It's focus stacking so basically just compensating for the way macro lenses and large apertures work. There's nothing artificial about it, the software is just layering the sharpest parts into the photo. It's a common technique, heavily used for things like astro photography and landscape photography as well. https://www.canon.co.uk/get-inspired/tips-and-techniques/foc...

Can you leverage focus stacking on a mobile camera? I poked around a bit for relevant apps but didn’t see anything credible.

My understanding is that modern mobile phone cameras do heaps of "stacking" across multiple axes focus, exposure, time etc to compose a photo that saves onto your phone. I believe its one of the reasons for the multiple cameras on most flagship phones, and then each of them might take many "photos" or runs of data from their sensors per "photo" you take. id love to see a good writeup of the process, but my gut says exactly what they do under the hood would be pretty "trade secret"ie.

Can any mobile cameras focus close enough to be useful for macro? Maybe you can buy a third party add-on lens?
