I'm aware Hugin has HDR capabilities and at least it treats EQR's intelligently. What I'm not is clear about is how to really use these features of Hugin. I also really like doing adjustments in Lightroom as much as I can. Thanks for the pointers to the Hugin instructions. I'll find some time to go through those and see if I can figure it out.
Also thanks for the cube face translation links. I searched for tools to do that recently but only found some old apparently unsupported stuff that didn't seem that straightforward to use.
I just wish LR and PS would add a feature to treat EQR's properly. (and also add reversible rotation tools for zenith/nadir editing.) Seems it should be easy to add that.
