Built-In Light Meter Questions1. What is the difference between an incident light meter and a reflective light meter? Which is used in the DSLR camera?
Incident light meters are hand held, and have a much wider angle view, about 180 degrees and this measures the illuminance, the light falling on a subject. While a reflective light meter can be hand held or attached to a camera, and uses luminance reflected from an object. In a DSLR camera you would use a reflective light meter since they can be built into a camera more than incident. 2. Describe how a center weighted meter works. The center weighted meter works by averaging all the light in the scene and then weighs its average to be able to give more emphasis on the center point than its surroundings. 3. What lighting situations can cause the cameras light meter to not work properly? The lighting meters are created to help produce the right exposure, but there are cases when it doesn't. An example of this is a snow scene. The light and dark areas created an unbalanced average that leads to the meters reading the image as a middle gray. 4. What are the steps to over come a misleading reading? To overcome a misleading reading you can just do an overall reading, with an incident light meter you are reading the overall amount of light that falls on an image. These work very well for metering average scenes. 5. In a reflected light meter, what is the tonal value the meter “see” and recommends as the exposure? In a reflective light meter sees middle grey. 6. Explain in your own words how to make a white object white when using an averaging meter? When using an averaging meter to make a white object white, you would increase the exposure by two stops. 7. Explain in your own words how to make a black object black when using an averaging meter? When using an averaging meter and making a black object black, you would decrease the exposure by two stops. SunInside |
