# Photosynthesis Source: [https://photosynthesis.camera/](https://photosynthesis.camera/)  ##  Zoom and enhance\.For real this time\. **An innovative camera app for iPhone\.** Each capture fires two lenses at once then combines the results into one high\-res photo, giving real optical detail with no generative AI\. **Upgrade your camera without upgrading your phone\.**  Standard zoom  [https://photosynthesis.camera/#proof](https://photosynthesis.camera/#proof)  Standard zoom Tap the magnifier to zoom in on the enhanced detail, then drag the slider to compare\.the best of both lenses ## Have your cake and eat it 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\. DETAIL FROM A DISTANCE ## 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\.  Standard zoom  Standard zoom ## 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\.  Standard zoom GALLERY ## Shot on iPhone\. Shot on Photosynthesis\.

Standard zoom Just look at that architecture\.  Standard zoom Chalkboard, you say? How it works ## 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\. The overlaid brackets show the location of the more detailed lens within your shot\.### 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\. All two\-lens iPhones benefit from the 1 \+ 0\.5x pairing, while only three\-lens \(‘Pro’\) iPhones with an optical zoom lens have both options\. In the app ## 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\.

Is the detail created by AI?There is no generative AI use in Photosynthesis\. We do use machine learning to calculate the best alignment and colour match between the lens captures, but every pixel of detail comes from a photo taken by your camera\. Why can’t I zoom in the viewfinder?Photosynthesis is designed to capture the most detail possible for every photo, without compromising with digital zoom\. Keeping the image ‘zoomed out’ helps to frame your subject correctly for the full set of lenses\. You can then focus in by cropping the photo once it has been processed\. Can I set focus manually?The app defaults to focus in the centre of the viewfinder to optimise for the alignment of both lenses\. A manual focus control would fight against this alignment\. Does it work up close?Because the lenses are physically separate on your phone, the closer you are to the subject, the harder the two photos are to align\. If they don’t align properly, you can always export the image from each lens on its own\. Where are my photos saved?Every photo is kept inside the app so nothing is lost while the app is still installed\. You can optionally backup to iCloud and/or a folder of your choosing, and you can auto\-export every photo to the Photos app, as well as manually export in a number of different formats\.
