It??™s important to use Aperture Priority mode when shooting a series of photos for HDR,
so the depth of field and resulting focus doesn??™t change from one photo to the next.
If your camera doesn??™t have a bracket mode, then you??™ll have to get a little more creative.
You can bracket the photo yourself by taking the first picture at normal exposure, then using
the exposure compensation dial (usually marked with a plus/minus symbol) to underexpose and
overexpose subsequent images. Take a series of shots with the exposure control set to ??“1, ??“2, ??“3,
+1, +2, and +3, for example. Throughout the process, remember to be careful not to move the
camera or each shot won??™t be aligned properly.
There are a variety of programs available that are designed to combine HDR photos. Adobe
Photoshop CS2, for example, has an HDR feature. So does Ulead PhotoImpact. There are also
some stand-alone HDR utilities out there. If you want to try something a little less expensive than
Photoshop, you can download the free trial version of Photomatix Pro from www.hdrsoft.com/.
There??™s no time limit on how long you can use Photomatix, but it does inscribe a watermark
across each of your photos unless you pay $99 for the full license.
