Night and Low Light Photography

You have two options to shoot in night or low Light;
one way is to use the artificial light which is your flash light, the other way is to use a long exposure.
Using a tripod helps to steady your camera and to avoid to get blurry pictures by moving the camera.
You should take night or low light picture in manual mode, because of the lack of light, auto mode might not work as well.

Light

Light is in charge of making elements of line and shapes visible in photography.
It also does the contrasts in pictures(color and brightness).

Each color has a meaning and expresses emotions in pictures. Usually light colors are there for happiness etc. and dark colors for sadness and fear.

Lenses zoomed out - zoomed in





Lenses


        All lenses affect: focus, film exposure, angle of view and depth of field
The main types of lenses are:
        - The camera lens is located in the front of the camera body and gathers the light from the subject. It allows you to focus and controls the light that reaches the film.
        - The fixed lens is permanently attached to the camera body. Most cameras with a fixed lens are compact and have limited versatility.
        - The interchangeable lens is removable and you can replace it with other lenses for wide range of use.

White Balance

The White Balance setting makes sure that a white colored space in your picture looks as white as it really is or not is.
For pictures see 'White Balance' post -> October 30th

ISO and File Size


ISO -International Organization for Standardization
  • measures how sensitive the film is to light.
  • When you are trying to take a picture in the dark you should use a high sensitivity.
    PROBLEM: with a high ISO the picture will have a lot of visual noise what makes the picture grainy and lower quality.
  • You should use a low sensitivity when you are taking a picture in the brightness because the daylight already gives light to images.

File Size

  • File Size includes Resolution.
    Resolution is the width and height of a picture.
  • It also includes the pixels in the image.
    Having more pixels -> picture can be larger without getting grainy
