I have tweaked and layered and created presets from scratch for years and am proud to share these two base presets with you!
The Color preset has two AI smart masks to mask out the subject and the background in order to provide separation. Bothe the Subject and the Background have been tweaked to my “go-to” settings.
The Black and White preset has one vignette mask.
Please remember that no preset is a one-click-wonder! The first things to try are the correct exposure & white balance on the overall image & then again for each mask. The color preset does have added Grain which can be adjusted to your liking (just like all other settings).
