TED-Ed: How to take a great picture - Carolina Molinari

The video tutorial explains the fundamentals of digital photography, focusing on how cameras work with light to create images. It covers three key variables for correct exposure: aperture, shutter speed, and ISO sensitivity. The tutorial describes how each variable affects the final image, such as depth of field, motion blur, and image noise. It also introduces the light meter as a tool for achieving proper exposure. The video encourages viewers to practice taking photos under various conditions to master these concepts.

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

• Aperture, Shutter Speed, ISO Sensitivity

• Aperture, Focal Length, White Balance

• Focal Length, ISO Sensitivity, Aperture

• Shutter Speed, ISO Sensitivity, White Balance

How does a large aperture affect the depth of field in a photograph?

• It increases the depth of field

• It decreases the depth of field

• It has no effect on the depth of field

• It makes the entire image blurry

What does a lower f-stop number indicate about the aperture size?

• The aperture is closed

• The aperture size is unchanged

• The aperture is larger

• The aperture is smaller

What is the effect of using a faster shutter speed?

• It allows more light to enter

• It makes the image darker

• It reduces motion blur

• It increases motion blur

How does increasing ISO sensitivity affect image quality?

• It reduces noise in the image

• It increases noise in the image

• It makes the image sharper

• It has no effect on image quality
