The Leap Into A Photography Contest

Photoshop’s Tai Luxon, pictured here, was photographed by me about a year ago. I’ve recently entered it in a photography contest sponsored by Magnum Photos, and it’s doing well. In fact, it’s very close to making it to the final selection.

If you like it you can help by voting for it. Just head over to http://www.atasteforlife.co.uk, click through the age check (you must be over 18 to look at all of the pictures for some strange reason), and then go here: http://www.atasteforlife.co.uk/index.php/gallery/#/2340017212/ to see and vote for it.

I also have a few more entries in the contest (in different categories) of which you can see here.

Your support is greatly appreciated.

What does an engineer do with some free time?

What can I say… I was inspired by both the screensaver on Apple TV and the ease of use of Adobe Flex. So, in a day, I whipped up a little side project that combined those two elements along with the images of flickr.

It is not often I toot my own horn, but in this case toot toot. I’m actually proud of it.

My creation is the flickr ticker.

By default the ticker shows the currently uploaded photos in an Apple TV like stream. But if you go to http://explore.flickrticker.com you will see flickr’s most interesting stream by. Additionally I added a way to show both flickr member’s and photos in flickr groups in this manner. The easiest way to see this (if you are a flickr member) is to use a little Greasemonkey script I wrote (found here).

If you have feature requests or find bugs, let me know.

There’s a pretty cool photography magazine that is created with non-professional content. This magazine is none other than JPG Magazine.

Every issue has a few set themes and if you have what you think are good photos, you can submit them for the chance to make it in that issue.

The photo seen here is my first attempt to make it in the magazine under the theme Street. If you like it, I invite you to vote for it.

Everything is Black and White

Whew, I have some time to breathe so I thought I’d update this blog. Photoshop Elements 5… what can I say? I think it’s probably one of the best releases I’ve been associated with. One of the features I worked on was the Convert to Black and White (C2BW) workflow.

The C2BW feature allows you to easily convert your oh-so-colorful images into art. And with very little work… just a click of the mouse. By default, we try to guess at the settings that will look best for your photo. If it’s orientation is portrait we select the portrait option and landscape, well you get the picture. The interface to C2BW is really nothing more than a simplified version of the Channel Mixer found in Photoshop. But boy is it easier to use. Just start with the preset that you like and click on the thumbnail previews to make tweaks. If you screw up you can always hit the reset button (but you can also undo/redo in increments by pressing ctrl+z/ctrl+y respectively).

And a little hint for all you bit twiddlers… we read in a file named bwconvert.txt located in the <app folder>\Required that manages the settings applied in the presets. If you open that file in a text editor, you can tweak the numbers used. The format is as follows: <preset name>|<red>|<green>|<blue>. Don’t mess with the preset name (and don’t bother adding any presets as the preset list is set in stone), but you can change the values for RGB. And if you do make changes to this file, be sure and make a copy of it before you mess around so you have a chance to undo any possible damage.

Have fun!

Into the blue…




Into The Blue

This is mostly a test post to see how Flickr and blogs.adobe.com play together.

It’s a picture I took during my 6 week sabbatical to Russia, Italy, and France (yep, long trip) at the island of Capri (off the coast of Italy). It was pretty difficult to capture since you can’t use flash (will ruin the lovely blue color). So I scrambled to get the fastest lens I own (a 50mm f1.4) on the camera and shoot it before the rowboat left the grotto. I think we were in there a total of 15 seconds.

Uh, what does this button do?

Welcome to my first entry into the brave new world of the blogosphere. A place where anybody can talk about, well at least in my case, nothing of great importance. Think of it as the Seinfeld of the Internet. :) But, since I’ve decided to stick my little toe in the water, I thought… hey I can talk about nothing too! But Adobe’s not too thrilled about employees talking about jib jab, so I’ll reign myself in a bit and talk about stuff that relates to our products or technology. So, like all good hosts, I’ll introduce myself, bore you to pieces, and probably never see you again.

I started at Adobe in 1999 working on a now discontinued program, PhotoDeluxe (PDx). I got brought on to work on the fourth iteration of the Macintosh version (which never shipped). And in fact, it would have been only the third version (as version 3 was skipped). They had made some changes to the text engine in the 4th version of the Windows project and I was responsible for making it work on the Mac. Prior to coming here I was still in college, so that meant I knew Unix. For most professions in the computer industry, knowing Unix wasn’t so helpful so this Mac thing was a whole new experience. What did I get from it? Well, how about a lack of documentation. Wow. You could find more tumbleweeds rolling about then useful Mac documentation (pre-OS X). But I digress… Shortly after hitting beta, PDx was ended and they moved most of the team over to a whole new program, Photoshop Elements (PSE). Moving to PSE was pretty exciting. Its charter back then was to make the very powerful, but complicated Photoshop more accessible to average people. It was just the type of challenge we looked for. Being a Photoshop user myself it was right up my alley.

On version 1 of PSE, I was responsible among other things for dreaming up Recipes. Recipes were an interactive list of steps to help the user achieve a task. The idea of guided activities were not new (they were in PDx) but one of the limitations of guided activities were that locked the user into a specified process. Not being a huge fan of being told what to do I felt Recipes should merely suggest what to do but still allow the user to try things out and maybe learn as they go. The other features I worked on were some behind the scenes work in the File Browser (which later moved to Photoshop), the red eye removal brush (which later became the color replacement brush), and some Twain (scanner) improvements.

Version 2 was more of the same… I worked on re-architecting the Recipes work (renamed How Tos) and added a search box and interface into the online help system. I also saw the concepts behind Recipes find its way into Acrobat.

The biggest change in version 3 was the “integration” of Photoshop Album (now called the Organizer). I didn’t work on that part, but instead co-wrote the Photoshop Elements Help application (which later became the basis for the Creative Suite Help System). I was also responsible for creating the single-column toolbar. Exciting, eh?

In version 4 I really didn’t have a feature, per se. Instead I was tasked with making the Editor startup faster. When Acrobat 7 debuted, one of their biggest improvements was their startup time. So, I worked with some of the Acrobat guys to determine what PSE could do to take advantage of what they learned. And we saw noticible improvements. In PSE 3 our “cold” startup time went from around 20 seconds to 6.5 seconds in PSE 4. And from around 8 seconds “warm” launch to about 3.5 seconds on the same machine.

PSE 4 was also the first time we staggered our release of the Windows and Macintosh versions. So, shortly before PSE 4 Windows was finished I got pulled off to work on the Mac version. Aside from bringing over most of the Windows Editor features, the major changes were integrating Bridge (the File Browser replacement) and moving from the application being Carbon (CFM) based to MachO.

I’m hoping this blog will serve as a means for Engineering on PSE to communicate with our customers, and allow for a more technical discussion regarding the underpinnings of a solid graphics program. Adobe does keep me busy, so I’m not sure how often I will update this blog, but feel free to check out my other passion.
