Understanding Camera Exposure

The video tutorial explains the basics of how cameras work with light to create images. It covers three main variables that affect exposure: aperture, shutter speed, and ISO sensitivity. Aperture controls the amount of light entering the camera and affects depth of field. Shutter speed determines how long the camera's sensor is exposed to light, influencing motion blur. ISO sensitivity adjusts the sensor's sensitivity to light, impacting image noise. The tutorial also introduces the light meter, a tool to measure the correct exposure. Viewers are encouraged to practice using these settings to improve their photography skills.

What are the three variables that determine the correct exposure in photography?

• Aperture, Focal Length, ISO Sensitivity

• Aperture, Shutter Speed, ISO Sensitivity

• Shutter Speed, Focal Length, White Balance

• ISO Sensitivity, White Balance, Focal Length

What happens to the depth of field when the aperture is large?

• It becomes shallower

• It becomes blurry

• It becomes deeper

• It remains unchanged

How is aperture size measured?

• In millimeters

• In f-stops

• In ISO numbers

• In seconds

What is the effect of a slower shutter speed on a photograph?

• Decreased depth of field

• Increased motion blur

• Decreased light exposure

• Increased sharpness

For capturing fast-moving subjects, which shutter speed is preferable?

• Higher ISO

• Longer exposure

• Faster speed

• Slower speed

What is a creative use of long exposure in photography?

• Portrait photography

• Light painting

• Macro photography

• Sports photography

What does a higher ISO setting allow you to do?

• Decrease shutter speed

• Reduce image noise

• Capture images with less light

• Increase depth of field

What is a downside of increasing ISO sensitivity?

• Longer exposure times

• Deeper depth of field

• Noisier images

• Sharper images

What tool helps photographers determine the correct amount of light for exposure?

• Tripod

• Light meter

• Flash

• Lens hood

Why is it important to practice taking pictures under different conditions?

• To reduce camera weight

• To understand camera settings

• To improve camera battery life

• To increase camera resolution
