I did a simple interview-style shoot at an indoor location on Saturday. It was very hot outside but our set was dark, air-conditioned, and cool (See picture below). An overheating Canon t1i was the farthest thing from my mind. We didn’t even use lamps—we relied on a single ray of natural light—using a windshield reflector to bounce it into the subject’s face. But an hour and ten minutes into the shoot, I saw the red, blinking thermometer on the right side of my LCD screen. I kept shooting for a couple more minutes, knowing the script was nearing the end. Those were a worrisome few minutes but luckily we completed it. Thank goodness we weren’t shooting outdoors (the original plan!)

An hour of shooting in a cool location? That’s not very impressive. So here’s what I want to know. Is this a common problem with DSLRs? How do you deal with DSLR overheating? Do you turn it off after every scene? Do you have a special contraption or fan that you use to counter the heat? Do you have a backup camera?

In case you're wondering, that's a cheap Olympus digital audio recorder I'm using. I can't afford the Zoom h4n just yet.
