Pete, I got a few more pictures in my user gallery for you. They are more or less just overview pictures of the lighting projects that I am working on, but you are welcome to have a look. They are not super close ups or trying to get the light exactly right - yet. Mr X
As others have said a tripod is a must. Just experment and document as you go with exposure and F stop settings. I used some back lighting in the room for some of my shots as well as a flash light. Have a look at some of the flicks in my gallery. I also have a macro lens.
As I've said before, it's a matter of experimenting. As L Lee Davis said, document what you are doing so you don't repeat your mistakes, and find out what works. I did that for two years before I found a combination that worked for daylight shots. Night shots are even harder. With a digital, you are only wasting electrons, which were pretty cheap the last time I checked. I'll also set up a shot, on a tripod, take a few exposures, and then bring the card (not the camera) into my office, where I can look at the images on my computer. I can see on the computer the adjustments I have to make much better and faster than looking at the backplate image of the camera.
