Aperture & Depth of Field Definitions

1. List Standard Aperture/F-stops from brightest exposure to darkest-

2. Aperture Priority- Selects a shutter speed to match. The camera will ensure proper exposure. Shutter priority is where the user picks a shutter speed with the camera selecting the aperture to match the program's mode.

3. Ambient Light- General lighting, Comfortable level of brightness

4. Artificial Light- Light that is not natural (Room Light)

5. ASA/ISO/Film Speed- Film speeds, 100 speed film is “slow” or not very sensitive, it needs a lot of light to make an exposure. 3200 speed film is “fast” or very sensitive.

6. Bracket- Taking several shots of the same subject using different camera settings

7. Depth of Field- The distance between the nearest and farthest objects in a scene that appear sharp/clear in an image

8. Exposure Triangle-  the 3 element are needed

1. ISO – the measure of a digital camera sensor’s sensitivity to light
2. Aperture – the size of the opening in the lens when a picture is taken
3. Shutter Speed – the amount of time that the shutter is open
   
   a change in one of the elements will impact the others.

9. How to Control Depth of Field- The image you normally see through the viewfinder or on the Live View screen is displayed at the lens’s maximum, or widest, aperture. Pressing the Depth of Field or preview button allows you to view the scene at the working aperture, so that you can see what areas will appear sharp. There’s a range of ways to control the depth of field – the choice of aperture, focus distance and the type of camera. 

10. Light Meter- device used to measure the amount of light

F 4 and F 16
