Black and White Photography Questions

1) Three basic elements of a camera:

Lens (optical element)

film (chemical element)

camera body (mechanical element)

2) Single-Lens- Reflex (SLR) Camera:

Photographer sees the same image that's exposed to the film

Doesn't need electricity to take picture

3) Aperture:

controls amount of light that reaches the digital camera sensor

opens wide when light decreases and closes small when light is bright

4) Shutter Speed:

setting that controls the length of time the shutter is open (letting light in camera)

can be a fraction of a second or multiple seconds at a time

5) Three things that need to be balanced for exposure:

aperture, shutter speed and ISO/film speed

6) On a sunny day you would use low film speed because of the constant brightness.

 

7) Four steps to developing black and white film:

place film on developing agent

rinse film with water or a "stop" bath

unexposed silver-halide crystals are removed in fixing bath

wash film with water to remove processing chemicals. Film strip then dried and individual exposures are cut into negatives

8) Things needed to make black and white prints:

dark room

developer tray

stop bath tray

fixer bath

water bath

hanger to dry pictures

9) Back and white image material is actually silver.
