you can take long exposure photo's with any standard or automatic single lens reflex [SLR] camera, with aid of a tripod.
you can pick these up relativly cheaply from second hand stores or camera outlets, depends on the make and model you want.
standard disposable or point and shoot cameras will not give you the reults you are looking for, dismembering the flash wil not help either, adding a flash to a long exposure can add definition to the photos too, all depending what you want the photo to look like.

In giving love there is an equal grace.
Nor need one seek the aura in the face,
As love unveils the beauty of all things."
