I cant comment too much on your worflow because I havent experimented much. however, I have had some great results by working as follows:
- generating HDR images first for the bracketed sets. ( I've been using Photomatix to batch combine all images if there is no movement or manually with Dynamic Photo HDR if there is some movement) -Using these images in hugin, generating control points etc and outputting only an EXR file -tonemapping in either photmatix or dynamic photo hdr. Its worked great for me so long as the images are lined up well although I have found parallax and alignment errors really show up with HDR. With regard to your workflow - How are you generating your 16bit TIFs? and how come your working that way, ie not importing HDR images into hugin just out of interest?
