Intermediate Photography: Lesson 4 Quiz

You are taking a portrait and want a very blurred background. Which combination of settings will produce the shallowest depth of field?

f/11, 35mm lens, subject 5 meters away

f/2.8, 85mm lens, subject 2 meters away

f/8, 50mm lens, subject 3 meters away

f/4, 24mm lens, subject 1 meter away

You are photographing a landscape and want everything from the flowers 1 meter in front of you to the distant mountains in sharp focus. What technique should you use?

Open your aperture to f/2.8 and focus on the mountains

Focus at the hyperfocal distance for your focal length and chosen aperture

Focus on the flowers since the background will always be sharp at any aperture

Use the widest aperture available and focus at infinity

Your portrait has a beautifully blurred background, but the blur has harsh, angular shapes in the out-of-focus highlights. What determines the quality of this background blur (bokeh)?

The camera sensor size and pixel density

The lens design, including the number and shape of its aperture blades

The distance between the camera and the subject only

The ISO setting and image processing algorithm

You are shooting at f/16 to maximize depth of field but notice your images are slightly less sharp than those shot at f/8. What is causing this?

Your camera is vibrating from the mirror slap at narrow apertures

Diffraction at small apertures softens the image, reducing overall sharpness even as depth of field increases

The autofocus is less accurate at small apertures due to less light

Your lens is not designed to shoot at apertures narrower than f/11

You have a portrait where the subject's eyes are sharp but their ears are slightly out of focus. You shot at f/1.8 with an 85mm lens from 1.5 meters. What is the simplest way to get both the eyes and ears in focus?

Move farther from the subject and use a longer lens

Stop down to a smaller aperture like f/4 or f/5.6 to increase the depth of field

Switch to a 200mm lens at the same aperture

Focus on a point between the eyes and ears instead of directly on the eyes

What is focus stacking, and when would you use it?

Taking multiple photos at different focal lengths and combining them for varied perspective

Combining several images focused at different distances to create a final image with greater depth of field than a single exposure allows

Using multiple cameras at once to photograph the same subject from different angles

Stacking neutral density filters to shoot at wider apertures for shallower depth of field

You are photographing a group of 10 people arranged in three rows. Some people in the back row appear slightly soft. You are shooting at f/4 with a 50mm lens. What should you adjust?

Switch to a wider-angle lens at the same aperture

Stop down to f/8 or narrower to increase depth of field enough to cover all three rows

Move closer to the group so the autofocus is more accurate

Increase your shutter speed to eliminate any camera shake

Which factor has the LEAST impact on depth of field?

The aperture setting (f-stop)

The distance between the camera and the subject

The ISO sensitivity setting

The focal length of the lens

You are shooting a product photo of a small watch. Even at f/16, the depth of field is not sufficient to keep the entire watch sharp. Why is the depth of field so shallow?

Small apertures do not work well with artificial lighting in studios

At very close focusing distances, depth of field becomes extremely thin regardless of the aperture

The watch is too reflective, which confuses the autofocus and causes soft areas

Your camera sensor is too large for this type of photography

A friend wants to take a portrait where only the subject is sharp and the background is as blurred as possible. They only have a 50mm f/1.8 lens. Besides opening the aperture to f/1.8, what else can they do to maximize background blur?

Increase the ISO to the maximum setting

Move the subject farther away from the background, which increases the blur of out-of-focus elements

Switch to a smaller sensor camera for more apparent depth of field

Use a slower shutter speed to introduce motion blur in the background
