In macOS 10.13 High Sierra, Apple significantly enhanced the editing capabilities of Photos on your Mac, adding tools for adjusting specific colors, fine-tuning color and contrast via curves, and even focusing an image with vignetting. But it still lacks many features found in other image editors, including applying a filter to an arbitrary portion of an image and adding text to an image. Happily, the latest version of Photos brings back a feature from iPhoto that lets you edit any image with any editor on your Mac. Just Control- or right-click a photo and choose Edit With > YourFavoriteImageEditor, and the photo opens in that app. Make your changes, and when you save, those changes are reflected in the version in Photos. This is an Awesome if you ask me..... I can't wait to try this in Photoshop?
