But it affects your perception and awareness of the values! If you don't see the changes, you cannot be aware of the values!

Agreed. And that was the OPs question (whether there is any substantial loss in resaving a JPG, say 2-3 times?). Recompressing 2-3 times does not produce visible changes in the image.

You go ahead and do it, since you evidently love to do things blindly.

An excellent proposal. I have the necessary hardware to produce high quality prints and access to a group of photography students to use as the jury. I will do it and report back here with the results.

Sorry, but what you have been showing me are what I would regard as blind-man's tests.

Thanks, the Justice is blind, you know..

I don't use JPEGs otherwise, so at this point, I'll be happy to let you have the last word.

Thanks, that's very chivalrous of you.
