In this Photoshop exercise, I start with the combination of two grayscale images to show how variations in color, adjustment layers, blend modes, layer masks, layer styles, and accent images, can change the feeling of the overall composition so dramatically.
The photos used in this exercise are from left to right: Stormy Road by Ryan McGuire, untitled grayscale image of woman in cornfield by Kate Hliznitsova, Front view light bottle with golden cap isolated white floor by KamranAydinov / Freepik, and Person riding tractor surrounded by peoples photo by Cayetano Gil.
