We work in a field where, whatever we buy something for, we use for its intended purpose. Sometimes we just want to save money and dig through our stuff to see what else we can use it for. Here's a list of things you can use your gear for, either in a pinch or as a better replacement for something else.
Tripods are probably the most widely used piece of equipment variety wise. If you're handy you can track down a vintage tripod at an estate sale or eBay and make it a lamp. This is probably my favorite use because it really puts photography on display in your living room and gives a unique look to your living space. If you're lazy like me, you can buy an awesome one pre-made.
You can use a tripod as a gun mount. Yup, pretty amazing. There is a company called Hog Saddle that makes mounts that specifically work with Manfroto tripods. It was designed by a Marine Scout Sniper as a rifle rest tailored to the special operations and law enforcement community.
If you're in a big pinch and heading out from a shoot, always keep a cheap umbrella around to combat rainy weather. At $13 they're not bad when you need to cover your expensive gear. Just try not to use the $11k Broncolor umbrella.
C Stands mostly are used for hanging laundry. Either wet laundry that you want to hang dry, or when you're too lazy to put it in the hamper and you just throw it on your C stand.
Lens cloth's are awesome because they're some of the softest cloths for your camera, but they work wonders on your eye glasses as well as your computer screen.
Dust blasters work wonders on keyboards. You know when you're sitting there and you notice something stuck in your keyboard? Instead of jabbing at it with a pen, yes I know you have don't deny it, use your dust blaster. Makes your life a lot easier.
Video Lights are a pretty obvious use for alternative light source. Most people use them as painting lights. As you can see we put them to good use painting the Fstoppers offices.
Super clamps can be used for mounting pretty much anything that isn't photography related, but easiest and most feasible is surround sound speakers. If you have curtains hanging, you can mount them to the rod.
We'd love to hear other things you've used in alternative ways, so post them in the comments!
