imagery from the Hubble directly in Photoshop, check out the free FITS Liberator plug-in.
  • My friend Phil Metschan, an art director at ILM, has created some concept art for his rocket-science brother’s proposed space flight technology. (More pix are on pp. 41-45 of the PDF.)  It’s kind of funny for me to think that just a few years ago Phil and I were in NYC, building the Gucci site in Flash.  Seems a world away now…

[At the other end of the size spectrum, David has created some beautiful micrographs from very tiny subjects (crystals, etc.).  The images remind me a bit of Mac pioneer Bill Atkinson's ridiculously lovely coffee table book Within the Stone.]

Drawing tools: Rat brains, willows, and Director

  • Mikons is "a new form of self-expression that connects people through visual symbols (personal tags)," and the site creators call their Mikon Machine (created using Director) "the most advanced drawing tool of its kind available on the Internet."
    They plan to add color, text input, a product builder, and a store to enable artists to sell their designs.
  • Cumulate Draw offers a some similar capabilities but is done by leveraging the scripting engines built into modern Web browsers [Via]
  • If having humans in the loop gets you down, why not try a little tree art? British artist Tim Knowles attaches pens to the branches of various trees, letting them draw whatever the wind dictates.  I’m having trouble getting the photos to appear in my browser, but here’s a link in case you have more luck.
  • Not out there enough for you?  Okay, how about 50,000 rat neurons in a petri dish driving a robot arm in Australia, translating neural activity into drawings? Read all about it.

Beautiful scientific imagery

  • The Cassini space probe has produced a stunning image of Saturn and its rings.  The panoramic view was created by combining a total of 165 images taken by the Cassini wide-angle camera over nearly three hours. Color in the view was created by digitally compositing ultraviolet, infrared and clear filter images and was then adjusted to resemble natural color.  Check it out in high res.  [Via]
  • Elsewhere in space, Wikipedia features a great shot of a sunset on Mars (in no way to be confused with Breakfast on Pluto).   And in case you missed it earlier, check out that shot of the space shuttle in front of the sun.  As a celebutante would say, "That hot."
  • Slightly closer to Earth, the NYT has a story and slide show of backyard rocket builders in the desert. Their creations–some able to fly to 94,000 feet–are a bit more impressive than my old DIY constructions (paper towel tube, "D" rocket engine, and as many Black Cats as I could cram in). Yeah, but mine blowed up real good.
  • And much, much closer to earth, the NYT shows the entomological images of Dr. Thomas Eisner. This bombardier beetle is out of hand, though the shell constructions seem a little close to the rogue taxidermy of MART.

Photoshop & the Dead Sea Scrolls

Ah–here’s a great example of a non-traditional use of Photoshop that I’ve been wanting to share for a while. Researchers at USC’s West Semitic Research Project have been using Photoshop to aid in analyzing the Dead Sea Scrolls and other historic texts. Dr. Bruce Zuckerman, director of the WSRP, writes, “Adobe Photoshop CS2 is the single most important enabler in the WSRP’s work. It is pivotal to our ability to unlock the history of the ancient past.” We’ve put together a 4-page article (PDF) that talks more about the work:

Frequently, Photoshop CS2 is used to combine parchment or papyrus fragments of texts that are often physically separated in different museums and libraries in what amounts to digital jigsaw puzzles. Some writing is so tiny that researchers use a fiber-optic “light brush” to direct a very narrow beam of light onto a small area. In such cases, Photoshop CS2 allows scholars to combine images to build composites out of the smaller images. Some writing cannot be seen at all because the background is too dark or the ink itself is too faded. In this case, researchers use infrared and ultraviolet imaging to reclaim the ink traces. Because infrared and ultraviolet images sometimes hide as well as reveal data, scholars use Photoshop CS2 to combine various images in order to have all the visual information available for viewing.

Photoshop & bugs (the exoskeletal kind)

Now that we’ve squashed some bugs in Photoshop CS2*, we can look at an instance of the tools being used in conjunction with actual insects. Microscopy UK talks about photographing slide mounts using a combination of digital SLRs, microscope, and slide scanner. The Photoshop content here is limited, so I’m passing it along as much for the great high-res imagery as anything. [Tangentially related: Berkeley scientists have been inspired by insect vision to create new camera lens designs.]
* Speaking of Photoshop and bugs (the other, bad kind), there’s a Photoshop Top Issues RSS feed as well as a dedicated product support page. If you see something going haywire, please let us know (and send us your feature ideas, too). We probably won’t respond to each report directly, but we do read them all, and we use the info to guide product planning. Thanks.

