I use to own a pentax ist ds and I chose to take photos in the raw format which for pentax was ".pef" files. Now when I edited this pef file the original remained unaltered but a small file which was a .xmp was created and that held the information for the settings you altered leaving the pef in its original state.
In my new pentax k20d I can choose to save as adobe raw ".dng" as well as ".pef". I chose .dng this weekend. Now I noticed when opening the .dng file and making alterations to it. These alterations were actually saved to the dng file and not another file.
So my question regarding adobe .dng files is...will making repeated alterations to the file degrade it (as it is saving over the file unlike .pef which creates a .xmp file)?
