Real IES Mobile is a simple utility for light designers, game developers, 3D and VFX artists.
With Real IES you can edit a super-imposed light, composited on your phone's camera image*.

Edit the light as you prefer then save the file. Real HDR Mobile will create a .rim file to be processed in Real IES desktop (both on PC and Mac). Fine tune your light settings and export a beautifully custom photometric file for your creations.

*the camera image is used for visualization only. No images are collected or shared anywhere.
