DIY: How to Make an LED Macro Ring Light for $10
Macro photography is fascinating, but it's not easy, and it takes a bit of special equipment. One such piece is the ring light. Ring lights sit at the end of your lens and replace your normal flash with one that's right up close to the subject.
If you want to avoid shelling out the cash for one though, you can always make your own. There are plenty of tutorials online, but the one that produces the best looking result for the lowest price is over at Instructables.
User Ruta9 created his ring light using a 48 LED camping light that sells for around $7, a busted UV filter for the threading, and a broken cell phone charger. The DIY ring light even sports a diffuser and a battery case for your camera's hotshoe.
