HDR - Served up RAW

Last night for my Intermediate Photography class that I am taking at Vancouver Photo Workshops we had a field trip out to the Vancouver Art Gallery were we attempted to capture some shots to later process into HDR photos. It was mostly a cloud free evening so the skies weren't as dramatic as they could have been but we did our best. Tried several different shots and also did some long exposure night shots as well. All of the shots taken were shot in RAW and processing them afterwards was very time consuming and took a lot longer than when I had tried doing HDR with jpegs. I guess this was the result of huge file sizes and amount of information in each RAW file.
