Exploring the Built-in Light Meter - Classwork
1. What is the difference between an incident light meter and a reflective light meter? Which is used in the DSLR camera?
Incident measures illuminance and reflective measures luminance. The DSLR has a reflective light meter because it can't be pointed towards the sun.
2. Describe how a center weighted meter works.
The meter averages all the light in the area or picture but weighs its average to give more emphasis on the center.
3. What lighting situations can cause the cameras light meter to not work properly?
There are two lighting situations one is a subjects against a much lighter background, and second it's a subject against a much darker background. A snowy scene, contrasty picture.
4. What are the steps to over come a misleading reading?
a. Move in close to meter a subject against a much lighter background.
b.Tilt the meter down to exclude a bright sky when you meter a landscape.
5. In a reflected light meter, what is the tonal value the meter “see” and recommends as the exposure?
The "middle gray" shade is what the camera misreads it for and often meters the whole portrait off of that.
6. Explain in your own words how to make a white object white when using an averaging meter?
You need 2 stops more of exposure.
7. Explain in your own words how to make a black object black when using an averaging meter?
You need 2 stops less of exposure .
