I photographed this little house at Brookgreen Gardens recently in midday light. The flowers that frame the scene were quite bright and the house darker than I wanted. In just a few minutes I created the image I had in mind, highlighting the house.
Open Image and crop if desired
Add new layer – create new layer icon on Layers pallet next to garbage can
Edit – Fill – 50% gray and change the Blending Mode to Overlay
Clicked on the brush and using black and white paint on the 50% gray layer I darkened around the edges and brightened the house.
Very simple and non-destructive on its own layer!
