Digital Photography Basics

What are the 3 variables in the exposure triangle?

• Aperture

• Shutter Speed

• ISO

What happens during a long exposure?

• More light and motion captured

• Darker image and less motion blur

What is the effect of shallow depth of field?

• More light and background blur

• Less light and sharper background

What does a higher ISO setting result in?

• Less light and noise

• More light and noise

What is exposure in photography?

• The amount of light captured by the sensor

• The distance between the sensor and light

What does auto white balance do?

• Adjusts the white balance by adding orange or blue

• Keeps the color temperature constant

What is focal length in photography?

• A measurement of the actual length of a lens

• A calculation of optical distance

What is the purpose of using a polarizing filter?

• To reduce reflections and enhance colors

• To increase exposure time

How does aperture affect exposure?

• Wider aperture allows more light

• Narrower aperture allows more light

What is the role of shutter speed in photography?

• Controls the duration of light exposure

• Determines the color balance of the image
