PhotoExposure lets users explore the various items that control the exposure of an image. Buttons and sliders allow the user to manipulate scene brightness, shutter speed, aperture, ISO, and even the presence of neutral density filters. To maintain a proper balance, any change made by the user to one item will result in an equal and opposite change to another user-selectable item.

User's may also take a photo using their device and have the exposure settings transferred into the slider values, effectively turning their device into a reflected-light meter.

There are descriptions of typical scenes for many brightness levels, and users can add their own descriptions as well.

PhotoExposure is available on Apple iPhones and iPads.
