DNG Verification in Lightroom 5

There is a new command in Lightroom 5 that will verify the integrity of any Adobe created DNG files (Library>Validate DNG Files). If it finds any invalid DNG files, they will automatically be placed in a special collection.

This validation is helpful when we want to check to make sure that files haven’t been corrupted after copying then from one drive to another. It can also be helpful if we want to know with certainty if anything has changed in the original source image. If something has changed, then we know that something has gone wrong and it can (hopefully) be solved before more damage is done (like additional files are copied or changed).

It’s important to note that the data that Lightroom is verifying is the “original source image” – which, in a DNG file is never supposed to change. Lightroom is checking this information independently of the other information (that may have changed) in the file.

Here is a little more detail (and please understand that this is a bit of an oversimplification): the DNG file contains many different “kinds” of information. It’s helpful to imagine that the DNG file is really more like a file cabinet and each different “kind” of information is stored in a different folder in that cabinet. This enables certain segments of the file (one folder) to be altered independently of another segment (or folder).

For example, if you add IPTC data to a DNG file (by adding keywords, copyright etc.), the data in the IPTC folder changes, but the source image data (which is stored in another folder), remains unchanged. Even when you make edits to a DNG file in Lightroom’s Develop module (or Photoshop’s Camera Raw plug-in), all of the changes are made to the DNG file (as a set of instructions) and are stored in a separate folder so as not to change the original source image data. It’s then up to the software – PS or LR to take the original source data and then apply the set of instructions (from the other folder) and display the results on screen so that it “appears” as if the changes have been made when, in fact, the original source information has not been touched. Of course the benefit of not touching the original is that the entire workflow is then non-destructive: the changes can be modified or removed at any time without changing the original source data.

Here we can see that there are many types of data in a DNG file that can be changed. But the Source Image data should remain untouched.

Here we can see that there are many types of data in a DNG file that can be changed including EXIF, IPTC, AUX, RDF etc.). However, the Source Image Data should remain unchanged – and that is what the DNG verification feature validates.

So, it’s the best of both worlds, you can now validate an Adobe DNG file to confirm that the source image data has not changed, yet still make changes to other information in the file in order to add metadata and enhance the image.

Note: Only DNG files created by Adobe software can be validated (camera-‐created DNGs cannot be validated because they do not contain the necessary checksum).

For more information, be sure to check out Peter Krogh’s in depth explanation.

Hierarchical Keywords in Lightroom 5

Hierarchical keywords are written in a much more logical (and visually obvious) manner in Lightroom 5.

For example if we have the parent keyword “Flower” and want to add the child keyword “Rose” it would be represented as:

Flower > Rose

In addition, it can also be written as:

Rose < Flower

They both result in the same keywords applied, with Flower as the parent and Rose as the child  (notice that the “>” is changing direction between the two examples).

Quick Develop Increments in Lightroom

The double and single arrow buttons in Quick Develop (in the Library module) make the following changes:

• Exposure 1/3 stop, 1 stop

• All others (Contrast, Highlights Shadows etc.) 20 and  5.

• The Temperature and Tint sliders are dependent on the file format. When working with JPEG files, you guessed it, the changes are in increments of 20 and 5. For raw images, the increments for Temperature and tint are also 20 and 5. However in this case they are being calculated in relative percentage terms. (Camera raw translates the relative percentage amount to the absolute temperature and tint value using curve functions – both are quadratic and perhaps not as obvious!)

• Finally, holding the Option + (Mac) | Alt  + (Win) in the Library module will change the Clarity and Vibrance settings to Sharpening and Saturation in the Quick Develop panel.

Applying Virtual Copy Settings to the Master File

There have been times when I have decided that the settings that I had applied to the Virtual Copy are better than what are on my Master. In this case, I can quickly apply the settings from a virtual copy to the master, by selecting  Photo > Set Copy as Master (in the Library module).

