Thats an odd question. Its like asking who build a house with a MasterCraft hammer. Does it matter what kind of tool was used? As long as you have shutter control you can take the series of shots needed to make an HDR image.
D-B-J with the D7000 you can program the 2 User modes so with U1, A, U2 you can shoot 9 shots for HDR. I did a post somewhere here with full instructions.

As has been said by others, the T3 can certainly do HDR work, in fact its possible with any DSLR on the market (heck even many point and shoots can do it).
Without any proper topic to be the focus of the thread I'm going to lock it for now; if JRE313 wants to re-open the thread just send me a pm with some kind of additional structure/commenting/question/topic to be edited into the first post and I'll put it in and reopen the thread.
