Does more than name implies
I am retired from the graphic arts, with 25 years of experience producing print advertising. Photoshop was a valued part of my tool kit and I was skeptical that an iPad app could provide serious image editing. But then I tried Snapseed and found that it could improve upon many kinds of image problems. After reading good reviews about Instaflash Pro, I tried it for its dark area adjustment. Oh yes, it does do that but so much more. After months of use on many different kinds of images, it has become my "go to" app. It can bring out an amazing amount of beauty hidden within even properly exposed photos. The name does not do it justice, as this app goes way beyond lighting enhancement. If you want more control than what presets can give you, this is the one to use.
