Shutter, Aperture + ISO Basics Q&A

1. In relation to light, what does the shutter speed determined? It determines how much light hit the image sensor.
2. What is the shutter speed generally used to control? How long the shutter be open for.
3. What effects can different shutter speeds create? Freeze frame & Blur
4. Explain the difference between large and small apertures? LARGE - More light get through and is more used for focusing on a object/small area. SMALL - Less light gets in and is more used for a detailed of everything.
5. What is depth of Field? How much (area) of the image can be focused.
6. What effect does a small aperture and large aperture have? SMALL - Large depth of field LARGE - small depth of field.
7. Explain the relationship between ISO and light sensitivity? The ISO sets the image sensor's sensitivity for a "good" exposure.
8. What is 'noise' grain? How much grainy the image is.
9. Explain what "each element does not work in isolation" means? N/A
10. Explain the Exposure Triangle? The Exposure Triangle consists of 3 elements (ISO/ASA, Shutter Speed and Aperture) and this means that if you were to adjust one of the 3, you would have to ajust 1 of the others to get a 'good/correct' exposure.
