Photosynthesis - Simultaneous dual-lens photography for iPhone
Show HN: iPhone app takes simultaneous images from 2 lenses, fuses into 1 photo
Photosynthesis is an innovative iPhone camera app that captures images from two lenses at once and fuses them into a single high-resolution photo. It combines the fine detail of the telephoto lens with the wider angle of the main camera, giving you real optical detail without any generative AI. Perfect for concerts, events, and any situation where you want both detail and context, Photosynthesis offers unlimited free capture and editing, with optional subscription for unlimited exports and professional formats like PSD.
Each capture fires two lenses at once then combines the results into one high-res photo, giving real optical detail with no generative AI.

The principle is similar to foveated imaging [1].
Recently, Samsung introduced the ISOCELL platform which allows to select the area which will be recorded at higher resolution compared to other regions.
There can be all sorts of different applications build around such as extracting higher resolution of text regions, etc [2].
Of course, the lens needs to support this resolution but I think that will be default in the mid-term future.

Pretty cool -- I built see ya' an app which allows you to connect N number of phones locally, and use one phone as the view finder + shutter, and the other(s) as the dedicated camera. I'm just using Apples native API, so it'll connect over bluetooth, wifi, direct, whatever pretty seamlessly. I don't collect any data, and it's 100% free.

It’s weird, because the center of the image will be more detailed, so how are they dealing with the “grid of pixels” that is on the display. Are they doubling up the wide angle.
“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.“
Reminds me of the old 3d cameras that took two photos at once through 2 lenses (on film)
