If you are not familiar with Adobe’s DNG file format DNG stands for Digital Negative. It is supposed to be lossless and I’ve seen no reason not to believe this as far as processing is concerned.

Google “Adobe DNG” for much more than you ever want to know.
Anyway, DNG saved a troublesome situation for me.
