At iPhonePhotoGuy, we test lots of apps. It’s our opinion that serious photographers should avail themselves of at least one of the many third-party camera apps that give more control over the photographic process. FilmicPro, ProShot and Halide Camera come to mind.
But if you want to stick with the free Camera app that Apple includes in iOS you can still do some advanced tweaking of your images.
Most importantly, you can adjust exposure using the iOS Camera app.
When you are preparing to make a photograph, tap the part of the frame that you want to make most visible. This will cause a yellow box to appear around the spot you select. If you see an area that is too dark, tapping here will make things brighter. It’s sort of an automatic setting that adjusts the image the way Camera app sees fit.
By long pressing on that spot, you can even set an AF/Exposure lock – which means that even if you recompose the scene, the resulting image will be focused and exposed according to the spot you previously selected.
Tap anywhere on the screen outside the exposure box to turn off AE/AF Lock.
See if this meets your needs, then you can decide on investing in a third-party app.
