OK. Who doesn't like shooting fire and sparks and molten steel in vats as big as your house? The only problem is that high-end camera lenses are held together with glue—specially developed optically pure glue. After a long exposure to temperatures exceeding 100 degrees Fahrenheit, this glue tends to loosen. Then, instead of a camera, you've got a $10,000 paperweight on your hands. I looked around and couldn't find any jackets designed to keep a camera protected from heat. Everything's designed to keep them warm from the cold. So I went out and bought some reflective material at a sewing shop and created a pattern template out of grocery bags. My wife can sew, and in two days, she created a brilliant heat jacket for the camera. It worked better than my expectations. I wish I had taken a picture of it on the shoot.
