High Detail Range Imaging = HDRI
You can use programs like HDR Max or photomatix or easyhdr (very simple to use as name says).
A. you can either take 3 photos
B. Photoshop 1 photo to make 3
You need to change the levels(forgot real word, but in photoshop this will do it) on the pics so that one is brighter and one is darker and you haev original. then in your hdr program put in your 3 pics it'll merge the 3 and voila a HDR image, plus a little bit of tweaking to your likings in the sidebar
.
Basically it takes the good bits from light and dark pics and puts it in base pic..
