Winter landscape. Fish-eye lens view of snow- covered trees under a blue sky. The horizon forms a circle,giving the picture a spherical appear- ance. The dark area in the sky is produced by use of a polarising filter,which blocks out light polarised in certain directions. Polarisation of light is caused by dust particles scattering sunlight as it crosses the atmosphere. Although invisible to the human eye,polarised light can be seen by some flying insects,which use it to help them navigate | |
