Single-shot HDR images in Photoshop

I can create a single shot or faux HDR Efex in Photoshop rather in the way you…would think I would, by simply taking a RAW file, processing it in three…different ways, and then merging the results.…If you were to sit down and just try and think your way through this problem, …you'd probably have no trouble figuring it out, but let's walk through it anyway.…Let's say that I had only shot one image of this car instead of the full…bracketed set and I had shot it as metered.…So I am going to open that image up in Photoshop and of course, it's a RAW file,…so I get my RAW dialog box.…

Now normally when I am passing the RAW files off to another HDR program, I don't…worry about any RAW conversion parameters.…In fact, I am not even given the chance to adjust RAW conversion parameters.…I want to simply hand the full data set from each file off to the RAW converter.…Here though I do need to think about things that I might want to do in the RAW converter.…If I had overexposed highlights, I would want to recover them.…
