Okay, this is something that is getting rather annoying for me, and I just wanted to know if there is a setting for this. I save out a jpg from another program (usually Bryce for me) and open it up in Photoshop to work on it. When I am done working I usually just hit save. If the last jpg I saved was at really low quality, it will automatically save the jpg I was just working on at low quality. Hence, I have just screwed up my render and have to go back to Bryce and render again. I know I should be saving a master copy of all my renders, but occasionally I don't. I use Photoshop 5.5, I know it's a dinosaur, but it's what I got. Any suggestions besides saving master copies?

When you say "Just hit save", do you mean with a shortcut key combination (alt+s) or in the File menu? If it's with the shortcut key, the answer is simple - stop using the shortcut. If it's the manu, have you tried Save As?

I had a few issues with .jpg I have version 7, I did a save for web, chose my own settings and hit ok, it replaced the original file.jpg,(this is what I wanted) then I quit Photoshop and then it asked me "do I want to save the image" and I clicked yes >> bad idea because I wasn't able to choose the settings, and it saved over my special save for web file I already had. I find it wierd now , that I have to save for web and then tell it not to save , when I close it. I thinks "save as" will help both with copy's of renders, and choice of image quality. even if you hit "save" automaticly, "save as" can rectify the situation. you don't really determin the quality untill you close the image you are working on / type in the filename.

do your best NOT to save your file as a "jpg" again until you are sure you're not going to work on it anymore. it is far better to save a copy in Photoshops native "psd" format and save as "jpg" only when you're finished.

each time a "jpg" file is open and saved it is recompressed and thus "squishy-ed" more, causing artifacts to crop-up...

karosnikov, that happens in Photoshop 6 as well. Save for Web isn't considered as "saving" the image for several reasons. 1. Quality --JPGs are lossy; it's not good for a final copy. 2. PSD Files --Most users save their ongoing projects in PSD files. Saving to Web does not save that PSD file - it has to be saved independantly. Therefore, if you were working on a PSD, Saved to Web, and then closed down, you wouldn't have saved the PSD! That's why the "Save?" dialog box comes up.

I'm saying I saved the original .jpg (higer setting) over my save for web (lower setting) , my final copy was for web.
