2 Camera Basics and Composition Free Online FlashCards

What is a practical advantage of phones and compact cameras?

Phones and compact cameras have built-in lenses and are convenient for quick, lightweight shooting, though their controls and lens options may be more limited.

How does focal length affect the angle of view?

A shorter focal length includes more of the scene; a longer focal length narrows the view and makes distant subjects appear larger. Sensor size also affects the precise view.

How does aperture relate to f-number and light?

A lower f-number means a wider lens opening and more light; a higher f-number means a smaller opening and less light. Aperture also affects depth of field.

What is the difference between autofocus and manual focus?

Autofocus lets the camera set focus; manual focus lets the operator adjust it.

How do wide and medium shots differ?

A wide shot shows a person and much of the surrounding place; a medium shot shows them roughly from the waist or chest upward.

How does a DSLR differ from a mirrorless camera?

A DSLR uses a mirror and optical viewfinder; a mirrorless camera does not. Both usually accept interchangeable lenses and offer direct exposure and focus control.

What distinguishes a prime lens from a zoom lens?

A prime lens has one focal length; a zoom lens covers a range of focal lengths.

What changes when you move the camera versus zoom?

Moving the camera changes perspective; zooming changes the lens’s angle of view.

How does shutter speed affect motion blur?

A faster shutter speed reduces motion blur. A slower speed lets in more light but can make movement blur.

What is a trade-off of raising ISO?

Raising ISO can help in low light, but may add visible image noise. Lower ISO generally preserves cleaner quality when enough light is available.

What does exposure compensation do?

Exposure compensation asks an automatic exposure system to make the image brighter or darker.

When is continuous autofocus useful?

Single autofocus suits relatively still subjects; continuous autofocus is useful for subjects that move.
