Also, if you are talking about "fundamentals in HDR",
-You need [normally] three shots of the same exact thing, but with different exposures. You can set this up easily using the Bracket shooting and shoot 3 consecutive shots. 1 'Overexposed', 1 'normal', 1 'underexposed'.
-Load up the shots in the HDR software, let it churn out, calculate, etc. And tweak the settings [if given any, like in Photoshop],
-Voila! HDR goodness!
I recommend you get a tripod for HDR images, because if you don't, the final image will look screwed. Any single movement in the frame will be reflected as 'faded images'. So, I'ld recommend avoiding doing HDRs on moving objects like people, awake animals, trees on a windy day, you get the idea.
Try HDR by starting with things like your room, or house, or a simple object. experiment!
Have fun!
