There’s more to adjusting brightness then changing the black level yet that’s all this does. You can do better with the native iPhone photo editor in just a few seconds in a variety of ways by choosing the auto adjust, exposure or any one of the temperature/Drama or vivid. You may have to give the brightness a little slide but you’ll have better results than this. I don’t think this will make anyone happy unless they’re a total beginner and somehow the bottom dropped out of their native photo editor, adjustments don’t exist … which isn’t going to happen.
