The app, which supports 1x + zoom and 1x + 0.5x pairings, offers a 14-day free trial followed by a subscription, and exports include layered PSD and spatial photo formats.", "body_md": "Zoom and enhance. For real this time.\n\n**An innovative camera app for iPhone.**\n\nEach capture fires two lenses at once then combines the results into one high-res photo,\ngiving real optical detail with no generative AI.\n\n**Upgrade your camera without upgrading your phone.**\n\nNearly every iPhone carries multiple lenses on the back, so why not use them together?\n\nPhotosynthesis 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.\n\nFor 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.\n\nPhotosynthesis is perfect for concerts and other live events, giving you the clearest view of your subject without compromising on the atmosphere.\n\nThe 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.\n\nUntil now, you’ve had to choose between detail and field of view. Now you can have both in one seamless photo.\n\nPhotosynthesis 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.\n\nEvery pixel Photosynthesis delivers is captured by your camera, with no generative AI use whatsoever.\n\nThe centre glow highlights the otherwise seamless border between the lenses.\n\nFrom awkward selfies in your kitchen ...\n\n... to the moments you never want to forget ...\n\n... capture every pixel of detail your phone can deliver.\n\nTurn a great view into an even greater photo.\n\nSome test shots are more interesting than others.\n\nWho doesn’t love a photo of a chalkboard?\n\nThis one was quite fun, I’ll admit.\n\nJust look at that architecture.\n\nChalkboard, you say?\n\nOne 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.\n\nFrame your subject inside the brackets that indicate the more detailed lens.\n\nPhotosynthesis captures from multiple lenses simultaneously, allowing for a combined capture even during motion.\n\nAlignment and colour are matched automatically between lenses, so you get the wide framing with the inner lens’s real optical detail.\n\nThe brackets over the viewfinder indicate the area covered by the more detailed lens. Frame your subject inside them to capture the best detail.\n\nThe 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.\n\nApply 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.\n\nExport 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.\n\nUse our custom Photosynthesis file to export and re-import a photo to Photosynthesis without losing any layers or editing capabilities.\n\nEverything is unlocked for the first 14 days. Following this, you can still capture and edit as many photos as you like for free.\n\nEverything unlocked in one reasonably-priced subscription.", "url": "https://wpnews.pro/news/show-hn-iphone-app-takes-simultaneous-images-from-2-lenses-fuses-into-1-photo", "canonical_source": "https://photosynthesis.camera", "published_at": "2026-08-08 22:47:10+00:00", "updated_at": "2026-08-11 17:13:40.601743+00:00", "lang": "en", "topics": ["ai-products", "computer-vision"], "entities": ["Photosynthesis", "iPhone"], "alternates": {"html": "https://wpnews.pro/news/show-hn-iphone-app-takes-simultaneous-images-from-2-lenses-fuses-into-1-photo", "markdown": "https://wpnews.pro/news/show-hn-iphone-app-takes-simultaneous-images-from-2-lenses-fuses-into-1-photo.md", "text": "https://wpnews.pro/news/show-hn-iphone-app-takes-simultaneous-images-from-2-lenses-fuses-into-1-photo.txt", "jsonld": "https://wpnews.pro/news/show-hn-iphone-app-takes-simultaneous-images-from-2-lenses-fuses-into-1-photo.jsonld"}}
