Camera Questions

Scope

Photography is a technological field of endeavor, and without that background, the photographer is limited to either being controlled by their camera or at the mercy of luck. Right now, you are stuck TAKING pictures. You need to move towards MAKING pictures. Do you understand the difference?

This is all written work. Your answers should be easy and clear, such that ANYONE, especially you, can understand them. You need to have this stuff firmly in your head. This is due as a blog post no later than Wednesday, 10/3 at midnight. Be prepared for an oral examination with me on Thursday, 10/4.

If you have problems getting to information that seems relevant, add the word "Camera" to your search phrase.

Define these:

ISO Speed- adds or takes away light to or from an overexposed or underexposed photo. Affects the sensitivity to light.

Aperture- the size of the opening in the lens that allowes light in. Smaller F-stop means more light allowed in, larger F-stop means less light allowed in.

Shutter Speed- the ammount of time a picture is exposed for. A faster shutter speed captures faster moving targets and makes the picture darker. A slower shutter speed is better for dark enviornments to let more light in and enables light effects, like this one:

 

Using only ONE SENTENCE, explain:

What is an exposure meter (a light meter)?

An exposure meter, or light meter, is used to measure the ammount of light in a scene to be photographed.

How does it work?

It has a sensor in it that detects the light and then tells the photographer what F-stop and shutter speed the photo needs.

What is an incident-light meter?

It measures the light in a scene and is not influenced by the reflectance of the subject being photographed. They also measure the different levels of light in a scene.

What is a reflected-light meter?

It measures the light reflecting off the subject and may vary according to variances in tone, color, contrast, background, surface, or shape.
 

What is a Center Weighted Meter?

 The meter concentrates between 60 to 80 percent of the sensitivity towards the central part of the viewfinder, and the rest is faded out to the sides.
 

What is an Evaluative/Multi-Segment Meter?

The camera measures the light intensity in several points in the scene, and then combines the results to find the settings for the best exposure.
 

What is a Spot Meter?

The camera will only measure a very small area of the scene.
 

What sort of exposure meter is on your camera?

My camera uses Multi-Segment, Evaluative, and Center weighted meters.
 

What is overexposure?
Overexposure is when the picture is too bright because to much light was let in.
 

What is under exposure?

Under exposure is when not enough light is let in, making the picture too dark.
 

What is depth of field?

Depth of field is when one object is in focus and the area around it is blurry.
 

Write as much as you need to, to explain:

What is the relationship between aperture, shutter speed, and ISO?

 a higher ISO, and lower shutter speed and aperture makes a lighter picture, and the reverse makes it darker.

What is exposure compensation?

Exposure compensation is a setting that enables you to higher or lower the brightness or darkness of an image, when changing the aperture, ISO, and shutter speed isn't enough.
