Framing HDR Photographs
The edges of the image may be cropped out. The desired results may not be achieved if the
camera or subject move during shooting. Use of a tripod is recommended. Depending on
the scene, shadows may appear around bright objects or halos may appear around dark
objects; this effect can be reduced by adjusting the amount of smoothing.
