I noticed today after importing and converting to DNG's what were supposed to be Raw files that the Mode Dial on my 5D was set at Full Auto instead of Program AE -- meaning of course that the files were JPEG's and not RAW (since I never shoot on Full Auto I expect the dial shifted when I was taking the camera out of its bag and I didn't notice.)

Anyway, my question is: by converting JPEG's to DNG's have I messed anything up or can I treat them as normal JPEG's?

Thanks.

You haven't gained or really lost anything. Well if you want to process them, that means ACR or Lightroom, meaning they will get converted to a linear encoded high bit file while if you had the JPEG's and wanted to edit them in their original gamma corrected mode, you could do this in Photoshop. That said, you probably want to handle them in Lightroom or ACR so, no harm done.

Converting JPEGs in anything increases the loss of data, which is inherent to JPEG anyway.

But how did you achieve this? With Bridge? I am not using Bridge, so I can not compare them, but I guess the raw->DNG conversion can be done much faster by the stand alone DNG converter.

I'm pretty sure you can't convert JPEG to DNG, at least not in the DNG converter, I'm not sure you can from bridge. Wayne

You can do this directly from Lightroom or Camera Raw.

Yeah, that's how I did it.
