| I'd open the two halves as completely different documents, put 4 color samplers on 4 colors they both share (or at least that you feel need to match in both). Then I'd write down the values from one image and use curves to set the spots on the 2nd image to match.
For example, if in image1 the sky sampler says R128,G171,B222, I'd move to image2 and open the curves dialog and precisely position my cursor over the new sky color sampler and ctrl-click to put a point on the curve. Then I'd use the up/down arrows (only, never left/right arrows) to move this point until it matches the image1 values precisely.
Repeat with other samplers. |
