Using Photoshop, you can merge multiple images together, completely change the color palette of an image, and fix parts of an image to make them better (particularly portraits). It has way too many features, but once you master the basics, Photoshop gives you the tools to turn your imagination into reality. Photoshop is a massive, complex application with over two decades of consistent updates. If you want to learn how to edit a picture on Mac devices then use this app. In fact, you can’t edit RAW images in Photoshop without the Camera RAW plugin. Pixelmator is one of the best iPhoto replacement tools available for Photos for MAC. Once you’re done with that, you can import the image in Photoshop to kick things up a notch. You can use Lightroom to bring out all of the details from a RAW image file or to enhance an image aesthetically (to fix colors and saturation levels). Photoshop is famous for its advanced selection tools, complex layer system, and infinitely customizable brushes. Photoshop is designed specifically for image manipulation and enhancement.
You can think of it as Lightroom’s bigger brother. Photoshop is a different kind of photo editor.
