I got a general question about dealing with file formats. Normally I take raw photos and process them in darktable, and I could say that raw processing is the most “lossless” processing of course.
Now lets say, after the raw-workflow, I want to fine tune some things; and for giving an extreme example, lets say:
I export a fullsize jpg out of darktable. Then edit in in gimp and overwrite the jpg. Then opening in photoshop doing something and also overwriting the jpg. And so on…
Question: is it correct that, with every edit&saving process (jpg) the quality gets worse and worse because of jpg compression (even with 100% of quality) ?
And now my second question is: Would TIF be the perfect format for this case because it does not (if not enabled) compress? And is it also correct that I could theoretically jump between the two examples above (gimp and photoshop) as often as I want without loosing quality because of TIF?
I know TIF is a very huge filesize; in that case where I would have to “jump” between programs I would create a TIF out of darktable, edit it and finally create a jpg and then delete the TIF so that the size would not matter in the end.
I hope I could post my question clear enough.
Thank you folks
