Fun and creativity. Ultimately, you should learn photo editing just because it can be a super fun way to express yourself & improve the photos of your choice. Photo editing, in a sense, is all about imagining a more vibrant world, with bette texture and light and shadow balance. You can take a look at a Beautiful Bizarre Magazine issue for some of the more artsy, surreal examples of where a photo editing course can take you. But also bear in mind that if you’re editing something more realistic, then the nature of the challenge is quite the opposite: You need to try your best to resemble the way the human eye sees.
