These were both shot with a Canon 10-22 EFS on a 20D. 5 shots were used for each photo, combined into an HDR with Photomatix, tonemapped to 16bit with Photomatix (with all the tonemapping settings turned down to 0 -- I hate Photomatix's tonemapping!), then toned with Photoshop CS2 and downsampled to 8bit JPEGs. I've found that the key to HDR portraits is to have a model that can hold very still, a study tripod, and a cable release.
