DSLR. Class notes

DSLR: Digital Single Lens Reflex

A camera is a light tight box with a hole in it.
The thing in the world that makes that photographs is the light.

2 main things you balance with light on your camera: Aperture and shutter speed
So altogether it will be 3 main things: Light, aperture and shutter speed.

ISO


ISO: The way the camera measures light. how sensitive your camera is going to be

Lower ISO-less sensitive, so low ISO like 100
Higher ISO-It's sensitive a lot, so high ISO like 400

Smaller the hole, less light, blurry the photo, Deep DOF (everything in focus)
Bigger the hole, more light, moving image photo, Shallow DOF (Focus on one thing)

100-200 ISO if outside
400- ISO if inside

higher the ISO, gets grainy, gets noisy but smooth.

LIGHT LIGHT LIGHT is telling us what we need for an ISO

Day time-low ISO
Night time- High ISO

APERTURE:
if photos are dark need more light, so aperture goes high.

WHITE BALANCE:

A camera sees colour. It sees less than a human eye.

All light is colour.

Tungsten: Yellow
florescent:Green
daylight: Blue


Opposite colours
Red-Cyan
Green-Magenta
Yellow-Blue

So if there is to much red you have to take out the opposite colour, cyan. (something like that)
