This section covers optical effects in water drops, ranging from the microscopic drops in fog and cloud to the large drops in rain, falling spray and morning dew.

Most of them involve sunlight and water but some are bright enough to be seen by moonlight. No optical aid is necessary though a polariser can be useful for some of them.
