phybron Posted June 30, 2006 Share #1 Posted June 30, 2006 Advertisement (gone after registration) I've always tried to resist the RAW mode on my D2 mainly because I don't think I can process the pictures as well as the camera can in best quality JPG mode, the write time sucks and all the comparisons of RAW and JPG I've ever looked at seem to be about the same and in some cases the JPG looks better to me. I'm quite happy with this, with only a minor nagging feeling that I might not be getting the best out of my camera. My 11x14 canvas prints look fine. I now have Aperture which would make RAW files easier to deal with than any programme I've had before so am tempted to make the effort, possibly. Before I go down this potentially time-wasting and unsatisfying route I was just wondering: are my JPG's being compressed (and quality reduced) three times during my usual workflow process which is: a) take the picture import to Aperture and make minor changes c) export as JPG for uploading to web Does the importing stage add another compression or is it just a straight copy? If not I think I'll just stick to JPG's seeing as they're so much easier. Right that was a lot of blather to ask a simple question. I don't need another RAW vs. JPG debate - just wondering how much I'm nullifying the decent lens with my shoddy workflow. Link to post Share on other sites More sharing options...

john_r_smith Posted June 30, 2006 Share #2 Posted June 30, 2006 Phil as I understand it, the only time a JPEG file actually suffers a quality loss is when you save it, and the image in the PC memory gets compressed again to disk as a result. The act of opening a jpeg file does not result in a quality loss - your PC image display and editing space does not know or care about file formats, as you will see if you check the memory usage - a Digilux 2 3.9MB jpeg is expanded into 14MB of memory, just the same as an 8-bit TIFF. If you wish to work on a JPEG file and save it at intervals, the thing to do is to save it as a TIFF at the outset, do your editing, and then save it back as JPEG again at the end of the process.

phybron Posted June 30, 2006 Author Share #3 Posted June 30, 2006 Ok so it's not being compressed again on import. So only twice in my workflow. Well that's not so bad. I can hide from RAW for a bit longer then Thanks. Link to post Share on other sites More sharing options...
