I'm using the RED One on Wednesday in a hydroflex 435 zoom splash bag outside. I'm a little bit worried about keeping the camera cool. So far I've come up with having the grips give it shade, and putting cold packs in the bag (wrapped in diapers to take care of the condensation), and running the fan on HOT.

Does anyone have any ideas?

Are you in the jungle on the equator?

100 degree plus and 95%+ humidity?

Where are?

What's the shooting conditions?

Until we have facts, this seem like over kill.

Please give us some detail on shooting conditions.

If you put the camera in a small box/bag of any kind you may create a problem.

Under the sun, in a black and white hydroflex bag, locked off in the pond at universal in los angeles.

How hot can the camera get? And what happens, does it start giving errors or reboot like a computer?
 
If it is in the water that will help a lot. Water absorbs heat like crazy. If it was completely underwater then I would say you shouldn't have any problems. If it is not then a sun shade might be advisable. cold packs seem like they would cause more problems than anything. Running the fan should help.

Your best bet would be to run a test. Throw a thermometer in there with it and see how hot it gets. If it gets near the maximum operating temperature for the red then abort the test.

We had the REDONE in 95 degrees plus 95% humidity no problems at all.

We had the REDONE in a closed off room 90 degrees plus no problems at all.

You still need lot of dry air flows, so allow for largest volume of air inside the bag.

Just remember what ever air volume get recycled, and the camera put out heat. It will multiplied.

Get some kind of shade on top of the bag, with ceiling gap on top of one foot at least.

If you shoot with the RED RAID keep it out side the bag, it will be fine. Just tape up the ports and seal it good. If you leave it in the bag the heat problems will be worst.

P. S. RED did good in the snow too.

I personally would not use those for time lapse or set it and leave it applications.

Use the biggest bag, and try to keep it inflated with dry air.

There is a hole where the eye piece goes. Maybe you can patch a blower there. Running on really low setting of course.

Just be creative if you leave it on recording for long period.

Shots went off with out a hitch. Camera did plenty well, pictures of how the big boys do it should be up in the next few days. Ran it with the RED Raid and had it on AC power, just wish the DC power cable on the power supply was 10' longer.
 
Sorry for the late reply, got shipped to New Orleans on another job. Been in a hotel with a crappy internet connection.

Not sure, I don't think it's all that much though. I'll get pics up in the next few days.

So we had stuffed a red one, preston FIZ, angenieux 17-80 optimo, red raid, and onboard in this bag with no problems, and good results.

In the water again, but this time showing the wire/air loom coming down from above. :excl: I cannot recommend this, but I made the ac power supply water resistant, and powered the camera off of it. Wouldn't have made sense to pull the camera out of the water to change batteries. So I sealed all the connections with linerless rubber splicing tape and hung the loom/power supply from a c-stand.

Air tanks that power the blowers on the mattebox to clear the lens. Hydroflex gives you the option of using nitrogen tanks or scuba. You have to rent those else where.

If you have any questions PM me. One of the other assistants (Ernesto) that was helping that day may have more pictures to post.
 
Yeah, it's a SL Cine pan and tilt head from hydroflex, used for in water applications bolted directly to the platform. Basically a friction controlled head. Mostly for lock offs, but could be operated.
