Hdr photography has taken it’s place in the photographic world. I have been experimenting with HDR photography since it’s infancy. There were plenty of purists, and still are that believe HDR is “cheating”. In some aspects I agree, but, like it or not, the digital age is here, and it’s not going anywhere. If you are not familiar with HDR photography, here’s a description in a nutshell.
HDR (High Dynamic Range) photography is accomplished by taking multiple exposures, generally 3 or more. The camera is set to take photos in different AV increments. Typically +- 2 stops will accomplish the job, but sometimes more are needed. Most newer SLR, and some higher end “point and shoot’s” will have a setting that will allow for a burst of 3 or more exposures +- 2 stops. The best way to tell in the field is to look at your histogram in each photo. You are looking for it to display from the darkest shadows, to the brightest highlights. Some compositions will require up to 7 photos, but you have to be careful, more does not necessarily mean a better photo. If you are in doubt, take 7 to 9 shots at 1 AV increments. You can always discard the images you will not need during post processing.
Because HDR photography uses multiple exposures, it is recommended that you use a tripod, otherwise ghosting and artifacts can appear. If you are shooting trees, it will require a windless day to get the best quality.
