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.
Two images shot at night near Nijmegen
After this former cigar factory and it's associated house were set fire too twice, CCTV was set up. They use bright green lights. A good opportunity for me to take some shots.
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.
