Iso: how sensitive your camera is to light.

– 100 iso is bright light (most scenarios)

-3200 iso is low light

Shutter speed:

  • 1/1000 of a second = fast
  • 1/60 of a second = mid range
  • 1 of a second = slow

* higher shutter speed- fast sports, live bands and fashion catwalks.

*slower shutter speed- moving clouds and moving water.

Aperture: how wide open the lens is.

*wide= F1.4

*small= F16

-The scale:


*lower aperture are good for portraits. Has a shallower depth of field (focus)

*larger aperture are good for landscapes, everything is in focus. Greater depth of field.
