I had Emily (the subject) pose in front of these doors so I would be able to focus on her while achieving a blurry background using a low aperture.
2) f/7.1 1/100 ISO 800
Using a medium aperture and a higher shutter speed, I was able to capture - without blur - Emily doing a C Jump.
3) f/5.6 1/100 ISO 400
With the ISO on the low side, I was able to capture Maria's eyeball without any pixels.
4) f/5.6 1/60 ISO 800
I set the camera on the Tv setting (this sets the shutter speed for me), set the aperture, and the self timer (10 seconds). I put it on the stairs and was able to capture a selfie with blurred motion.
Summary of Camera Knowledge
- Aperture is the size of the opening in the lens
- measured in "f stops"
- Shutter speed is the amount of time the shutter is open
- measured in seconds
- blur is not always bad
- ISO is the measure of a digital camera sensor's sensitivity to light
- the higher the ISO the more grain is present in the image
- Exposure triangle is when all of these are balanced
