I want to take time exposure strobephotos in Physics classes at school. Is there a Polaroid camera which still offers the possibility to leave the shutter open as long as I hold the button down. The old camera had this but I can't see it on the new models. I would like to have instant photos of motions taken with a stroboscope.

Thanks
