Other Apps
As good as the Photos app is, it is not a professional software and so it lacks many features that professionals would want. Apps like Adobe Photoshop, Adobe Lightroom, Affinity, Luminar and more are suited for professionals that need to edit pictures on a professional level. These apps offer layers, and tools that are specialized to create the best images possible but they also cost a lot of money and have a steep learning curve.
That is why I recommend the included Photos app on your Mac if you are a beginner or a casual user that is looking to enhance your pictures. The Photos app is great for casual users that don’t want to learn professional software or spend money on such software.
Conclusion
So, there you have it, editing pictures on your Mac is as easy as that. The Photos app is excellent if you want a quick edit to be done on your images. It can enhance any picture you have and is simple for anyone to get grips over it. Pick a picture and start experimenting with it, you will be an expert with the Photos app in no time.
