3D photography, phone pics, at night
I searched for stereo photography in the App Store and found a simple app that let's you take two photos in succession. The first one leaves a ghost so you can allign the second. There is freedom in spacing the two images, by moving the phone an uncertain amount between the two takes.
Here are some images I took at night.
The app is not perfect. It corrects for the angle of the phone during the second take, but it always shifts it a bit. On the last step, you can correct this. Also, when finished, the is shows the two images too small. I wish it would let the user correct the two images while looking through a viewer.
I'm not sure if there is a payed version, but I use the app outdoors, away from wifi, and I blocked it's access to the mobile network, which is a thorough add blocker.
