JPG degredation

Hi
When saving a camera jpg file in Windows PS is there any degradation when
saving 100% or maximum quality.

Will there be a difference between saving once and saving the 10th time?

Will there be a difference when printing these pictures?

Thanks
J

Yes, it's not a lossless compression even at 100%.

Yes. If you start with a jpeg I'd suggest saving intermediate edits in
tiff or PSD formats, then when you're done editing if you really need a
jpeg do the conversion at that point ... constantly editing and saving
as a jpeg is not the way to go.

Maybe ... depends on how big you print and how often you've compressed
and at what settings. A jpeg that was compressed one time at 100% and
not edited afterwards will actually print very well but the more often
you edit/save the more you'll increase the odds it will look bad with
artifacts ...
