I am fully aware of what hdr means. When I made reference to increasing the dpi that is because if you look at any reasonable photograph say one through a Nikon D610 or the humble smartphone the pixel ratio is way over anything Daz studio puts out. Professional HDR programs would prefer to be working in Raw (Raw file size is typically 2–6 times larger than JPEG file size). This is not just Daz studio issue but many apps of this category. I do not have to use my scroll zoom far to see an image start to fall apart. When I tried to use renders I found the digital artifacts undesirable. HDR/I refers to High Dynamic Range and it is basically tone mapping PIXELS and altering their state. Because we are talking about computer based conversion and not thru the lens you are starting with low dynamic image and layering 3 together each changing the luminance via the differing algorithms and in turn gives the depth and color you seek. It does have quite a bearing on the pixels if you would like something worthwhile at the end result.

Your comment about the Iray render engine using HDR or lack of option to output HDR might be on purpose. Iray is now appearing in other platforms. When a licensing agreement is struck up between two companies they may not always get the fully functioning software that would be very rare these days. You get a stripped back version which does the job intended but nothing more. Iray turned up recent update Substance Designer now gives you the ability to preview in Iray nothing more. This is all that was required and I could see it being very handy for a Daz content developer to preview the materials they are working on in the same engine the material is to target. Indigo are doing similar Render engine in affiliate software but go to their store and buy the standalone version if you want fully featured. All would be fools to give us their full spec render engine inside another program they would be shooting themselves in the foot. Iray more than likely will have no issue rendering in HDR just not from Daz that I can see.
