Thanks, Brooks!

I posted this to one or another of the DPReview forums, to the FourThirdsPhoto.org forum, and (I think) to the GetDPI.com forum when I noticed that LR v2.6 finally did the right thing with respect to Panasonic LensID information. Funny that Google doesn't find it.

Regards complexity, I dunno that this is so much different from other silliness in our daily lives. It seems to be amazingly difficult to set up a television service these days, and then to install and use a modern television's bazillion features is utterly confounding. Used to be you just bought the TV, plugged it in, and twisted the rabbit ears around until it looked good.

Photography has always been a technological medium, with a river of complexity under the surface, even in the days of film and prior. With the advent of digital image capture and processing, and management, ... and all the other stuff we take for granted now ... that river of complexity has swelled to an ocean.

My education and career netted me insights into this technology that I enjoy sharing .. that's one of the reasons I started teaching workshops last year. It is both uplifting and a delight to help.

BTW, I agree: Adobe should hire me. ];-)

There's more than one person who knew that DNG could incorporate the sidecar data directly into the file. I learned that some time ago, I think on Lynda.com, probably from one of Deke McClelland's videos. I've read it other places as well.

Check the Adobe website http://www.adobe.com/products/dng/?promoid=DTEHA. Under "Key Benefits" it states that "The specification allows for the addition of private metadata to DNG files, enabling differentiation."

A word of caution that I have unfortunately found in saving metadata to your DNG file is that your original DNG "negative" is overwritten. After saving metadata on an image that I cropped and developed I found that I no longer had the original image should I wanted to re-develop (it also eliminated the history on that file as well). Hope someone out there has a workaround - Since I did this I have been working with copies or virtual copies. Thank goodnesss for having an original DNG backup philosophy.

In Lightroom, just click on the RESET button and it will take you back before you did any edits to the DNG file.

In Photoshop, while opening the DNG file with Camera Raw, click on the far right set of options SNAPSHOTS and select the IMPORT snapshot. That will let you open the original DNG before any adjustments.

At least these two options have always worked for me. In fact, the whole purpose of DNG and Lightroom's non-destructive editing is to allow this very kind of backstepping to be possible. Give it a try.

Thanks so much for this information! Sorry to hear what you had to go through to get it though...
