"Put light against the light - you have nothing Put dark against dark - you have nothing Its the contrast of light and dark that give each other one meaning."
In photography lighting is one of the key factors of creating a amazing picture. It also creates everything we see and inspiring affects. So, when taking a picture the photographer has to pay attention and be careful at their choices on their camera to capture ideal amount of light to get a fantastic texture and vibrancy.
The important thing that everyone should know is that what we see is created by light reflecting off objects and traveling into our eyes. How a photograph is the same. A photo is made of light reflecting off of objects, causing the light to travel into the camera, where it is captured by film or a digital sensor.
Exposure: It’s the overall brightness or darkness of a scene. A natural or normal exposure is when a photographer takes a picture that is close to how a human sees the scene with their own eyes. Quality: Light can be described as light or dark but it is also described as soft or hard. This means that when there is a lot of light near to the object, the light helps create a very soft picture. A hard picture is when there is a small ball of light far from the object, creating a hard picture with well defined shadows. Direction: As we all know light travels in one direction. I maybe hard or soft but the sun is a single light source and that light travels in straight lines radiating out from it.
Colour: Colour is also one of the key things in photography but colour does link into light a getting a good picture with a soft lighting also means great colour in the pictures. Colour can also be changed when editing, this is called changing the temperature. Highlight: The highlight is the brightest part of an image. When we are dealing with a single light source this is normally a reflective surface or object facing the light source. Shadow: Shadow is the darkest part of an image. When we are dealing with a single light source this is normally a non-reflective object or surface facing away from the light source or in the shadow of something else.
Contrast: Contrast in an image is the measurement of the difference between the highlights and the shadows. If there is a lot of range between the two there is very little contrast, if there is little range between the two then an image is said to have high contrast. Images shot on a cloudy day usually are low in contrast, and images shot in the bright sun are generally high in contrast Light travels as transverse waves and faster than sound. It can be reflected, refracted and dispersed. Ray diagrams show what happens to light in mirrors and lenses. Eyes and cameras detect light. A ray diagram shows how light travels, including what happens when it reaches a surface.
When light reaches a mirror, it reflects off the surface of the mirror: 1.the incident ray is the light going towards the mirror 2.the reflected ray is the light coming away from the mirror refraction, refraction is when an object changes direction after placing it in a liquid e.g water.
