The Exposure Triangle
For this assignment I had to define the exposure triangle and it's effect on photographs.
Shutter Speed:
- Shutter speed is the length of time that your camera's shutter stays open letting light fall on the sensor.
- The longer the shutter is open for the more exposed your photograph is - meaning that it will be brighter.
- A long shutter speed will make your photograph brighter, but if your subject or you is moving then your photograph will blur (For long shutter speed use a tripod.)
- My camera's Shutter Speed range is 15 seconds to 1/1600
Aperture:
- Aperture is how wide the opening in your lens is that lets light through. Often measured in F-Stops, the smallest F-Stop number is the widest the lens can go and the highest F-Stop number is the smallest the hole can close to.
- A Low F-Stop number or a wide aperture (the same thing) will let more light into your camera. A high F-Stop number or a small aperture will do the opposite
- A Low F-Stop will make the photograph brighter, however it will make your field of depth shallow. The opposite will happen with a high F-Stop.
- My camera's Aperture range is F3.4-F5.8
ISO:
- ISO is the sensitivity of your camera's sensor to light
- The higher the ISO, the more sensitive your camera is to light, thus meaning the higher the ISO the more the photo is exposed
- A high ISO will increase the amount of "noise" in your photo, making it less sharp and making it more fuzzy
- My Camera's ISO range is 80-3200
