Operaguy The output (often called probes) from HDRshop and other such progs. are not really for use as stills. They attempt to contain the extra intensity information that real world lighting has. This can not be re-produced on a monitor or photo. Once you have got hold of your probes (stop sniggering at the back) It still takes a 3D program to interpret them. At its simplest a program could just interpret the 20 brightest points of the probe and create a light set mapped on a sphere. With more sophistication you can use the information in the probe to control the percentage intensity of individual lights in your light set. So having set up your HDRI environment you animate in the normal way. Apologies if this was too simplistic, someone may find it useful!
