I'm working as a stock photographer and i'm not sure how to save my images. Save as / save for web? I need the best possible quality without banding or loss of quality. Clients print my images and also use them for their webpage. What should i do? Also, 8 bit or 16 bit?
There should be some guidelines from your stock site on the technical specifics of the file.
I have always used the 'Save As" with the 16 bit as a normal with no problems. I just set the baseline to 12 (max quality) when I save from PS. I have posted and sold some from Fotolia (Adobe Stock) this way with no problems.
