1 Make a new hue/saturation layer and raise the saturation to +20. Set this layer at Soft Light 100% Duplicate this layer. Now, you have two hue layers. Moving on..
2 Make a new layer at burn or color burn. Fill it with #21C8FF. With the eraser tool, carefully erase the parts of this layer that is covering your flower(s).
Done! Both results might now be the same. But close enough. That was the only way I can translate it to PSP. I'm sorry if it may not work. This tutorial was originally created for PS anyway.
Good Luck! Comments are ♥
