One of the realities of Gimp is it doesn’t have all the tools Photoshop does. In her post How To Replace A Sky In Photoshop, Helen Brady used a feature called “Blend If” in the blending options panel. This feature is great at helping replace a blown out sky but it doesn’t exist in Gimp. So, with her permission, I’ve taken her basic instructions and tweaked them to gain the same results from Gimp.
Without further ado, here is one useful method for replacing a sky in Gimp.
1) Fire up Gimp and open an image needing sky replacement and then drag in a sky image to the Layers panel. Rename the dragged image “Sky”. Click on the eye icon to the left of Sky to hide it from view for now.
