Lighting
If light did not exist, neither would photography. Photo is Greek for 'light', before attempting to understand photography, you must first understand light. Even the most recent and highly sophisticated cameras combined with the most expensive and sharpest lenses, would all be completely useless without light as it would be impossible to take a photography.
To understand why light is important in photography, you must first understand how an image is captured to your film. The film which is placed in to cameras is something called photosensitive material. Film is basically material that reacts i a way that when light hits it, an image is formed. However, until the film is processed or developed, the images cannot be seen.
Light is a form of electromagnetic radiation which travels in waves and is emitted and absorbed in tiny packets called photons. Light exhibits properties of both waves and particles, this is reffered to as wave-partical duo.
White light is formed of the seven colours of the spectrum. When white light hits an object, six of the seven colours are absorbed and one is reflected, the one colour which is reflected is the colour which me see.
How A Photo Is Taken
The process of capturing an image begins my the shutter release button being pressed down, which opens allowing light through the hole, depending on the light available, depends on how long the shutter will be open. If a lot of light is available, the shutter will open and close quickly, oppositely if minimal light is available, it will stay open for longer. Once the shutter has closed, the light which has been allowed in hits the photographic film at the back of the camera creating an image. When the shutter release button was intentionally pressed, whatever was in the field of view at the time of pressing is what was captured by the light and film. Once the photograph has been captured it can then proceed to become developed, amplified or modified.
