HDR stands for High Dynamic Range photography. The above image of The Cathedral of Our Lady of Lourdes in Spokane is a combination of 5 different exposures. I had one middle-exposed photo and then an exposure was taken 2 stops up and 2 stops down. There are ways to combine them manually using Photoshop or GIMP, but to get the above effect I used a free software called HDRtist. It takes the different exposures and combines using it's own tone-mapping algorithms. The result is this sort of surreal, painting-like effect. I wish I had more control of some of the parameters, but hey, it does it for free.
This image is just a block from our home. These are some condos and townhouses in the new Kendall Yards development. They are building at lightning speed!
