Tennie, I know you are enjoying your new camera. Isn't it fun?
I invite you to take the time to look at this: http://www.kenrockwell.com/nikon/d3000/ ... /index.htm
Much, much clearer than the user's manual. Ken Rockwell can be a bit dogmatic, I take some of his pronouncements with big grains of salt. But, for the big majority of areas, I agree with what he has to say. This is an overall summary, when you get down to the bottom you find "Details" with links taking you to six more sections.
When I had my D50 I laboriously copied this stuff into a Word-file, page by page, all the details ... highlighting and pasting from the web-pages to my PC. I took a disk to Kinko's and got thirty or so pages printed for a few dollars. When I wanted the D80 guide it was real easy ... one click downloaded a PDF-file I could take to Kinko's. Alas, doesn't seem to be a PDF option here.
Anyway, this really
helped me. I commend it to you as well.
