Exposure Triangle

3. a.k.a decreasing the exposure
4. the aperture functions similarly to this function of the human body
6. ISO that is best used in low light situations
9. a high ISO introduces this to your image
11. is controlled when changing the focal length/zoom
14. this type of f-stop means larger opening creating a shallow depth of field
15. this type of lens means an aperture can open up very wide

1. a.k.a increasing the exposure
2. a factor controlling DoF
5. ISO that is best used in well lit situations
7. another factor controlling DoF
8. depth of field when both close and far images are out of focus
10. depth of field when the subject is in focus but the background isn't
12. the way which aperture is measured
13. this type of f-stop means there's a smaller opening creating a deeper depth of field
