This is a complete guide for getting started with the Polaroid Land Camera. It goes over cheaply acquiring the camera and film, upgrading the battery, basic functionality, timing exposures, photo tips, and using a flash.
It may take a little while to get the hang of it, but you will quickly learn it is a ton of fun. There is a sense of anticipation as the photo develops that you just don't get from digital photography.
Step 1: Find a Camera
You can still find them at thrift stores, garage sales, estate sales, antique stores, and online (think Ebay).
Your best bet is to find one at a garage or estate sale. Although antique cameras sometimes tend to fetch a little bit of money, most people think you can't buy Polaroid film anymore and will offload these cameras on the cheap.
The current market for Land Cameras is good because no one wants to buy them and everyone wants to be rid of them. This makes your job of acquiring one all the easier.
I got this whole camera kit for $5, and with the warning, "You know, you can't get film for those anymore."
