Illuminant

Create soft and balanced off-camera lighting.
Give your photographs a light boost or add some soft fill light to balance your lighting ratio.
Use catch light patterns to create reflections in the eyes of your subjects.
Use the built-in camera to measure the tonal color of the existing light and match the screen color to the environment for color matched photographs.

You can also choose from the color scene presets to set the light color anywhere from Sunset to Skylight.

Fine tune controls allow to you adjust the color and luminosity as you please.

Best results are obtained with an iPad, but the app can also be used with an iPhone or iPod Touch as a photographic light boost in your pocket.
