Questions and Answers

Assuming a constant frame rate, what adjustment to exposure settings is most suitable when transitioning from a predominantly bright scene to one that is significantly darker?

  • Reduce the aperture size (higher f-number) for greater depth of field.
  • Decrease the ISO to minimize noise in the darker environment.
  • Open the aperture wider (lower f-number) to allow more light in. (correct)
  • Increase the shutter speed to capture more ambient light.

A photographer is using a handheld camera and wants to capture a sharp image of a subject moving quickly across the frame. Which setting is most crucial to adjust to minimize motion blur?

  • Aperture
  • Focal length
  • ISO
  • Shutter speed (correct)

While shooting outdoors on a sunny day, you notice that your images are overexposed. What is the most direct way to correct exposure while maintaining your desired aperture and ISO?

  • Decrease f-stop to let in less light.
  • Increase ISO to make the sensor more sensitive.
  • Increase shutter speed to decrease exposure time. (correct)
  • Decrease white balance to cool the image.
