    HDR allows you take a picture where all the dynamic range (the detail in the bright bits all the way to the dark bits) is represented. So if you have a shot with light streaming thru the windows you can see the detail in the glass and the detail in the shadows surrounding. Thats why you take a number of shots and blend then together.

    Photoshop creats a 32 bit image from the 8 bit images you import which means that instead of having 2^8 different shades you have 2^32 (a hell of lot more!) You can't view the entire dynamic range on a monitor or even paper properly (PS gives you an exposure slider). The trick is tone mapping the image to squeeze all the detail into an 8 bit image like a jpeg. Think of curves or levels correction as a way of tone mapping.
