Playing With HDR Photography


There's a fairly new technique emerging in the world of digital photography. Its known as HDR Photography. This stands for High Dynamic Range. Put simply HDR photography is a method of taking a series of shots, each at a different aperture setting, covering a large range of lighting values. Then, using special HDR software to combine the 3 to 8 shots of the scene to create a single photo which would be impossible for a digital camera to take in a single snap. It leaves you with a picture with no under exposed areas, no over exposed areas... perfect sharpness and lighting balance and a color depth rivaling the best single-photo shot's made.

Now that I've basically explained what HDR is, I did a basic demonstration using a software package called Photomatix. This is software specially designed to create HDR photo's. What you will find on the link below is a series of photo's. The first six small ones are each shot taken at aperture settings starting at -2 all the way up to +2. This creates extreme shadows to extreme brights. Then the final (7th) large image is the final HDR product. You'll see there is perfect lighting balance through the entire photo. Not something I could have done even if I spent time setting up a single shot to be perfectly lighted. The final photo has the software's watermark on it because it's still in trial mode. I have not yet purchased it. But so far I'm very impressed!
