Bert, I had a go at processing the before image you posted here, I was curious how my system stacked up against the commercial one...

Here's what I did:

- Load before.jpg image into Astra Image, rescale 2x
- Convert to greyscale
- deconvolve Maximum entropy, 10 turns, radius 1
- save

Load image into The Gimp:
- selective gaussian blur
- levels adjust (Gamma increase to 1.9)
- unsharp mask, radius 1, power 0.5
- scale down to 50% (ie back to original size)

And this is my result. Comparing it to the "after" image from Retinex, I think it's a close thing, maybe I like mine better :-)

If I'd started with a lossless image instead of the before.jpg then could likely improve it a bit more.

cheers, Bird
