You're right a truly HDR shot could not be made from one single shot. If for example you use a single raw file and adjust the exposure, and save each variation to make up a complete set the trouble is that the single exposure has a fixed dynamic range, and changing the exposure value in post-processing doesn't create a noise-free shadows or recover the lost highlights. The shot is bound by the limits of the camera's snesor and the only way to overcome this is by shooting multiple images.

A useful tip that answers something I was not sure of. Thanks. |

It's true that you can't create a "real" HDRI from a single exposure in cases where the dynamic range exceeds that which a sensor is able to capture in a single exposure, BUT... The sensor is capable of recording a broader range than we can display "naturally" on our computer screens. If we take these single-exposure, contrasty shots and tweak them so that both extremes are rendered, they look very flat. If we use Photomatix tone mapping or Topaz or other such approaches on the single exposure, we can increase local area contrast while still containing the limits, and this can be very desirable. Example:
From this: 
To this: 
That's Photomatix tone mapping on a single RAW exposure... Not super-exaggerated, very faithful to what I was "seeing" with my High Dynamic Range Personal Sensor (aka as "the human eye").

My first entry using PhotoMatix
Original
My best result using PhotoMatix
I must say, I learned a lot about HDR reading and asking  Bear_Music about the topic.

You should be able to also do it with a 16-bit TIFF file. I can, anyway. IN other words, I can save any JPG as a TIFF in PS, then do image/mode/16-bit and save, and then I can "tone map" it in Photomatix, though the results are much more limited than working from RAW.

Cool I didn't know that, thank you..

| So I guess the consensus is PhotoMatrix. |

Very much so, and it's Photomatix, no "r".

| I downloaded it off their site. Will this program allow me to merge three images of different exposure. It doesn't look like it does, at least the free version. It just allows tone mapping to one image. |

Yes, the free version is what I am using and it does do that. Open the images in Photomatix and select HDR--->generate from the menu. It will ask you if you want to use the opened images. It will then spend some time merging them, after which you do tone mapping to get it to look how you want it.
The free version will not give the over the top look that everyone associates with HDR, but I have found some additional adjustments in PaintShop Pro will get it there for me, if that is the look I am after.
This was 3 exposures, merged in Photmatix basic, with some clarify thrown into it afterwards using PaintShop Pro
