I hope that I can present this question clearly. I process 2 images from a single RAW, a light and a dark. I create a luminosity mask from the light image, and then from that selection I create a Layer Mask on the dark image.
1) Why does the resulting composite have strange colors, like a bad Curve (where it goes up to the right, and then goes down before continuing back up to the right)?
2) Why is there marked improvement with a Gaussian Blur of 40 to the mask?
3) When I paint on the mask in mid-gray, that section similarly improves (that would be the same as 2, ie, a homogeneous gray like a blur).
What does the Blur actually do to improve the blending? I’m sure it has to do with how the pixels are blending without the blur, but I cannot seem to understand what’s going on.
The images are in perfect registration.
Thanks very much,
Sonny
