Always wondered how a camera that is producing 1000's of BTU's in heat likes having a bag over it.
Just bag it. Put vent holes on the back or open it up between takes to let some of the heat out.
Would choking off the ventilation not drive up sensor temp thereby causing a Black Shading issue? RED techs have mentioned that changes in ambient temp requires a reShade. It's not the ambient that matters - it's the actual temp change on sensor. So . . . seems, at least in theory, if you bag your RED you need to run it up to full bagged temp, do a BS, then shoot at that calibration and stay at that temp for the entire shoot.
If you can bag your RED and do not suffer any BS issues then the "change in ambient" reShade guidance seems to be mythology.
Go big or go home, right on Paul :)
...still if you think about it, you can't just suck air out of the chamber. As much air will come in, as you suck out...in one way or another.
I was a sensor-cleaning-junkie back when I shot with my 5D. Yes, I was hooked! My mind always was contemplating if and how much dust got onto the sensor. I searched high and low for methods, cons and pros for cleaning sensors. Blowing air around was not recommended. Sensor swabs, was the only way to go. But it felt like a delicate surgical procedure evertime. It was nervewracking
Eventually I stopped checking for dust on the sensor, and got rid my addiction (obsessive compulsive disorder)
