Understanding Digital Cameras and Photography

Kamri introduces digital cameras and meets Tom, a photo engineer from National Geographic. Tom explains how cameras capture light through the shutter and record images as electrical signals. They discuss resolution and how motion can cause blur in photos. The video concludes with a call to action to explore more content.

How does the camera sensor perceive light?

• As electrical signals

• As sound waves

• As heat

• As magnetic fields

What is the role of pixels in a digital camera?

• They control the camera's zoom

• They represent the electrical signal of light

• They determine the camera's weight

• They store the camera's battery

What does the camera do with the electrical signals it collects?

• It uses them to charge the battery

• It encodes them as data

• It converts them into sound

• It discards them

What is meant by 'resolution' in digital photography?

• The size of the camera

• The speed at which a camera can take photos

• The detail a camera can render from light

What can cause a photo to appear blurry?

• Low battery

• Too much light

• High resolution

• Subject moving too quickly for the shutter

How can you reduce blurriness in a photo?

• Use a larger camera

• Decrease the resolution

• Take photos in the dark

• Increase the shutter speed

What should you do to learn more about how things work?

• Read a book

• Visit a museum
