Talcum Powder vs Epic

[James Drake]

Coming up on a situation with a lot of Talcum Powder being used on fabrics and things. The intention is to have quite a bit of it in the air, backlit.

Will the Epic be ok with the fine powder? Rain cover required?

Thanks for any input.

. . . never with my Epic - that's what hacked GH2's are for

Went to Burning Man last year - still cleaning the dust off everything that went with

 

[Phil Holland]

You should be fine. I just shot something similar and I've shot on Epic in far worse. I blew out the fan area with canned air when I could visibly see some build up. Remeber to be very careful when changing lenses in these situations. If you have access to nitrogen I would use it to blow out the sensor box.

 

[James Drake]

I respect that sentiment Josh.
Thanks Phil. We were on a Western shoot with some heavy dust... the camera was fine after some cleaning. My concern is that talcum powder is finer than the dust we were in.

Overthinking it, on purpose.

With all due respect to the guy above whom I totally admire . . . Always Suck - Never Blow

ie: Use a vacuum not canned air. Blasting air just drives the dust deeper into the cracks. Especially true with lenses - unless you want dust between the elements.

Canned air is for huffing to get high only. That's why they sell it in 3 packs.

Canned air also contains moisture...so it could get micro drops on your sensor if you spray to close.

 

[Phil Holland]

Lol. Yes. I agree. If its real nasty go with sucking. Nitrogen doesn't contain or carry moisture fyi. Cleaning optical sensors with it for around half my life.

 

[William Sorensen]

Agree with vacuum use... but whenever using a vacuum, make sure you don't allow whatever's being sucked toward it... especially lenses!

 

[James Drake]

Nitrogen and vacuum.

Check.

If it were me, I'd bag the camera. If nothing else, it saves a heap of clean-up time later.

+1, why chance any issues..

 

[Zeb B]

Always wondered how a camera that is producing 1000's of BTU's in heat likes having a bag over it.

 

[Jason Comparetto]

Just bag it. Put vent holes on the back or open it up between takes to let some of the heat out.

 

[Evin Grant]

Survived White Sands for 4 days just fine. That said we did bag the camera during one really windy morning (30mph+).

 

[Zeb B]

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.

 

[Paul Russell]

There really is only one solution:

:smiley:

 

[James Drake]

Bag.... like raincover bag? or cheap plastic bag?

 

[James Drake]

hahahaha. indeed.

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. :ihih:

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 :scared:

Eventually I stopped checking for dust on the sensor, and got rid my addiction (obsessive compulsive disorder)
