Magic Light Master is an exposure tool with a built-in white balance and light meter, used to make your photos and video more balanced and colorful.
A number of different filters can be applied to both photos and videos, to enhance the effect.
In addition to that, you can also apply different types of filters to each of your images and videos, to get the most out of them.
With this app, you can measure the amount of light in the shot, with a built-in light meter, and use that information to place your subjects on the exposure graph, or to change the exposure parameters of your camera.
The app is compatible with the vast majority of digital cameras on the market.
