What files types do you archive? Historically I have saved the original raw file, a jpg, and a DNG. DNG has been around long enough now that I am considering not saving a jpg. For a while I was saving tiffs that were uncompressed, but that really did fill up a hard drive in a hurry. Of course then the files we started with were much smaller as well.
I wonder how we will be archiving files in 20 years and how much of what we are saving now will be readable then?
