Photography fundamentals.

I use a FujiX100T for all of my photography. The photos are stored on an SD Card and later copied to Trabant using a bash script and rsync.

The three pillars are Apterture (Blende), Shutter Speed (Verschlusszeit) and the ISO value. All three influence the brightness of the image and need to be balanced with another.

Aperture

The size the lens is opening, controlling how much light enters the camera.
Represented through the f-stop value:

Shutter Speed

Duration the camera shutter is open, exposing light onto the sensor, measured in fractions of a second.
Longer - motion blur
Shorter - freeze motion

ISO

Originally defined film sensitivity but is now used to handle the brightness of the image.
Higher ISO increases brightness, but adds more noise.
Lower ISO creates a darker image, but with less noise.
