[QUOTE="koboldstudios, post: 231658, member: 18551"] Hello, I'm considering upgrading to a D610 next year from a D90. I am interested in compositing 7 or so RAW images into one HDRI for utilizing in the 3D work I do to light my scenes with "real world" lighting. The 3D HDRI illumination is an aside here, but it is my end-goal. To achieve the desired quality for my purposes, I am thinking that part of getting the best images for this requires I capture as much information with each bracketed exposure as possible. As I understand it, the D610 will have larger pixel blocks (I forget the correct term) on the sensor, and thus will provide greater dynamic ranger per pixel. Secondly, the larger sensor on the D610 will allow me to capture the full 180º required from my fisheye, whereas my D90 is truncating the image. For my purposes, I require 180º degrees of an image. Effectively I am capturing the "sky dome" for use in other software. Is the above logic regarding the sensor correct, and will the D610 a rational step in achieving my desired goal? Cheers, Mike p.s.
