Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

A light meter is used to measure the amount of light falling on the subject, determine the correct exposure settings for the camera, and ensure that the light source is not harmful to the archival materials. By using a light meter, photographers can minimize the risk of overexposure, which can cause fading and discoloration of the materials.

Multiple choice

What is the purpose of using a neutral pH buffer in the storage of photographic materials?

  1. To prevent the formation of acids and bases

  2. To neutralize existing acids and bases

  3. To absorb moisture from the environment

  4. To provide a barrier against light and oxygen
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A neutral pH buffer is used in the storage of photographic materials to neutralize existing acids and bases, thereby preventing the deterioration of the materials. Acids and bases can cause fading, discoloration, and other forms of damage to photographic materials over time.
