4. The term to describe the combination of aperture and shutter speed that can be changed by moving them in opposite directions.

Reciprocal relationship
Aperture - focal length - and distance to the subject
24 bits per pixel (8 per color) - which gives 16 -777 -216 colors

5. How does 'unsharp mask' work?
Through the Lens. A camera that can automatically control flash exposure using sensors inside the camera.
Follow focus
1) Use a shorter focal length; 2) Move farther away from the subject
It emphasizes the edges between tones. A threshold of zero affects all pixels - a higher threshold affects just the edges with high tonal difference and minimizes noise.

6. Using this kind of automatic exposure setting on the camera - you set the aperture and the camera sets the shutter speed.
Aperture-Priority
Sensor size - the larger the sensor size - the longer the focal length of a normal lens. (Corresponds to a diagonal line across the frame)
Add blue
Memory card / flash card / compact flash card

Depth of field
International Organization for Standardization

12. How can you change the brightness of the background when using flash?

Variations command
Follow focus

14. A ring of thin - overlapping leaves located inside the lens is called what?

18. If you must move to reduce the amount of flash reaching your subject - how far do you move?
A light-sensitive cell or sensor inside a flash unit that measures the amount of light reflecting off a subject when a flash is used.
To create a 1-stop difference - multiply the original distance by 1.4. Example - if you were originally 5 feet away - a 1-stop difference would have you step back to 7 feet.

bend toward each other and converge at the focal point.

19. An in-camera reflected meter reading a very light toned scene indicates an exposure of 1/250th at f/8. For a correct exposure - what should you do?
