Polaroid 8x10 is used with either a large format 8x10 camera using an 8x10 polaroid back or a Daylab with an 8x10 adapter plus an 8x10 back. If you use the daylab, you can shoot 35mm and project on to the polaroid film which is held by the polaroid back. None of these options is inexpensive, by the way (unless you can rent a Daylab).
