What Is a 3D Photographer?

Three-dimensional photography is a way of capturing an image with two different shots that combine together to create a holographic effect. Also known as stereo photography, 3D photos capture the same scene twice from slightly different position to create a cross-eye effect by tricking your brain into seeing a 3D image. These photographers have special techniques for setting up two simultaneous shots in the same position so that they have mastered the holographic effect their photos make when they are synchronized to perfection.

3D photographers take photos of a variety of subjects and objects which they enhance with their 3D technology and technique. The technique usually involves taking one photo and then moving slightly to the right, using a tripod so that you have the same level from the ground when you take the second image. When an object is closer to the photographer, they only move the camera a few inches to the right before taking the second photograph. For objects that are further away, the camera is moved a greater distance from the first shot to the right.

Scenes or images which contain a number of objects or subjects scattered throughout the depth of field tend to be better 3D photos than those with a "flat" background. The depth of field is defined by how the camera picks up both near and far objects in a photograph, which gives the 3D effect a greater depth. Images that feature some sort of perspective, like a highway, train tracks and telephone poles tend to work best, because the distance of the image is implied by the same object getting smaller and smaller the further away from the camera they are.

A 3D photographer knows her photos will best capture the 3D effect when the subjects in the image are relatively motionless. This is because the 3D image is not complete until you have taken two images in sync with one another. Getting your images in sync becomes more difficult to do once your subject has moved into a different position from the previous one. Some 3D photographers will mount two cameras together on the same tripod or camera mount so that their photos are synchronized to capture a subject in motion. They use the same shutter speed and aperture setting on each camera for each shot. Taking one shot after the other in rapid succession is necessary for capturing action shots in 3D.

Once you have the photos, you have two options for viewing the effect. One would be to tint the first image in blue and the second one in red. Then superimpose them to create a composite image. This technique requires the use of 3D glasses to see the hologram effect. Another technique is to place the two photos side by side and stare at the space in between them. If done properly, your eyes will begin to cross and converge on the emerging hologram. When you have merged the two images, bring both into focus and the 3D photo should pop out at you.
