Capturing 3D Images—Introduction
Always carry a lens cloth and always check that your lens is clean before taking pictures.
Most of what you know about 2D photography also applies to 3D. For example, focus, exposure, white balance, and depth of field are the same.
As with 2D photography, there are few "rules" about composing 3D images. Everyone has a personal vision and breaking the so called rules in the pursuit of that vision is perfectly acceptable. However, there are things to consider when taking stereo images and we discuss them on the following pages.
Most twin-lens stereo cameras don't have a viewfinder. If you can't see the image on your monitor because the sun makes it look like a mirror, you need to shade it—perhaps with a hood loupe like this one from Hoodman (www.hoodmanusa.com
When venturing out to take photos, you should have a routine you follow. For example, the night before charge the camera's batteries, make sure the lenses are clean, and check that their is a memory card in the camera with enough room for the photos you plan to take and then some. Even better, take along a spare charged battery and memory card. If you use a tripod, make sure all of it's parts are there. When taking a longer trip, be sure to pack your charger and USB and HDMI cables so you can copy and display your images.
When using a twin-lens camera keep your fingers away from the lenses—and remember there are two of them. If you are not careful a finger can appear in one or both of the images in a stereo pair. Even worse, a fingerprint on the lens, if unnoticed and unremoved can ruin a vacation's worth of stereo images. To be safe, always carry a lens cloth with you.
