Nearly every iPhone carries multiple lenses on the back, so why not use them together?
Photosynthesis combines the fine detail of the zoom lens with the wider angle of the main, keeping the best parts of each to give the best photos your iPhone can deliver.
For iPhones without an optical zoom lens, Photosynthesis delivers an equally impressive experience of combining the detail of the main camera with the breadth of the ultra-wide. This is also available on Pro iPhones with zoom.
Front row detail with crowd context
Photosynthesis is perfect for concerts and other live events, giving you the clearest view of your subject without compromising on the atmosphere.
The 1x + Zoom pairing gives an incredible upgrade in quality to the centre of your photo, while 1x + 0.5x lets you add wider context to your photo without compromising on detail.
Real detail without compromise
Until now, you’ve had to choose between detail and field of view. Now you can have both in one seamless photo.
Photosynthesis gives you the freedom to capture the widest field of view possible without losing any detail if you decide to crop or re-frame later.
Every pixel Photosynthesis delivers is captured by your camera, with no generative AI use whatsoever.

Some test shots are more interesting than others.
Who doesn’t love a photo of a chalkboard?
This one was quite fun, I’ll admit.
Just look at that architecture.
Chalkboard, you say?
Simply press the shutter.
Let the app do the rest.
One press of the shutter captures two of your iPhone’s lenses together. The app then combines them into a single high-res photo, keeping the best detail possible for each part of the photo, using only real optical detail captured by each lens, with no generative AI.
Line up the shot
Frame your subject inside the brackets that indicate the more detailed lens.
Press the shutter
Photosynthesis captures from multiple lenses simultaneously, allowing for a combined capture even during motion.
Marvel at the results
Alignment and colour are matched automatically between lenses, so you get the wide framing with the inner lens’s real optical detail.
A camera and custom editor built around two-lens photos
Easy-to-understand framing
The brackets over the viewfinder indicate the area covered by the more detailed lens. Frame your subject inside them to capture the best detail.
The best of both lenses
The app processes both images, matching their alignment and colour, to deliver a single photo combining the larger area of the outer lens with the real optical detail of the inner one.
A fully-functional editor
Apply filters, adjust the image manually, crop and rotate as standard, with an extra layer of editing tools designed for two-lens photos. You can tweak the alignment of the inner lens, and ‘paint’ over any errors to correct ghosting or doubled subjects.
Professional exports
Export the finished photo to your Photos library or any other app, with a number of formats including a layered Photoshop (PSD) document, spatial photo, side-by-side 3D, and more.
Use our custom Photosynthesis file to export and re-import a photo to Photosynthesis without losing any layers or editing capabilities.
