Section 1: Tips for taking photographs intended for HDR processing

Photographing a high contrast scene requires taking several exposures in order to capture

information in both the brightest highlights and deepest shadows of the scene.

Photographs can be made with digital or film-based cameras. The only requirement is that the

exposure can be adjusted when taking pictures. If you use a film-based camera, you will need to

scan them into your computer before processing them. Photomatix Pro can merge image files

saved in JPEG, 8-bit or 16-bit TIFF, and PSD formats. It also supports RAW files of several

camera models.

There are two general recommendations for creating differently exposed source images:

1) Make sure to take a sufficient number of exposures to properly cover the dynamic

range of the scene, from the darkest shadows to the brightest highlights.

2) Use a tripod whenever possible. Photomatix Pro incorporates Image Alignment

functions, but using a tripod is still recommended.

1.1 Automatic Exposure Bracketing (AEB)

 Shoot with available light whenever possible. The flash may try to balance the exposure

of all the images, when a range of exposures is the goal.

 Select a low ISO to minimize image noise.

 Select Continuous shooting mode on the camera’s drive setting (Note: Continuous

shooting mode may not always be the best strategy because camera shake may build

up. We recommend using a method that ensures the least possible shake for each

single shot, e.g. mirror lock-up functionality, if available). Consult your camera manual

for model-specific instructions on using this setting.

 If possible, use the camera’s self-timer setting, or a cable release to minimize camera

shake.

 Set your camera to Aperture priority (A setting) so that only the shutter speed varies

between the exposures.

 Set the camera to Auto Exposure Bracketing (AEB), which takes several photographs of

a scene in a row: one at the proper exposure, one or more underexposed, and one or

more overexposed.

o Most cameras allow you to select the amount of over/under exposure in one-third

or one-half increments. The suggested exposure increment is +/- 2 for optimal

exposure range. If your camera does not offer +/- 2 exposure increments, select

the maximum possible. Consult the camera manual for model-specific

instructions on choosing this setting.
