Crispy morning

I stopped on my way to work this morning to take some shots of the low sun on the frosty ground. I took my big camera with me to put it through its paces, and thought I’d got some lovely shots. Got home tonight, put the SD card into the laptop to copy the shots over, and found that none of the ones I’d taken this morning were there! None of them. Was it too cold to save them? How annoying!
