  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

1st problems in the field...

Jim,
500 people died today in europes heatwave.must be bad.all over the news today.

Now that you've experienced the heat, get ready for the rain in Spain...
 
Well, with the climatechanges it will be alot hotter close to the equator.
Some areas will be so hot that no life can live there. I'm talking the surface of mars in some places.

As for the colors. Did you ever think of why it's black? Black reduces the chance of getting radiosity light reflexes from the camera body. If everything is black, the actors and set will be the only thing lit. A white body will produce alot of reflexes, a chrome one would be a disaster. Use a camerahouse instead (don't know their real names). A white soft house that you wrap around the camera.

this is (was) being discussed in another thread..
the "chrome" polish will get even hotter to the touch..
someone made a good point... go touch a black car that has been in direct sunlight... go touch a white car that has been in direct sunlight.. now go touch the chrome bumper... the bumper is the HOTTER of the two.

(talking out of my arse here plz forgive)

All things being equal, the Chrome bumper will always "feel" hotter because of the Chromium. Its a metal. Metal CONDUCTS heat better then paint, or most non metals (lets not talk carbon here). Imagine yourself in a sauna thats 250 degrees. The wood is fawk'n hot right? But imagine if they used metal fasteners in the construction (they don't). They would burn you bad.
People can "walk on fire" because usually they're walking on rocks, often glowing with heat(usually lava rocks) but with poor conductive properties. The ultimate example is the space shuttle exterior tiles. Even heated to several thousand degrees, and glowing, they can be handled without gloves!

ANY paint finish on your camera will insulate the body (IMHO) and tend to hold internal heat. That being said, body mods for ridiculous heat applications should be simple so long as the construction of the chassis incorporates it as a heat-sink. I can't imagine that it doesn't, it's SOP camera design at these wattages.

12V liquid cooling anyone?

Yeah but was that stills from the camera or stills of the camera on the set? I understand from the camera and development blah blah, just to see them rocking the camera on set.

Thanks for the update on the SS beta testing Jim. Much appreciated...

Sounds like you guys are on top of the situation. That exactly what beta testing should uncover - challenges and situations that stretch the limits of what the equipment can do. It's great to hear that the peltier system and revised sensor will be a thermal improvement on the beta prototypes. A light colored, heat absorbant "cool pack" that attaches to the camera via velcro or snaps, custom cut to fit the camera, affordable, and easlily removeable would work real well for those situations in hot climates where an umbrella wasn't practical (high wind, etc.). Maybe PortaBrace, Kata, or Petrol will make the cool pack I described, or better yet, maybe RED might think about making something like that after the camera development is finalized and sent for production. For most use, I think a black camera is fine. With a white cool pack available to cover the camera with, it would be the best of both worlds.

Thanks again for sharing the SS beta info with us...

Summer in Spain is very hot.

Have a look at the photo below:

Fata morgana view in Formentera today, Thursday, July 26, 2007.

Temperature 46 Celsius degree.

Speak American, dadgummit. Whats that in Fahrenheit? :innocent:

I know its 'sposed to be 105 degrees in Cordoba tomorrow. That ain't Honduras hot (where it feels as if it were actually PUSHING you into the pavement), but still...
 
46 celsius=114.8 fahrenheit

btw they are shooting in Toledo (close to madrid). And tomorrow temperature will be:
Maximum:
39°C (102.2 degrees Fahrenheit)
Minimum:
20°C (68 degrees Fahrenheit)

115 F ... s' pretty hot.

You guys should get past the size of the king's ass and maybe wander into the 21st century where the rest of the world is. ;).

So these exist? I thought about building something like this, but my concern was that something close to the camera would insulate, or at least hold a layer of air that would insulate - and thus keep heat in. And I also worried about dust. You'd have to have somewhere very clean, near to the camera to store the thing within easy reach, and throw it on between shots. If anybody can find a link for something like this, please post.
 
If the ambient humidity is low, evaporative cooling is very effective (eg. a fabric tent around the region of concern which is kept damp). http://en.wikipedia.org/wiki/Evaporative_cooler You would still not get surface condensation if the object (eg. a running camera) generates its own heat, since it would be warmer than the immediate surroundings.

However this approach does not work well if the humidity is high.

Jim, Do you have a moisture sensor that will detect moisture and turn off the
red camera?

I've tried to be careful, but jumping in and out of air conditioning in a car with the camera in the trunk - I've triggered the humidity warning a few times both in the tropics and skiing no matter how I tried to warm or cool the camera before hand. I'd hate to hurt my RED. Is this issue addressed?

Back a year ago on DVXuser when Jarred had the Red idea contest, I ranted on and on about heat, humidity, and my sweaty balls. Ignore the sweaty balls comments, but look back at some of my ideas.

Check out the link below. It was one of my ideas to use this chip in the RED camera.

If Jim thinks Spain is hot, he doesn't know what heat is. I have been to Borneo and the Amazon. It is so hot and humid in the Amazon, that your hair is always wet, even if you are motorboating down the river with the wind in your hair.

I live here in Miami. You guys in California are whimps.

Having shot 20+ days in Florida with your humidity, thunderstorms, hurricanes, alligators, and bugs, I can see why your condo's are all for sale right now.

There is a reason why Hollywood went to California and the reason is good weather to shoot. Now, if I need an affordable place to retire (and not be wimp (note correct spelling), Florida looks like the spot to be. ;-) (Note - my picture is from the Florida Keys with lots and lots of color correction.)

PS - Remember California has Death Valley that kicks Florida in hot temperatures and depth (below sea level) and some good cold weather too in something called mountains where frozen water (ie snow falls) something that is not available in Florida. ;-) except for Disney World's Matterhorn. PEACE.
 
jim maybe you could offer paint in that off-white cammo color that's on your jet and truck?
 
It is not reasonable to think that there will not be a limit to what the camera can do. Even with all our efforts, some simple facts remain:

1. You are shooting 4k in the package of uprezzed 720P. And recording to Compact Flash. Think about that for a second.
2. We have two high power FPGA's and a Rocket I/O that make this all happen. They are furnaces.
3. There are limits to all electronics. We are offering so much for so little, the temptation is to think it will fold your clothes for you after laundry.
4. There is no other camera that can shoot in 105 degree temperature without some precautions.

Please be aware that while this camera may be a miracle and a revolution (for $17,500) it is not without limits. Our job is to make those limits as broad as possible.

Jim
