1.2 How to Take Photos for HDR Processing
Taking photos for HDR is easy. All it takes is a different mindset than for traditional photography, which
emphasizes taking and editing a single photo, independent from any others.
Instead of taking a single exposure of a scene, for HDR you take at least 3 exposures: one optimized for midrange
tones (as normal), plus one optimized for highlights and one optimized for shadows. This strategy for capturing
more of a scene’s true dynamic range, with exposures above and below a standard exposure, is called “exposure
bracketing”.
The resulting “bracketed set” of photos contains, as a group, more complete and true exposure information
than any single image capture can possibly contain. The purpose of HDR software like Photomatix Essentials
is to artfully combine this bracketed set into a single image, to achieve more faithful realism, or heightened
realism, or artistic effect.
But these artistic choices come later. The first step is capturing good bracketed sets.
1.3 Set Up Your Camera
HDR photography requires that you set up your camera a bit differently than normal:
• Set your camera to Aperture Priority (“A” setting) so that only the shutter speed varies between the exposures.
• Select a low ISO, such as ISO 100 or lower.
• Turn off the flash. The flash may try to balance the exposure of all the images, when the goal is a range of
exposures.
• A tripod is typically recommended, but is not required, as Photomatix Essentials includes options to
automatically align hand-held bracketed sets.
DSLR cameras and some compact digital cameras offer Automatic
Exposure Bracketing (AEB). This enables you to automatically take three
or more exposures in a row: one at the proper exposure, one or more
underexposed, and one or more overexposed. Follow these steps if your
camera offers an AEB mode:
• Select the Continuous Shooting mode on the camera’s drive setting.
Consult your camera manual for model-specific instructions for using
this setting.
• Set the camera to Auto Exposure Bracketing (AEB)
• If possible, use the camera’s self-timer setting, a remote control or a
cable release to minimize camera shake.
• Set the exposure increment to +/- 2 EV for optimal exposure range. If
your camera does not offer +/- 2 EV exposure increments, select the
maximum possible. Consult your camera’s manual for model-specific
instructions for choosing this setting.

Bracketing (AEB) with various camera models on the page here:
