I've updated my Photomatix tutorial to include more stuff. Photoshop vs Photomatix. Why use 3 RAW's, why use 1 RAW. There's info on Photomatix's new feature where you can load a RAW file directly into the program and generate a HDR from that. Why are TIFF's better than JPG's. A comparison between making a HDR using 1 RAW file and producing 3 TIFFs from that and shooting 3 RAW files on site. Information on Photomatix's latest features showing how you can produce arty shots or how you can produce nice natural looking shots, your choice.
