Final Exam Flashcards
Which of these shutter speeds is the minimum recommended when handholding a 50mm lens?
1/60
What is an advantage of using a tilt-shift lens like the bellows of a 4x5 large format camera?
Using a tilt-shift lens may bring required zones of subject into focus, improving effective depth of field. Tilt shift lenses are useful for taking building photography. The lens can shift to allow the back of the camera to be parallel with the building. This allows for less distortion of the image when shooting buildings and larger effect depth of field.
Which attribute does NOT affect depth of field?
ISO Setting
The resolution of a 4 x 5 inch film camera is approximately ______ times larger than the resolution of a 35mm film camera. This makes large format easy to enlarge to 16 inches x 20 inches and beyond.
13x
Another term for a large format camera is a ______ camera.
view
What principle is illustrated by this picture? The principle is often used for depth of field control by large format cameras and mimicked using a Lens Baby.
Scheimpflug
On medium format cameras, prime lenses typically have a maximum aperture of ______.
f/2.8 or f/4
Like the example above, storytelling with a digital compilation of pictures into one finished piece is called ________?
montage
What are the factors to decide when to use 35mm, medium format, and large format photography equipment setups?
The larger the camera format, the better the quality. When having a medium or large format cameras, the lens quality must be better too.
35mm is most portable and affordable and used in photojournalism and documentary photography.
Medium format cameras are several times more expensive than 35mm.
Larger format cameras require more light because they have narrower depth of field.
Larger format cameras are used mainly used in studios were large size output is needed.
What are the two missing complete apertures in this group?
f/2 and f/5.6
For the same angle of view as a 50 mm lens on a 35 mm format camera, a 4x5 large format camera will be a _______ lens for the same angle of view.
150 mm
Professional architectural photography use large format or tilt shift lenses to correct __________.
converging verticals
According to the 35mm film or full-frame digital standard, a 50 mm lens on a 1.5x crop factor camera will be effectively ______.
75 mm
What technique is being used here to maximize the depth of field?
Hyperfocal Focusing
A _________ lens will exaggerate the perception of visual depth.
wide angle
A telephoto lens does what to an image?
compresses the distance
Which of these factors does NOT affect a photograph’s depth of field?
ISO / Grain Size
When all exposure settings are the same, a compact sensor size camera will produce ________ than a full-frame sensor camera.
greater depth of field
When all exposure settings are the same, a compact sensor size camera will produce ________ than a full-frame sensor camera.
greater depth of field
The birth of digital still cameras as we know them today happened in ________.
1988
Define resolution in detail. What is interpolated vs. optical resolution?
All film and digital use resolution as a measure of detail. It defines how sharp your images will appear and what level of fine detail will be represented. Anything placed over the lens or sensor may affect the quality of the resolution. The resolution of the sensor is the ultimate limiting factor but the quality of the lens is important to the loss of sharpness. Technically most digital cameras only record one color per pixel and interpolate the other two colors.
Megapixel alone is not the primary measure of resolution. The highest number of megapixels does not necessarily represent the highest quality or automatically mean that the largest level of detail will be reproduced. The detail is inherent of the quality and size of the sensor. The pixel “pitch” relates to the overall size of the pixels.
Shooting close to a subject with a wide angle lens does what to a subject?
isolates from the background
Which of these files will be the smallest digital file type for saving a photograph for a website?
JPEG (low-medium quality)
Explain Perceptually Lossless image files compared to Lossless image file formats.
Perceptual lossless means the compression quality is virtually impossible for the naked eye to tell the difference between the compressed version and the original image. There is still information being lost but the difference will only become apparent if more edited is done.
Lossy compression methods work on the principle that some of the information in an image is less visually important, or even beyond the limits of the human visual system and use clever techniques to remove this information, still allowing reasonable reconstruction of the images.
Under normal daylight conditions, the human visual system needs the tonal range from shadow to highlight to be divided between ________ different tonal values to see continuous tones in a photograph. Fewer tonal values and the image will appear posterized, an image artifact that is a result of insufficient sampling.
140 and 190
A 5 MB 8-bit depth file when converted to a 16-bit depth will be ______.
10 MB
What photography technique allows all distances to be acceptably sharp?
pinhole
Which file type will require the largest file size using a digital camera?
TIFF
As any light source is moved away from the subject, the light becomes _______________.
harder
The file size on computers is calculated in bits and bytes. What is the appropriate way that file sizes are represented?
8 bits = 1 byte, 1,024 bytes = 1 KB, 1,024 KB = 1 MB
Which file type cannot be saved as a 16-bit depth file?
JPEG
If the aperture setting changes from f/8 to f/16, what does the change look like on the exposure?
two stops darker
Light travels in ___________.
straight lines
An f-stop which would admit a large amount of light into the camera and produce very little depth of field would be:
f/2
After stitching the pictures together in Photomerge, with the clone or healing brush tools the non-destructive way to touch up stitching errors is on _________.
a blank new layer

1/250 at f/2.8

Which of the following are factors which control exposure?
shutter speed, aperture, ISO
When would you use and not use a tripod for the slow sync flash techniques? Give reasons for both.
When using either slow synch in either mode (or in the automatic ‘night mode’ you will want to consider whether or not to use a tripod. Traditionally when shooting with longer shutter speeds it is accepted that a tripod is essential in order to stop any camera movement. Even the steadiest of hands will not be able to stop a camera moving over even a 1 or 2 second exposure. So if you want to eliminate blur from your cameras movement definitely use a tripod (and consider a shutter release cable).
However in some circumstances hand holding your camera while using slow sync flash can lead to some wonderful effects. For example if you’re at a wedding or party and are out on the dance floor the results can be great at capturing the mood of a night with those you’re photographing largely frozen by the flash but the lights on the dance floor blurred from you moving your camera during the shot.
What effect is narratively communicated with the slow sync flash technique?
It gives a sense of surreal blurriness and frozen reality while also showing motion and excitement. Having a subject frozen with the background moving can lead to a sense of stability to the frozen subject. This technique can be used effectively in commercial, advertising photography.
What are the main two techniques professional photographers use to freeze fast-moving subjects?
shutter speed, flash
A 1:1 replication ratio refers to what type of lens?
macro
What is the process called for the panoramic camera technique used in major sporting events?
FanCam
