Just a question in passing, but I assume from BB's posts that the HDR image is smaller than the LDR in his example (or why isn't it as sharp?). An HDR image that's 8000 x 4000 should be sharp as a LDR image at 8000x4000, shouldn't it? I mean, it's the same image, just with greater luminance data in 32bit... isn't it?

Reason I'm asking is that I just realised that Carrara has a spherical camera and I can fake HDR in photoshop by stacking images and converting the stack from 8bit to 32bit. I'll probably still play with that, but it'd be nice to learn more of the niceties of HDR along the way. The idea of being able to set up a wide background scene in Carrara (including sun position, colour etc) and project it as a pseudo HDR image in Poser has some scope for play.
