I think you meant to ask a different question, a Digital Single Lens Reflex camera is just the "new digital" form of camera, compared to the old film type of SLR camera. I think you might have wanted to ask what are the advantages of a DSLR compared to a point and shoot type of camera. Way too many things to cover in a short post, but basically a DSLR will accept interchangeable quality lens that serve many different purposes, it is a camera more suited to more advanced photographers. There are many advantages to such a camera, but it can become extremely expensive also. The point and shoots , are much more for the new amature photograher, cheaper and much lighter without all the weight, bulk, and expense of a DSLR with all the accessories. I use a point and shoot and for my plant photos, and other "amature" photo shooting it is all I need.
