Light for iPhone and iPod Touch
Windows Gobo Selection Screen

Light can be added to a scene where none existed before just as if you were adding light at the time of photography.

Realistic lighting and shadow is introduced using digital versions of the gobo library created by Gamproducts. For more information on Gamproducts gobos, please visit their website at

Gobos, or patterns, are widely used by lighting designers in theatre, film, photography and television to create atmosphere, project scenery, and generally enhance the visual impact of their lighting. Normally used in front of lights during photography, these same exact patterns can be applied digitally to the entire image or inside a selected area. Gobos from the Gamproducts collection are included with Light and are arranged into the following categories: Breakups, Foliage, Lights, Sky and Windows.

Donít settle for bland photos. Spice up your images with Light, just like Hollywood cameraman and photographers do. See the Light!

  2. Drag the Position slider to place the light on a particular portion of the image. With the Lum (Luminance) button selected, a high Position value places the light in the brighter areas of the image while a low Position value places light in the darker areas of the image.
