Still peeking through God’s Window. Weather is horrible. With greatest effort Blyde River can be spotted almost on horizon.
Two instances of retouch module in dark table, slightly larger distance to sample area than default, sorted out corner vignetting. That two instances are two iterations, to clear possible confusion.
I haven’t still looked at your xmp file, but I’d say that you don’t need two instances if your goal is to retouch two different areas of the image. After the first retouch, just click on one of the retouchin shapes and click on another area of the image.
Need two instances since single one doesn’t make it look natural/smooth. Yes I am retouching left and right corner simultaneously, do not really see benefit of separating them, give computer workout?
Used Manual lens profile correction and Distortion correction modules of RT 5.5 to remove the vignetting. Spent some time on the definition of clouds and getting the colors right. FED_1966.jpg.out.pp3 (12.3 KB)
To remove vignetting, you can use curve with inverted drawn mask (circle).
With the help of the slope of the curve and mask refinement you can then adjust the gradient of the mask to neutralize the vignetting:
That is rain is starting weather conditions. So, go low key, no vivid colors. Both processing woud be 100% if those bright green switch towards gray-green
Actually, to be clear, I didn’t boost chroma in any way because most if not all of my processing acts upon all of the colour channels the same manner. I would say the weakest link might be the core parts of Retinex and the first sharpening because it is not completely my code. Also both Retinex and any sharpening that I use has clipping.
