A Polaroid that prints straight out of the camera, right? You can pick those up anywhere really. The Polaroid I had was a digital compact. I advise picking up a cheapish 2nd hand fully manual 35mm or 120 (medium format) film camera on eBay, you can likely find entire kits including kit bags that people are getting rid of as they have recently purchased a DSLR. Look for Pentax, Olympus then Nikon in my opinion. It's all a matter of personal preference, but a notable thing about Olympus manual film cameras is they are quite small in your hands. Depends on your hand size I guess. The reasoning behind getting a film camera first is that you will learn how to judge light, and overcome the partially blind automatic modes on DSLRs. When you take pictures, note down the shutter speed, aperture and exposure level, and possibly the zoom level or sky condition in a small pocketbook. Once developed, you will know what was right and what was wrong.
Goodnight man.
P.S. Use Ilford HP5 400ISO or XP2 400ISO for Enniskillen light.
