Lightroom CC has a new multi Photo auto HDR functionality. Just click three exposure bracketed photos and press Ctrl-H, wait a few moments for the preview then click merge. Not as rich as HDR Pro, but detail in the shadows is pretty well preserved and the images automatically added to a stack. All my images are taken handheld for really long telephoto with a monopod. The software is not as robust as HDR Pro, but more than nine out of ten times, the bracketed images can be merged with lightroom then further processed with Topaz.
