Backlight is unbeatable for silhouettes and creating halos....Therefore compositional lighting may differ from frontal flat lighting to side lighting....As u r aware, without light, there is no photography....The camera is the source to capture the objects you select under various lighting conditions. Not only straight, but by manipulation the lights, the objects can be revealed or hidden...Tones can be changed....colours can be changed altered or replaced.Light may be soft and hard.
Intensity can differ to affect the exposures...Therefore light is more intense on sunny days than overcast days.
The light changes according to season...In summer it is harsh, while in winter it is more beneficial for purpose of photography, since for four to five months the sun is angled and providing straight but softer directional light, like a spotlight in a studio, as happened in the enclosed photograph......I was attracted by the shadow of the tree and it was purely coincidence that as I clicked the dog has reached the centre point and made a good subject with directional haloed light with its shadow contrasting with the shadows of the tree which brings the eyes back to the dog.
Yes u can shoot pictures throughout the year..but as I experienced and photographed even good portraits in the evening or morning light of winter.....Still some more days are left before the sun goes head high and the halo effect or as called rim lighting can be achieved only after eight months, outdoors.
