Fuji Real 3D camera have two commands that let you change the baseline even though the lenses remain fixed. They do so by taking both photos in a stereo pair with the left lens. The second photo is taken manually just like the first one or automatically at a specified interval. No matter which approach you use, the two photos are combined into a single MPO file and can be viewed just like any other pair. These modes are used when photographing close-ups or distant scenes where you need to change the baseline anywhere from a half-inch or several feet. Provided nothing in the scene is moving, you can take as much time as necessary to set up the second shot.

Individ Shutter 3D

This setting is used when you want to capture a stereo pair by manually taking each image separately.
  1. Turn the Mode dial on the back of the camera to A3D. If using this mode for macro photography press the 3D button to switch to 2D, then press the macro point on the Selector button marked with a flower blossom icon. When macro mode is on, the same icon is displayed on the monitor.
  2. With the camera on, press Menu to display the shooting menu, highlight SHOOTING MODE and press the right point on the Selector button.
  3. Press the up or down button on the Selector button to highlight the INDIVID. SHUTTER 3D and press OK to return to the shooting menu.
  4. Press the down button on the Selector button to highlight TURN, then press the right point to display choices.
  5. Press the up or down button on the Selector button to highlight the direction in which you want to capture images (the default is 1 -> 2) then press OK to return to the shooting menu.
  6. Press BACK to hide the menu and two camera icons numbered 1 and 2 (for left and right image) are displayed on the monitor. The number of the image to be captured next is highlighted.
  7. Take the first shot (the camera uses the left lens) and the captured image is displayed semi transparently on the monitor so you can align the second shot in live view. The icon for the second shot is highlighted. (To exit at this point without taking the second shot, press BACK or turn off the camera.)
  8. Using the first shot as a guide, reposition the camera's left lens and take the second shot in the stereo pair.
  9. Take the second picture in the pair and review the results in 3D on the monitor. You might try switching to playback mode and using the parallax control to adjust the stereo window as described in the Placing the Stereo Window section earlier in this chapter.
ABOUT THESE SETTINGS

The step-by-step instruction in this section refer to the Fuji W3. The W1 has the same settings but you access them differently. Refer to your camera manual for detailed instructions.

After you follow these instructions to make your settings, you only have to select the mode the next time unless you want to change settings. Your changes are remembered even if you turn the camera off and then back on.

 
ALIGNMENT

When you capture two images in a stereo pair separately, the images are likely to have alignment problems. These can be corrected using StereoPhoto Maker as discussed in Chapter 4.

Interval 3D Shooting

This setting is ideal when capturing stereo pairs of distant scenes from a moving vehicle such as a plane, train or automobile. You take the first picture and the second is taken automatically after a specified period up to 10 seconds long. (See Calculating a Stereo Interval on page 85.) One of the best things about this procedure is you don't have to press the shutter button to take the second picture. You can therefore really brace yourself so the camera loves as little as possible between shots.
  1. Turn the Mode dial on the back of the camera to A3D.
  2. With the camera on, press Menu to display the shooting menu, highlight SHOOTING MODE and press the right point on the Selector button.
  3. Press the up or down button on the Selector button to highlight the INTERVAL 3D SHOOTING and press OK to return to the shooting menu.
  4. Press the up or down button on the Selector button to highlight the 3D INTERVAL TIME and press the right point to display a list of times.
  5. Press the up or down button on the Selector button to highlight a time (Min is about 0.8 seconds) then press OK to return to the shooting menu. Faster speeds are best for closer subjects, or when photographing from faster-moving vehicles such as airplanes. The best results are achieved if the baseline is between 1/30th and 1/50th of the distance to the subject. The images may be hard to fuse if the parallax between the two shots is too great or if there is a foreground object between the camera and subject.
  6. Press the down button on the Selector button to highlight TURN, then press the right point to display choices.
  7. Press the up or down button on the Selector button to highlight the direction in which you want to capture images (the default is 1 -> 2) then press OK to return to the shooting menu.
  8. Press BACK to hide the menu and two camera icons numbered 1 and 2 (for left and right image) are displayed on the monitor. The number of the image to be captured next is highlighted.
  9. Hold the camera as steady as possible, pointed perpendicular to the direction of travel, and press the shutter button to take the first shot. A timer for the interval time you selected is displayed and, as you continue holding the camera in the same position, the second shot is taken when the timer reaches zero. You can't use any camera control while the timer is active and if you turn off the camera before the second shot is taken, no picture will be recorded.

This stereo pair, shown as here an anaglyph, was taken out of the window of an airliner on it's descent into LAX. During descents like this the engines are throttled back and the plane is almost gliding so turbulence and vibrations are often at a minimum.

WHY TURN?

One application of the TURN command is when photographing out of the right side of a vehicle such as an airplane. This is discussed in the section on Hyperstereo.
 
REMEMBER THE RULE?

You may not be able to fuse the images if the parallax between the two positions is too great. The best results will be achieved if the distance the camera is moved between the two shots is between 1/30th and 1/50th of the distance to the subject. When doing macro photography the baseline is often less than an inch.
