Correct. The apps I used allowed both Lidar and photometric modes (whereby you take like 200 pictures) and it stitches them together to create the 3D image. You then scale the image inside your printer software to the size desired, keeping the proportions constant. So while I have an iPhone Pro, I'm pretty sure this 2nd method is able to be performed with any reasonably new smartphone camera (wouldn't guarantee it, so check if anyone is interested, before buying the 3D printer.. ha).
I will say, it's easy enough that it's truly fun to play around with. I've had my printer now for like 4 days and so getting used to it, its software, the image capture and finding the best/easy-to-use 3D CAD software is a bit much.... but I'm just one of those guys that has to jump "all in" :-). The average person could have everything going in a day to just get a job done.
