1.2 Manual Exposure Bracketing for DSLR cameras

In scenes with extreme differences between light and dark detail, manual exposure bracketing

over a greater exposure value range may provide better source images than Auto Exposure

Bracketing. t is the only option if your camera does not offer automatic bracketing over a wide

enough range to cover your scene. The following suggestions will help you to take optimal

pictures using manual exposure bracketing.

 Choose a low ISO to minimize noise.

 Keep a constant aperture and ISO. Control image exposure by changing the shutter

speed in full-stop increments. When taking pictures, use either the A or M setting,

Either of which will allow you to fix the aperture.

 Shoot a series of images starting with your brightest image elements (highlights)

being slightly underexposed (see Figure 2.1 below) to the darkest image elements

(shadows) being slightly overexposed (see Figure 2.2 below). You may or may not

want or need to use every exposure in the series for HDR processing, but it is easier

to delete a picture at processing time than to return to a location to take additional

images. Experiment with different combinations of the bracketed source images in

Photomatix Pro to achieve your desired effect.

 Check your DSLR's Histogram preview in playback mode to ensure that you have

captured the entire tonal range of the image. You should have at least one picture

without a large peak at the left side of the histogram and one picture without a large

peak at the right side of the image.

 Use self-timer mode and mirror lock-up, or a cable release and mirror lock-up

options, if available. These will help minimize any camera shake, especially for

exposures slower than 1/15 second.

elements (highlights) underexposed.
