You might consider looking at Adobe Lightroom. This software allows
for manipulation of the image, single or in batches (it can also
develop raw files), but it doesn't touch the original file unless
specifically instructed to do so. All manipulations are retained as
metadata and can easily be reversed one by one. Altered images can
be exported as separate files. Lightroom is also great for sorting
and viewing images, and its very easy to use. It has a few bugs, but
since the current version is 1.0 I expect that these will be fixed
in the future.
