###trip# Winter splashing into ice - in fact, the principle is the same as the formation of the cloud, a process from unsaturated to saturated, and then precipitated. Theoretically below 0°, as long as the water is cooled in the air for a long enough time, the lower the air temperature, the faster the freezing will occur. The air should be relatively dry and cold, at least minus 20°. In order to ensure that the shooting effect is as cold as possible, we are taking pictures with life at minus 40 degrees.
