Hi Gilles,

That still means I have to convert twice: JPEG -> TIFF and back.

Enhancing the colors is an operation which is so quick that it can be applied while loading.

For this, many PC programs just note the change (new Gamma, whatever) without touching the JPEG data.

So I'm not talking about simulating The GIMP or something but for tiny retouching work (like "Make all images in this album 10% brighter").

I'm not sure how far this can extend. It depends on the speed of the computer (the change needs to applied every time), etc.

Also, I specifically might not want to change the original image (keeping the option to always revert back) without having to manually manage all the copies.

Think of Joe Sixpack, who just got his first digital camera. He's busy making photos. On the computer, they look dull. So he enhances them.

Later, he learns a much better to improve the images.

But the old mistakes are now saved for eternity.

Also, the c't (big German computer magazine) would rate digicam better, if it could do this non-destructive filtering.
