I know, I just don't think it's a huge jump from "take multiple photos over a 2s period from one camera and stack them" to "take several photos from discrete physical cameras and stack them". As a subscription of paid app I am not the target market for the person who made this, I agree with another person commenting in here that said they should be working for a phone manufacturer.
replyI’d argue the opposite. The geometry involved in reconciling photos from two separate lenses with different focal lengths is quite challenging. If you pay close attention you will see some differences in the before/after samples in the site (for example the ear in that kitchen selfie).
replyThe math is surely more complex than aligning same-lens photography even when you consider the change in angle and perspective between two shots from the same lens.
Not really. Whether you have two different lenses or the same lenses with some offset from hand movement you need to accurately model the lens(es). Once you can do that for one lens you can just as easily do it for two - it's just more variables to optimize, not a fundamentally harder problem. Panorama software has supported images from different lenses since forever.
