How to Take Stereo 3D Pictures With Your Cell Phone - A Simple Step by Step Guide
Download the free 3DSteroid app from the Google Play Store. You can alternatively download the 3DSteroidPro app which isn't free but includes automatic alignment, discussed below. Open the app and select "Camera" from the list on the bottom of the screen.
Use the round shutter button to take a photo of a stationary scene or subject. Then, before moving, slide the camera a little to the right and take another photo. The distance you move sideways should be dependent on the distance between you and the nearest subject. For instance, if the nearest person or object is only a few feet away, you should probably only move about a centimeter or else risk getting too much deviance between images which is irreparable. If you're taking a broad, landscape type photo with objects more than 30 feet away, you should probably move it a few inches in order to get enough depth. Please not that even if you're taking a picture of a distant subject, if there is something in the foreground you'll need to decrease the width between shots accordingly. Experiment with different distances and widths to get a feel for it.
If you have 3DSteroidPro, the paid version of the app, then upon taking both pictures the software will automatically align them. If you have the free version mentioned in step one, then you will need to do the alignment yourself which is almost always necessary. Select "Edit" from the options at the bottom and use the up, down, left, right and rotate buttons to make the image as flush as possible. Due to the nature of 3D images only one portion of the image can be flush at a time, and it's generally best to aim for the middle ground.
Make sure that the left image is on the left and the right image is on the right, otherwise the depth will be inverted. If it is, press the "Swap" button at the bottom. Press the "Stereo" button to save the image in various formats such as anaglyph for either red/blue or yellow/blue glasses, side by side for either cross eyed or parralel free viewing, wiggle for 2D motion and panorama for use with a VR viewer. Press the three dotted menu button, click save, choose your resolution and your 3D image is ready to share!
