Digital cameras and the cold

The other day I brought my pentax optio 330 into the house from
outside in the car. It was about 40 degerees F. Taking a couple indoor
pictures with the cold camera without the flash resulted in orange
tinted photos, Using the flash the pictures looked right. Is there
something about ccd imaging devices that would make them react this
way to cold? Just curious.
Thanks,
Eric R Snow

Maybe you should blame it on the background lighting without the flash. What
was providing it and how much light was there? 40F is not cold.

I think the previous correspondent is on the right track.
Your indoor lighting will have a colour temperature quite different to
that of the "normal" camera setting which is undoubtedly for daylight.
The flash colour temperature will be very close to natural daylight.
If you want to take photographs indoors without flash you can, or
should be able to, change the camera's setting to take into account
different light sources.

I just checked the specs on my camera- operating range minimum is 32F

Getting all those nice yellows from the incandescent lamps.

If you were living in Minnesota- why would you complain about +40F? come
from further North and west than Minnesota- Alberta- and now am in "balmy"
Vancover Island where it is now about +40F.

I've lived in California for several years. I'm only human, we get spoiled. ;-)

Thanks!

You must live in Minnesnowta:

For a being whose normal body temperature is 98.6F, 40F is COLD!

And yes, cold does affect electronics - I wouldn't be a bit surprised if a
cold CCD has color skew.

Cheers!

Maybe even the humidity change form the cold outside to a heated home. That
can and will cause occasional problems with condensation. However I agree
with the probability of the lighting, or lack thereof, to have caused the
colour skew.
