Does anyone know how to automate the process of loading a single RAW file in Photoshop and saving it in the TIFF format at various exposures? More specifically, I'd like to point Photoshop to a RAW picture and have it save the image as three .tiff files, one at the original exposure, one a stop above, and one a stop below (or any other configuration I want to experiment with). I thought that I could set this up in seconds, but it's proving to be a bit more difficult than I anticipated, mainly because I've found no way to bring up the RAW dialog after closing it (without opening the picture file again).
If it's not already obvious, I'm asking about this because I want to minimize the hassle and time it takes to create an HDR image from a single file -- opening and closing the file three times is making me crazy. Speaking of which, a few days ago I asked if there was anything better than Photomatix Pro for creating HDR images. I received quite a few responses from that query and had my suspicions confirmed: Photomatix Pro is currently the best thing going.
