DNG Verification in Lightroom 5

I’ve been looking forward to the day this can be announced since 2007. In Lightroom 5, there is now a one-click solution to verify an entire collection of DNG files. It’s a really simple idea, with pretty huge ramifications from a data management standpoint. Interestingly, it’s nearly absent from any Adobe marketing materials for LR 5.

DNG Compatibility Settings

Adobe Labs has updated DNG conversion options in Lightroom, ACR, and the DNG Converter that offer some (possibly confusing) new options. You now have a preference pulldown for compatibility settings. What’s up with that? The short answer is that new functionality has been added to the DNG specification (and to the latest version of Camera Raw) that can do new tricks to the pictures.

For instance, there is now a way for Adobe (and others) to remove lens distortion from the image. ┬áSince this is a new function, it’s necessary to make a new version of the spec that details how to save and apply the instructions. One thing this enables is for cameras that don’t work well with the current DNG spec to now be supported. Check out Tom Hogarty’s blog to see the new camera support.

Some new DNGs that make use of these new tools won’t be fully compatible with all DNG applications. You can save them so that they will work with the older software, but they will lose some of their rawness. How the heck does one decide which to use?
