Through playing with HDR shop I can achieve "OKAY" results just using variations of my images.

Using several images and adjusting the brightness, then saving the output file as HDR. It actually still contains light data needed for that scene. It's not perfect but it certainly is a quick fix if you need a quick HDR for a scene.

Open HDRSHOP.
Choose Create/Assemble HDR from Image sequence.
Calculate and Finally Create..
Save output as HDR and you're good to go.

Yes, of course. I've found that it works well with almost any image with interesting lighting.

The results are obvioulsy not as good as the right way. But they pass.

dunno, to me the reflection is still very flat in appearance.

I think with a few tweaks here and there, it could work.

One difference between using an image or a HDR in the Lum channel. The HDR although not accurate still has some light information. I can see the effect passing through to the floor with my HDR images, but obviously with a regular image I get a single color.

I've tried spectrum-HDR's.. They also work quite well.

I messed around with this approach a while back, and it does have a few drawbacks. Particularly if you have multiple objects in your scene with varying levels of reflectivity. With a real HDRI, you'll be able to see details in some reflections that are not visible in others. With a "fake" HDRI, the image has the same details at every lighting "stop," because everything is a variation of one exposure (unless you paint in detail that isn't already there), so you miss this subtle but important visual cue in the final rendering.