Creating A Smart Collection Based on Virtual Copies in Lightroom 5

Although it’s easy to find your Virtual Copies by using the Filter options in Lightroom, (use the Attribute filter and click the Virtual Copy icon on the far right),

23FilterVC1

it isn’t as readily apparent how one can create a Smart Collection that automatically finds your Virtual Copies – but it can be done! In Lightroom 5, choose Library > New Smart Collection and under the Match category, choose  File Name / Type > Copy Name. Then, set the pull down menu to “isn’t empty”.

New Smart Collection Criteria in Lightroom 5

The Lightroom team has added new criteria (filters) for Smart Collections including:

• Size (in megapixels). Note: the sub-options include Long Edge, Short Edge, Width, Height, Megapixels, Long Edge Uncropped, Short Edge Uncropped, Width Uncropped, Height Uncropped, Megapixels Uncropped, and Aspect Ratio

• Bit Depth

• Number of color channels

• Color Mode

• Color Profile

• Smart Preview status

• PNG

Note: the last two options, Smart Preview Status and PNG are also available as Filters.

In addition, Lightroom now remembers your last viewed image in a Collection so when navigating from one collection to another, you’ll be restored to that image upon returning to the Collection.

Quick Tip – How to Remove Unwanted Collections when Exporting Catalogs in Lightroom

In this Quick Tip, Julieanne demonstrates how to quickly clean up an exported catalog of any extraneous collections.

Just as an FYI – I had a great talk with the engineer who works on the Import/Export as Catalogs (after I recorded this video), and he provided an excellent synopsis on why those extra collections are there. As it so often turns out, the topic is much more complicated than my little brain imagined:

The idea is that for every single photo that is included in the export, all information related to that photo is included. Let’s take for example that you have a collection of “Tree”. One piece of information that is related to some of these photos is “I’m in the Tahoe collection” so the Tahoe collection appears in the collection panel, containing those photos.  The Tahoe collection doesn’t contain all of the photos it contained in the original catalog of course, but only the photos that were part of the source (Trees) that was selected for export.

Perhaps this behavior seems odd.  We could change the behavior, but it’s a dangerous, slippery slope.  For example, what if the source you selected for export wasn’t “Trees” or “Tahoe” but instead was a folder that contained photos, some of which appear in both Trees and Tahoe?  Should neither of the collections appear in the exported catalog?  I think if we start dropping information from catalog exports, we’ll quickly hit scenarios where we’re dropping things that customers don’t actually want us to drop.

Hence, you now have a simple work around to quickly remove the collections that you don’t need, while still making sure that you still have the option to see all of the information related to those photos when you do choose to export a catalog. : )

Grid Overlay Options in Lightroom 5

Grid overlays aren’t limited to cropping anymore! In Lightroom 5 , you can choose to display a grid in the Library (while in Loupe view), the Develop module and during Tethered Capture by selecting View >  Loupe Overlay > Grid. Note: by default the Grid menu option displays a dash (not a check) before its name because the overlay is not visible by default. To toggle the display of the overlay, select Grid from the menu (or use Command + Option + O (Mac) | Control + Alt + O (Win).

While the grid is visible, Command  (Mac) | Control (Win) displays options for Size and Opacity. Click-drag left/right on Size to decrease/increase the grid size. Likewise, Click -drag left/right on Opacity to decrease/increase the grid opacity.

Pasting Settings in Lightroom’s Develop Module

In Lightroom’s Develop module, when you choose Settings > Copy Settings or use the shortcut Command + Shift + C (Mac) | Control  + Shift + C (Win), Lightroom copies the setting that you select (in the subsequent Copy Settings dialog), to the clipboard and holds on to them. Therefore, as you move through your photo shoot, you can easily paste those setting to any additional image(s). This might be a great way, for example,  to paste a subset of attributes such as a vignette or color toning to images while moving through a shoot, and still be able to use Sync (or Auto Sync) to apply other modifications.

Saving the Original File Name in Lightroom

Lightroom automatically saves the original file name in the metadata of the file. In the Metadata panel, (in the header area where you can choose from a number of different ways to display the panel), choose the “EXIF and IPTC” or “Location” display options and you will see the “Original Filename” filed.
