Exercise 1: Understanding the effects of ISO on exposure
Here we go with the first exercise... I hope this is clear as a whistle.
I think everyone shoot manual, right?
If not, set your camera to "M" manual mode.
- set your aperture to f8.0
- select the lowest ISO in your camera can go for instance ISO 100
- adjust the shutter speed until a correct exposure is indicated in the viewfinder, meter will be at "0" or center (+|||0|||- in the viewfinder - canon will be the other way around)
- take a picture of a non-moving subject, you can use a tripod if necessary
- begin to increase your ISO
- do not change your aperture, leave to f8.0
- adjust your shutter speed to obtain the correct exposure
- take the picture
- repeat exercise for each ISO available
Extra credit: Repeat exercise but keep SS constant. You ca post this if you want.
