[QUOTE="koboldstudios, post: 231682, member: 18551"] Glenn, I have the Rokinon 8mm, which is purports to have 180º capture (though I think that is only with a full-frame sensor). What I am trying to do, is set up a system where I am effectively photographing the sky, using multi-bracketed exposures. I want to capture everything from the horizon up. This then creates a "sky dome" image. I then take the multiple exposures and pull them into Photoshop, create an HDRI, then pull it in to something like Hugin to get my final EXR. I then take that EXR into my 3D software to light 3D animated scenes (or stills, like in architectural rendering). I have been thinking about ways to do this with the D90, which "chops" the image. I suppose I could take bracketed exposures at 45º increments, then stitch everything together, but that will result in a "messier" image. Ideally, I am very quickly grabbing my different exposures without manipulating the camera, or allowing for my environment to noticeably change. [/QUOTE]
