hi

is it possible to remove render effects from image just saved? I'm
speaking about effects superimposed to jpg image with photoshop.
Is it possible to show if an image was manipulated in such a way?

thanks

if you didn't close the document you could still go back in the history to
before you rendered. If not lesson learned.

Of course none of us here would think of working on a jpg without saving a
copy of the original.
You should always save artwork in layers in a psd document so you can
produce jpg from that in many versions with no degradation and of course to
preserve a copy of the original file untouched.

No.

Once you have flattened the image, that's it.

When you use for exemple the clonetool you modify the structure of the
image, introducing descrepancy with the wole. I think that is
statistically possible to show this descrepancy, nobody knows if this is
a real approach? About the rescue of prerendered image: does photoshop
not save a thumbnail of the original image?

thanks
