One of the key elements to photography is of course light. Without light one would simply have a blank image. If you enjoy landscape photography then the magic hour at sunrise and sunset are really the only times of the day for such photography. The reason being that photography is in essence about two key things composition / framing of the subject and the painting of the scene with light.
Light can be described in four different forms, transmitted, reflected, soft and hard light. The sun on a clear day is a good example of hard light as one can see really strong shadows on a summers day. Soft / diffused light is that which you would find on an overcast day with little to no visible shadows to be seen. In the case of taking a photograph of a sunset for example you also have the ability of taking in transmitted light, in the form of being able to see the light source. Should you be located close to the sea or a lake then you can also make use of the reflected light from the water.
One of the classing photographic assignments is of course Portraiture. Often you may hear that you should always shoot with the light (sun) to your back. However by shooting into the light source you can capture some wonderful colour and highlights. A large aperture lens is also great for portraiture, thus allowing for a shallow depth of field to be created and all the emphases being placed on the subject in question.
If you enjoy landscape photography then some of the videos below may be of interest.
The following video includes a number of examples of some interesting landscape shots to the music of Enya!
Its not just light but also composition that is important to any great image. You can perhaps glean a few tips on the subject of composition from the final video.
