I took a photo with a SLR on a snowy day, and when I got home, the camera frosted and water droplets appeared. What should I do?

This situation is very obvious, especially in winter, so we must be more careful.

Put a thermos cup in the camera bag when you go out in winter to keep the temperature rate in the bag high. When the camera is not taking pictures, try to put it in the bag, and put some moisture-proof agent in the bag at the same time.

In other words, let your camera and lens warm up gradually indoors. After entering the room, put it in moistureproof box to absorb water.
