While it is true that lights can basically be bright or, dim, for a professional photographer, it is equally essential to dwell on the grey areas as well. This mainly involves, changing the strength of the lights, making it brighter or, softer with external aid and tools. Using backdrop stands can be suggested. But, it is necessary to first learn about the properties of lights while being used for photography, and the effect that it has on the object that has to be shot in film.
1.) The first and perhaps the most important property of light when it comes to photography is the fact that, brighter and harsher lights do not always contribute to good photographs. In fact, harsh lights are bad for pictures. Such lights usually cast dark shadows and can cause uneven effect like, bright in certain places and dull in the others. Soft lights on the other hand is good for professional, or, for that matter, any kind of photography. These lights do not cast dark shadows or cause uneven illumination. If you have to make it big in professional photography, the first thing that you will need to learn is about identifying and creating soft light effect for photographs.
2.) The next thing that you need to remember is about closeness to the source of light. If the light source is physically close to the object to be photographed, the softer it will be. If you walk into a studio, you will see that the light sources are kept close to the object for perfect photography lighting.
3.) Diffusion is a great way to help in making softer lights. To diffuse harsh lights into softer ones, you will only have to make it bounce off a matt surface. This could be an opaque wall, the ceiling etc. Professional photographers in studios are also seen to use white fabric sheets and translucent plastic material to cause the harsh lights to diffuse and form soft lights.
4.) Professional photography often emphasizes on texture. Enhancing texture of the object is usually a matter of concern. For this, front lighting may not be the best idea. Lighting from the side, top etc can bring out the texture of the object well. One can use this for the purpose of photographing a pet.
There are many other aspects of photography lighting and learning never seems to end. The more you photograph, the more you understand the idea of lighting in photography. However, one can make a decent start with the provided tips.
