The wiki for DNG states:
"In digital photography, the Digital Negative (DNG) file format is a royalty free RAW image format designed by Adobe Systems. Its specification was announced on September 27, 2004.[1] The same day, Adobe introduced Digital Negative to the market with its free of charge Adobe DNG Converter program. According to Adobe, Digital Negative was a response to demand for a unifying camera raw file format.[2] Digital Negative is based on the TIFF/EP format, and mandates use of metadata. All Adobe photo manipulation software (such as Adobe Photoshop and Adobe Lightroom) released since the announcement support DNG.
Adobe is submitting DNG to ISO for standardization.[3"
I hadn't thought much about it because my camera's raw actually is already dng format. Guess my camera choice saved me a step in ensuring ability to continue to use my files for years to come in raw format.
My main choice for using raw is that I am not a master at getting my lighting right so it gives me a chance to fix what I should have known to do on site but didn't manage to.
The concern I believe is backward compatibility.. think back to when floppy disks were the usual.. now, try and find a floppy drive unless you have an old one hanging around.
BTW, very cool experiment! and thanks for sharing it.
