PRINCIPLES OF PHOTOGRAPHY
Photography simply means writing, drawing or printing with light. Light is therefore most fundamental in photography because without it then no photographs will be produced.
Light is a form of energy, it’s a source of all colors and its composed of different wavelengths, those that are of importance in photography are those that fall within the visible region of the electromagnetic spectra because they can be perceived by the human eye. These are composed of different colors e.g. red, blue green yellow orange etc.
Light is naturally ‘white light ‘but objects around it normally absorbs some wavelengths and reflect others, transparent materials transmits all wavelengths equally unless they are colored but colored objects reflect some colors and absorbs others. This selective transmission of light is important in photography, it is in fact the only way in which different tones are produced and this normally determine the way we perceive the shape and forms of objects.
