Fun with Photomatix and HDRI
Hopefully next weekend I’ll be going on a photo shoot with a friend somewhere out in Chicago. For at least some of the shots, I was hoping to do a little playing around with high dynamic range imaging (HDRI). It’s a photography technique that increases the range between the lightest and darkest parts of an image by merging multiple exposures of the same shot.
Yesterday I was reading up on some tutorials and found you can cheat it by processing 1 image into the various under and over exposed steps and merge them together. So I dug up the RAW images of my trip to Rome a couple of years ago and had a bit of a play. It might not be true HDRI, but they certainly look interesting.
Update:
About the sources used to “cheat” HDRI. Its actually rather easy if you are using photomatix: copy the picture the amount of times you want (need about 3-5 total), drag them into the box for “generate HDR,” and the program will tell you they are the same exposure and ask if and how much you want to change the E.V. spacing. There are a few other ways to do it, but that’s what I did.
My entire process was pretty much taken in bits and pieces from these 3 tutorials:
