Hi Pinhole,
When you want to increase the perceived dynamic range of a photograoh, and maintain the look of a normal photograph, you generally have to do a bit more than just apply a filter or straight forward settings. You'll end up working in layers a lot, with different layers for fore- and background, and/or for the areas in the low and high parts of the dynamic range, and essentially treat those differently and balance them. In a way like you would do in the darkroom in the past, overexposing some parts, underexposing others, and developing some parts of the image differently from others. Tools from companies like Nik Software and Topaz Labs make this process a lot easier, as they pack some tools where you can do the individual bits with a couple of sliders rather than having to go through hoops and loops, and a considerable larger amount of time.

Is there another name for that than HDR? What HDR in its original definition can do is hold a very large dynamic range, and then you can compress it into a smaller, outputtable range, but then losing some of the gradations in the middle. But adjusting different parts of the image differently can give a much nicer effect, much more subtle and with better tones. Is there a good name for that, or is it all just mangled together under HDR?
I haven't played around with HDR and the like as much as I'd hoped; apart from doing it by hand in PS, are there any programs where you (perhaps with some help) select areas to tone separately rather than just adjusting one extra-long tone curve?
