10 Dynamic Photo HDR

2 Capturing HDR images

2.1 Preparation

The basic idea to create HDR image with your digital camera is to take few shots of the same scene,

each with different exposure.

This can be done by manually changing the speed/aperture, or, better in most digital cameras simply

using Exposure Compensation (EV) settings.

Note: Before you start shooting, read the next two chapters that will explain what scene works best

and what exposures you should take.

Few cameras also have Automatic Exposure Bracketing feature, that even more simplifies the process

• it automatically takes three shots, each with different exposure.

Here are some examples of different way EV or AEB can be set on few cameras.

Unfortunately most consumer cameras that have AEB don't allow for more than +/- 1 EV in the Auto-

bracketing mode, very often you will need to use manual EV that usually is in -2 - 2 EV range.

Example of AEB in short range -1/+1 EV

Some cameras have EV settings buried deep in the Menu structure, which is hard to operate, some

other have it easily accessible with a button.

Obviously, the best way is to capture the images on a tripod. However the aligning feature will allow

you to take pictures without tripod, then align them in the software.