Scientific illustration in Photoshop

Keeping the science theme going, I’ve gathered some examples of Photoshop’s use in scientific illustration:

By the way, on the subject of scientific illustration, I recently discovered Albertus Seba’s Cabinet of Natural Curiosities, an amazing collection of 18th-century illustrations of animals, plants and insects. And if that’s up your alley, see also Dream Anatomy, a collection of antique anatomical renderings drawn from the National Library of Medicine. [Via] Or for a more modern spin, see the adorable (?) squirting stomachs of I Heart Guts [Via].
[PS--6 minutes after I posted this, a copy of Cabinet of Natural Curiosities showed up at my door. Score!]

Photoshop & Rocket Scientists

News of astronauts firing an empty space suit into orbit (seems like such a dude thing to do, doesn’t it? “Heh heh–when it hits the atmosphere it’ll blow up real good, heh heh”) got me thinking about Photoshop’s role in space imaging.
Data captured by the Hubble Space Telescope & other high-powered telescopes are stored in the FITS format, as packets that need to be re-assembled for use on computers. To make the public-domain data widely available (beyond the 900 or so pro astronomers in the world), a team from the European Southern Observatory, ESA, and NASA created the FITS Liberator plug-in for Photoshop. NASA’s Hubble Source features an article on creating your own color Hubble images using the tools together. As of version 1.6.05 FITS Liberator had some 50,000 users, and version 2.0 (released in August) takes advantage of new 32-bit HDR imaging support in Photoshop CS2.
Check out the image gallery, and drop us a line if you try out FITS Liberator with Photoshop. We’d love to hear your story & see your images.

Image authenticity & Photoshop

The topic of verifying image authenticity, covered well in the NY Times article It May Look Authentic; Here’s How To Tell It Isn’t, continues to draw considerable attention. Photoshop of course gets pressed into duty on the falsification side, so Adobe staff have been fielding a number of press inquiries on this subject.

What may be less obvious is Adobe’s interest in the other side of the coin: image analysis & authentication. Last summer Dr. Hany Farid (mentioned in the Times article) spent his sabbatical from Dartmouth at Adobe, collaborating with the Advanced Technology Group on tools & techniques for detecting image manipulation. Photoshop is heavily used by a wide range of government & scientific bodies, aiding in everything from detecting forged checks (you’d be amazed what a few adjustment layers can reveal) to cleaning up satellite imagery to analyzing the Dead Sea Scrolls (more info on that soon). At the request of image retouchers who need to document their work, we added the Edit History Log, making it possible to store a textual log of edits done to an image (essential for reproducibility). Combined with the ability to embed raw files as Smart Objects, this feature makes it possible for a Photoshop document to contain essentially the negative, the print, and a printable record of edits performed.

For more on Dr. Farid’s research & tools, see his own site as well as this National Geographic article on detecting forged artwork. For more on Photoshop in scientific imaging, Adobe.com now details how scientific features have grown over the last few releases, alongside white papers on best practices.

Todor & Jeff’s Image Science Hut: Coming Thursday

No, they don’t wear fezzes and matching shirts, but resident brainiacs Todor Georgiev and Jeff Chien have been behind some of the more eye-popping features in the last few releases of Photoshop, including the Healing Brush, Patch Tool, Match Color, Smart Sharpen, Reduce Noise, Perspective Crop, and Spot Healing Brush.
I mention this because Todor will be speaking at the next Silicon Valley ACM SIGGRAPH event, taking place on Thursday the 17th in Cupertino. For background, here’s a PDF on the kind of thing Todor will be discussing. My fellow product manager Ashley Manning will kick things off with a demo, and Jeff should be on hand as well. (Oh, and there will be schwag.)

Droppin’ some science

Psst–hey buddy, seen any good kite-borne photos of Estonian peat bogs lately? You would if you checked out the winners in Science Magazine and the National Science Foundation’s Visualization Challenge [link via PhotoshopNews]. But if your tastes run more towards the secret life of the pea weevil (really!), check out the Visions of Science Photographic Awards. Winners include revealing images that were colored in Photoshop.
Photoshop wasn’t designed for scientific imaging per se, but we’re learning quite a bit about how it gets used in a broad range of applications. Last year I got to visit NASA’s Johnson Space Center. The team preparing the next shuttle flight requested better measurement tools that could aid in the analysis of the shuttle’s heat-resistant tiles. (They also mentioned a rumor that a copy of Photoshop has even found its way onto the International Space Station–evidently several astronauts are avid photographers–but I’ve never been quite able to confirm that.)
We’re working to build up info and resources on Photoshop in the sciences, as well as its uses in engineering and other disciplines. If you’re using Photoshop in these fields, and/or if you have ideas on how we should develop the app to suit your needs, please let us know. Post a comment, or drop us a line.
Thanks,
J.
PS–Apple’s scientific computing pages mention numerous uses of Photoshop, including the Visible Human Project.
PPS–Good luck to this group of 7th & 8th graders, who want to send film into orbit and then analyze the results in Photoshop.
