All 3 is in the app! It's a much harder challenge to deal with the parallax and other artefacts that come up from combining 3 lenses, so that particular feature is launching in beta.

That is something I want to look at post-1.0-launch.

Nothing in the app is gated from day 1, you get 14 days of unlimited use before the choice of free vs paid is even presented, with no need to sign up for an official "free trial", so you have a good amount of time to make your min

That looks insane, definitely a trypophobia trigger!

There is zero lock-in with the files being saved - you can export from the app in HEIC/PNG/JPEG as well as PSD and spatial/SBS 3D. The format the website calls the 'Photosynthesis' file is an HEIC so even if you exp

I believe that's a similar idea to Apple's Deep Fusion which also takes multiple frames from the same lens then intelligently combines them for higher detail. As ipsum2 said below, that's different to Photosynthesis, which ca

As dole alluded to below, I have been going back and forth in balancing the quality of the example pictures with the data load. I've pushed an update to the site now that weighs much more towards quality for this exact reason! But you&

That's really interesting - the colour match attempts to find the best match between the two lens outputs, which frequently results in them 'meeting in the middle'. You can then manually adjust the output of each lens within

I believe that's true for most/all night capture, but they take sequential frames from the same lens rather than combining multiple lenses.

Thank you, I think I've seen that from reviews for every paid app I've come across - still, happy to take feedback!

I'm scaling the wider 'outer' image using Core Graphics 'CGInterpolationQuality' to avoid blocky pixellation, then feathering the seam between the two lens outputs so the transition isn't jarring. I didn't

I think this may be due to an issue I've had with loading the full res zoom images on the website, I've been going back and forth trying to balance the loading times and stress on the browser with clarity of the images. Working on

Thank you! I'm quite a new dev so honestly I don't know where to pitch the free tier, and I'm not above changing it. Do you have any suggestions for the free tier?

Thank you very much, that's really appreciated! Just added all the new sign-ups to the TestFlight, looking forward to hearing what you all think.
