Project Indigo

Adobe Research · Computational photography camera app
Experimental iOS only

A research project from Adobe Fellow Marc Levoy (creator of Google's computational photography pipeline) and Florian Kainz. Captures up to 32 frames per photo for drastically reduced noise and better highlight recovery. Deliberately avoids the "smartphone look" of over-sharpening and over-saturation. Outputs computational RAW files — not just JPEGs — that benefit from the multi-frame capture. Android version planned.
