Gremlin- I am basically in the same boat. I was overwhelmed when reading through the manual. I immediately plugged the battery pack in, and once it was charged, I took about 10 pictures in basic modes, just to get the feel of it. I then promised myself to use nothing but the creative modes. I then wrote down the creative modes, and tried to pick each one apart- taking notes. For me, it helps when I actually write it down. I even went as far as instead of writing "Tv", I would write "time value" for example.
I want to learn the right way...even though it's a slow road, big learning curve. I have looked at things on here, like moon photos, and found the information on what settings were used and such, just to get a good ballpark setting. But I want to understand why the ISO should be set at 100, or why the shutter speed could be 1/250. I would have thought that due to the fact that it's dark out, the camera needs a lot of light, so a 10 second shutter speed has to help. Thats why I am here. Theres a wealth of info here, and more than I could ever possibly consume.
I shoot amlost everything in Av or Tv, and once I get somewhat comfortable with that, I will dig a little deeper. I learn something every day, even if it's something small. So many buttons, options, etc., I just learned yesterday how to select the AF point with the dial. The button has been there by my thumb for over 300 pictures, and I just learned about it.
I know I am ramblin', but I thought it might be helpful. Starting from ground zero, and building up from that has to make a solid foundation. Just get out there and take some pictures...just having the camera in your hands is like "seat time" in a race car.
