The user then simply needs to access the camera's HDR mode through the menu dial, set the camera up for the first shot, press the shutter, and off it goes. The internal sensors will then take three shots and combine them into a single HDR image.

Firstly, the standard correct exposure photograph is metered and exposed. The onboard sensors then independently calculate an overexposed image and an underexposed image.

Within seconds, the K20D and the K200D will have taken three separate photographs and will begin the process of merging them into a single HDR image. Control is limited as the only control the user has over the process is to decide whether the camera will expose the over and underexposed images at one or two stops above or below correct exposure.

Once all three photos are taken, the contrasting areas of the images are compared, balanced and combined into a single picture which displays a broader dynamic range than a conventional photograph, allowing for more evenly exposed images and a more natural look. With LiveView, the results can be instantly previewed, and the process repeated if necessary.

BE WARNED: Pentax's HDR capability is still strictly limited to still life or scenery photography only. If your subject is moving, it won’t work (unless you get everybody to stand really still).
