Hello all! I am having a recurring problem when editing my pictures so I think my technique must be wrong or what I want is just not possible. I've uploaded a contrived example for you to see the problem.
What I want to achieve, is to play with the levels of the sky (adding contrast, etc) and also do the same for the ground separately.
The problem is that I always end up with an ugly light border around the horizon, as you can see clearly on the right of this image - and all along if you zoom in.
The way I currently do it is like this:
- create two duplicate layers of the original image and give them both an empty layer mask - one for sky, one for the ground
- then using the magic wand/fuzzy select tool I select the sky outlining the horizon
- then, in the ground layer mask I fill the sky selection with black so all manipulation only affects the ground
- then I invert the selection and in the sky layer mask I fill the (now) ground selection with black so all manipulation only affects the sky
- after that I do all the lightening/darkening on the sky/ground
If anyone has any tips or ideas out there I'd really appreciate it. Oh btw I use gimp but I don't think doing the same thing in PS would be any different
