Without a doubt one of the best photography apps that I have found. Not just for underwater photography but for photography in general. Great for beginners to intermediate and even advanced or semi-pro.
Exposure is key not only to producing a photograph but also to the expression of a photographers vision. Understanding the basics to reading a histogram may seem simple but it is one of the most misunderstood or overlooked tools provided with digital file capture.
This app provides a simple, easy to understand tutorial that will explain what information the histogram provides and how to understand this information to achieve the exposure that tells the story of your photograph.

Developer Response ,

Shimonf26, Can you please let us know what didn't work and why you feel it should not be in the app store?
The application has been fine for everyone else. It is NOT a scam.
It is a training application for Underwater Photographers to better understand the Histograms on the cameras.
Thanks for your feedback.
