Still cheaper than printer ink.

p.3 #3 · Not a Good Day For Nikon

Well my D200, D70s, and lowly FM10 just survived a couple hours in the blowing snow here in Omaha. I took them all downtown and they hung around my neck while I walked around town. All three were covered with snow on top and functioned from start to finish. Of course, it's "only" in the 20s here today.. so...

ya got that right for the Epson 2200 it works out to

10ml / 13.00USD
do the math , i might mess it up , my math has it at near 5 Thousand dollars a gallon, but i could be off by a factor of ten i am severly math challenged

$13/10ml * 1000ml/L * 3.785 L/USgallon ~ 4920
That's impressive profit margins! Boy oh boy Exxon et al have nothing on these guys!

Anyway, my D1H just survived being out in the blowing snow the other day... It was only -3C though (ambient temperature)... And my D70s survived a good 1/2 hour at around -20C temps... So there's my "tough Nikon body" story

I'm waiting for Exxon branded printer ink. I feel kinda bad their CEO didn't make much of a bonus last year.

My worse case Nikon experience was getting stuck in a sudden downpour where the camera was dripping wet. After half hour got back to the car and wiped down the gear as much as possible. Everything worked as expected throughout the ordeal.

I guess he must have been out of favour with the good Lord that day. Fancy this not occuring to him!

I was just wondering which of the Braycote products was approved for spaceflight. Bracote 806 perhaps, just wondering which I should buy to send off to Nikon with my camera. At $90.00 per 2 ounce syringe you want to make sure you know?

You know here's something to think about the cameras NASA uses. The vacuum of space is a really excellent insulator and objects in that vacuum radiate heat slower than we are used to. I wonder how cold those cameras ever really got. Just a thought.

There are plenty of electronics that will work at -45 degrees. The telecommunications industry has all sorts of electronic gear that works in extremely cold weather without any heat being supplied to it.

I did plenty of film shooting at temperatures from -20 to -45 degrees and never had film break on me. I had to advance the film very slowly or static charge would cause streaking on the film, but as long as I put warm batteries in and shot right away, I had no other problems.

being able to shoot right away isn't always an option.

In space it would indeed take a very long time for an object to loose its heat. From what I've been able to gather about this, within about the same area as the Earth's orbit, in the shade the temperature would eventually reach about -160 C (-256 F). If placed in direct line of our sun's rays, it would reach about 200 C (392 F).

On a more "realistic" level, the temperature that spacesuits deals with range from -73C (~ -100 F) to about 115C (~235 F)

Take it for what it's worth.

I would be curious to know how the LCD handles the cold. The other components are probably fine. If we can handle the cold, the camera can. But the LCD does have some limitations. I have seen laptop screens crack from being to cold.

Most electronics actually perform better at lower temperatures. The processing speed of a desktop computers CPU can be increased 2-3 fold if cooled with liquid nitrogen - a fun geek thing to do similar to running an engine until it blows up.

Imagining sensors for extreme low light/night time photography are often cooled to very low temperatures to increase circuit efficiency and reduce residual noise caused from heat.

So keep the camera next to your body under your jacket until ready to shoot, or stay at home and keep warm.

Keeping it under your jacket and pulling it out suddenly increases the chance for issues with condensation.

The remote battery solution is the best way to go.

You mean like the ones built into telescope imaging sensor blocks like this one. Or this one.

Nitrogen cooling only helps you overclock higher due to lack of upper temperature limits. Two processors with the same specs and clock speeds aren't going to perform different even if one is cooled to subzero, and the other left at nominal operating temps. When it comes to chips, I would say they perform horribly and inconsistently above design temperature, but between nominal and really low temps, there isn't a performance difference. Cold changes the properties of charge holding components such as batteries and some capacitors.

Cooling lowers resistance and production of heat - the two most basic negatives with electronics. You're correct that two processors with same specs and clock speeds will not show performance difference if one is supercooled, but it will increase lifespan due to slowing down of thermal breakdown. And super cooling allows a circuit to be run at much higher than performance levels.

Now taking this back on topic, using electronic equipment in extreme cold is not a problem (as opposed to extreme heat) as long as moisture/condensation and proper power supply issues are addressed.

Unless you are perspiring, that chance is pretty remote. And, when it is -30 to -40 degrees, you usually have so many other clothes between your body and your jacket that little, if any,
condensation from your body reaches the camera.
