[Closed] HDR Photography

Yep, yet another photography thread from me.

So Ive been looking around on the net at HDR photography under the impression that I need a super amazing fantabulous camera worth more than I will earn in a lifetime to do it. Was quite suprised to discover that I can dabble in HDR using just my little Nikon D70.

I found a basic guide to HDR and followed the instructions. Camera in Manual mode, ISO set to 200, tripod ready. I arsed around with the menu settings a bit and changed various things and took some photos in the house, sure enough the camera took 3 snaps (one normal, one really dark and one really light)...nice one, seems to be working.

I go outside and setup to take some photos of the cliffs, storm clouds and light breaking through the clouds. Camera is already set and it takes 3 photos...but they all come out absolutely bright white with only a small amount of detail recognisable. Im assuming it was an aperture issue but I didnt have chance to correct it as it started raining.

Is it worth pissing around with anymore to get it right or should I just sack it off as a waste of time? Do you need special subjects/content to take advantage of HDR stuff?
