What is the difference beetwen Nikon D3000 and Nikon D3100?

I'm looking for a specific answer like, the actual difference when you take pictures.

100.
Ba boom shht.

Huge if you are interested in shooting video too.
The D3100 has Full HD video and can auto-focus in the video mode as well. It has a lot of features for the small $150 more, well worth it for most people
Compare the two yourself

The pictures are of a better quality. Both because of the higher shooting resolution and the fact the D3100 is a newer camera. The D3100 also has HD video recording, a feature not present in the D3000. Also, the D3100 is much better for "new" photographers (i.e.those that have just moved from a compact to an SLR) as it has a guide mode. If you're going to buy one, I'd suggest the D3100.

D3100 has a bigger LCD screen, Full HD And HD Video, Live View, higher ISO range with less noise.
It's a much better DSLR.
