Your processing of W00085699 is superb Val. I wonder if you might elaborate here or in the images sub-forum on how you did this. I worked a bit on the same image and sad to say am too embarrassed to show it now!
Your Titan blog web page was great as well !
Thanks so much!!
So here are the steps I took:
1) Initially I just used the high pass filter on the CB3 frame (W00085699), then adjusted the brightness/contrast, and added a little bit of noise. The result didn't look too different from the original raw image, but the lakes and seas were a tad darker.
2) I came back to it later realizing I could use the RED frame (W00085696) to subtract the brightness changes across the CB3 frame. I stacked two of the RED frames on the CB3 frame, making two identical layers -- let's call them [a] and [b]. (So now there are three layers total: the background, CB3 and the other two RED layers.)
3) I adjusted the Gamma on each layer so that [a]'s was set to 1.4 and [b]'s to 0.6. Then I inverted both layers. After that, I set the blend mode of [a] to Linear Burn and changed the opacity to about 50% -- so the lakes and seas could be seen and it wasn't too bright or too dark. Then I set the blend mode of [b] to overlay and didn't alter the opacity.
4) I finally merged all the layers together, used the high pass filter, and adjusted the brightness/contrast.
I hope that helps!
