Question about HDR photospheres

So I'm trying to take HDR photospheres to use as environment maps in Daz, and I've been having issues with the sphere's ground area not lining up with the ground plane of the scene. My question is, how far off the ground should the photosphere be captured, so that the environment map's ground area matches the ground plane of the scene?

    Alright guys, I've figured it out! I did some testing of photospheres, and it turns out, that to have the best results for use in Daz as an environment map, you want the camera to be on the ground when taking the photosphere, with a field of view of around 94 degrees. The reason for the positioning is that environment map photosphere that you use as actual environments for your characters to stand in, uses the bottom of the photoshere as the "ground" plane. I originally thought that you needed to take the photosphere at waist height, to match the sphere with the frame of the render, but that is NOT correct. 

    Just a helpful discovery for anyone interested in creating photosphere HDRIs to use as environments in Daz. 

    By the way, if you're interested in using Nvidia Ansel to take photosphere HDRIs in games to use in Daz, the settings I listed above will net you perfect results, with minimal tweaking needed in Daz to make it look correct.

    What do you use to assemble your photospheres?

    I haven't done any physical photospheres in a long while, but I've done a bunch of digital ones using the Nvidia Ansel feature in videogames. That's what I was referring to with my research.
