RVPC basic photography crash course

What type of viewfinder does a DSLR have

• Optical viewfinder

• Electronic viewfinder

• Digital viewfinder

• Mirror and prism viewfinder

Which camera type has a wider variety of lenses available

• Mirrorless cameras

• DSLR cameras

What are the components of the exposure triangle

• White Balance

• ISO

• Aperture

• Shutter Speed

What is camera noise

Select a statement that is not true

• Slower shutter speeds allows more light to enter the camera

• Slower shutter speeds are used for motion blur

• Faster shutter speeds are used to increase exposure

• Faster shutter speeds increase subject sharpness

A larger aperture value allows lens to open wider

• True

• False

Rank the white balance settings from warmest to coolest

(List of settings: Tungsten, Sunny, Halogen, Shadow, Cloudy)

Challenging question: What is the cause of camera noise

• Camera amplifiers affecting light signals differently

• Random photons having varying incident rates on camera sensors

• Overexposure causing photodiodes to suffer from overload

• Low light situations causing signal-noise ratio to decrease

Challenging question

Why do pictures of projector screens taken using phones sometimes have black lines?

Hint: Consider shutter speed of phone cameras and the nature of their sensors
