Sad Okey dokey.  I suppose I ought to have posted in chapters Cheesy

The term "exposure" refers to a combination of aperture and shutter speed.
Aperture: A setting to determine how wide the opening inside your lens is.  Controls how much light gets through to the sensor.
Shutter Speed: The amount of time that the image sensor (or film) is exposed to light.  Controls how strongly the image is imprinted--longer time leads to brighter images, overly-long times can lead to over-exposed images.
Film Speed: A rate measurement that determines how sensitive your image sensor is to light

So, by tweaking any of these settings, the photographer can select how much light gets through, how long it "paints" onto the film, and how much of an effect that "paint" (light) has on the overall image.

For details regarding the choices involved, the why and how, "night-mode," and all other erata, well--that's in the looong post Smiley

These are a bit of an example of 'night mode' which utilises an extended shutter speed.
Sorry if they're a bit large.
