4.2 Using the GigaPan to Control Bracketing Exposure

This configuration will have the GigaPan perform the necessary shutter length to correctly
expose bracketed images. It assumes you know that your center or 0 exposure point is. It
will then fire a sequence of shots at 0, -EV stops, and +EV stops in increasing time values.
For example, it will shoot 0, -2, -1, +1, and +2, when 5 brackets and ±1 EV stops is selected.
1. Configure you equipment to do bracketing exposure
Configure the GigaPan using the following settings:
In the "Options" menu, configure your settings as follows...
1. Brackets: Set to desired number of levels (3, 5, 7, or 9)
2. EV Step Size: set to desired step size (0.3, 0.7, 1.0, 1.3, 1.7, 2.0)
3. Set Time/Exposure to your 0 EV exposure shutter speed value
4. In the "Expert Menu", set "Shutter Length" to Exposure (bulb)
Configure the camera using the following settings:
1. Set the camera to shoot singe shots
2. Set shutter to bulb mode by turning the dial to "B" or shutter speed to "B"
3. Set your aperture to your 0 EV exposure value. Might need an ND filter so as to
not overexpose.
2. Configure the GigaPan to take a panorama. While taking the panorama, the GigaPan will
take multiple exposures at each location in the bracket sequence. If the camera has trouble
writing the images to the card before the next image position, increase the bracket delay
in the "Expert Options" menu.
3. Make sure that each exposure is under (slower) than the camera's recommended shutter
setting for bulb mode (recommended slower than 1/10s). However, some modern DSLRs
can go as fast as 1/50s.
