Hyperstereo refers to using a larger than normal base, or separation between the lenses taking the left and right images. Usually this is obtained by using either two cameras widely separated, or by separate shots made by the same camera tens or even hundreds of feet apart. This can give a stereo effect to distant objects which would not normally display much. When shooting a hyperstereo pair, you should bear the following in mind:
1. As a guideline, use a separation of approximately 1/50 of the distance to your main subject.
2. Try to take both photos from the same "level" - avoid vertical changes between photos.
3. Unlike normal stereo, avoid foreground objects as much as possible - they can be very distracting
4. You will need some method to synchronize the framing of the two images. Use registration marks in the viewfinder, distant objects at the edge or center of the frame, etc. to adjust both images within the view-finder.
5. You may find it useful to switch to manual exposure to make sure both exposures are the same.
6. Select interesting subjects, suitable
for hyper-stereo images, such as mountain scenes, city scenes taken from opposite
sides of a tall building etc.
