A lot of my pictures are taken through my sitting room window so cold isn't an issue with them. LOL
As I'm now getting on a bit, I'm reluctant to go out when the roads and footpaths are icy. But in the past, when I was braver, I never gave the temperature much thought, except I noticed that the batteries didn't hold the charge for very long.
We don't get the extremes of temperatures here that other countries experience 18-24C is a normal summer temperature. Winter is remarkable if we get anything lower than -2-3C and don't usually get that low for more than a couple of days. Mostly winters hover around freezing to 5C during January & February.
