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.

To be honest, I wouldn't be surprised if Apple isn't already doing this and just doesn't say so explicitly. There is a crazy amount of image processing going on behind the scenes in each smartphone photo. Would be interesting to compare a photo taken with the native camera app and photosynthesis to compare. I'm assuming your demo images on your site are the raw and processed images from your app that don't go through Apple's "secret sauce" processing pipeline.

Somewhat related... I made an indie app called TwinCam which combines front-and-back camera images to create a combined selfie. Free. No strings attached. Cheers!

Neat work, but the free tier lets you export 3 images a month and the alternative is a subscription? No thanks.

It would have been nicer if the examples wouldn't have been digitally altered to exaggerate the results. For instance, the center of the third photo has been intentionally blurred in the "standard photo" version.
The fact that they have to resort to manipulation to sell their product tells me that they are not trustworthy and that their product is probably underwhelming.

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)

I just assumed this was what all phones with multiple rear cameras were doing, is it not? What are the multiple cameras for other than that?

subscription camera app seems like peak comedy to me

If it works, Apple copies it soon enough...

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.

I cannot see a meaningful difference at all in any of the example photos, so not really seeing what the point of this is.
