Photosynthesis

Photosynthesis is an iPhone camera app that fires two of the phone's rear lenses at once and fuses the frames into a single high-resolution photo. Phone photography normally forces a choice: the zoom lens sees detail, the main or ultra-wide sees the whole scene, and one shot gives you only one of them. Here a single shutter press captures both, and the app matches their alignment and colour so the wide framing keeps the real optical detail of the inner lens. Brackets in the viewfinder mark what the sharper lens covers, and you can crop or re-frame later without giving that detail up.

The maker states that no generative AI is involved: machine learning only computes the alignment and colour match, and every pixel comes from the camera. A built-in editor adds filters, crop and two-lens tools for nudging alignment or painting out ghosting, with exports to layered PSD, spatial photo and side-by-side 3D. Every iPhone from the 11 onwards with two or three rear lenses is supported, two-lens models pairing main and ultra-wide while three-lens models can also pair in the zoom, and concerts and other live events are the pitched use case. Capture and in-app editing stay free with five exports a month, a subscription or a one-off lifetime unlock removes the limit, and the app is not out yet: the site is taking early-access applications ahead of a summer 2026 release.
