As you know, I posted this photo on another thread, to learn about different de-blurring techniques. I wanted to use the Unshake program exclusively, to try a little testing. What I did, was to take the stock photo, run it through, only changing the time to x2, then running that result through it again, with the same settings. Here are the results. Stock photo:

Test 1:

Test 2:

Test 3:

Test 4:

Test 5:

Test 6:

Test 7:

Test 8:

As you can see, it did clear up a bit each time. It did get slightly darker each time as well. The later results had some slight change, but were basically negligible.

Here's an animation, showing the difference between the stock photo, and the last test. A significant difference:

Here's an animation showing every layer change. Changes are 1 second apart:

Thanks for looking.

That's awesome. I don't think the darkening is a problem here, and the whites still stay white, just seems to be a lot more contrast.

I agree. The darkening is no problem at all. Even if it were, it would be easy to lighten back up.

Impressive; is it a GIMP plugin? :)

It's a stand alone, but you can run it through Shellout, if you're smarter than I am, haha.

Attached is an LAB color corrected copy of your original image. I decomposed to LAB, A/B curves and L Unsharpen mask. It seems to improve the clarity of the base image. Try a go with the LAB layer.

You can run it through Shellout with a bat file.
