Introduction to Photograph Exam.
A camera uses either a light-sensitive device ( ) or a digital sensor to
capture an image - Correct Ans: ✅Film
In traditional film-based cameras, the film becomes a - Correct Ans:
✅hemical record of the pattern of light on an object.
A shutter opens and closes between the____________________________ , giving the photographer
control of letting light in. - Correct Ans: ✅film and the lens
The shutter speed is - Correct Ans: ✅the length of time that light is let into the camera in order to expose the film.
Aperture is - Correct Ans: ✅the lens opening that allows us to control the amount of light that reaches the film or digital sensor.
Aperture is controlled by the _______________________ - Correct
Ans: ✅iris diaphragm
iris diaphragm - Correct Ans: ✅a set of overlapping metal plates that expand out to allow more light or fold in on each other to reduce the amount of light.
The larger the grain of the film, the more - Correct Ans: ✅quickly it will absorb the light.
The size of the grain is indicated by the film's - Correct Ans: ✅speed
100 ISO film is typically used for - Correct Ans: ✅outdoor photography where the sun is bright
1600 ISO film is used - Correct Ans: ✅where light is very dim
When you point the camera at your subject, light bounces off the subject and enters the camera. The light passes through the lens and onto a mirror, located between the lens and the shutter. This mirror reflects the light upward to a _______________________
The light from the image then bounces off this mirror and into the
viewfinder, where you see the image - Correct Ans: ✅pentaprism
pentaprism is a - Correct Ans: ✅five-sided mirror
The job of the pentaprism is to - Correct Ans: ✅flip the light from the image so that the image appears right side up.
One of the earliest cameras made was a - Correct Ans: ✅pinhole camera.
A dSLR is a - Correct Ans: ✅a digital version of the traditional SLR camera.
Digital cameras - Correct Ans: ✅. use an electronic image sensor to digitally record an image
. record the image to a memory device, or card . produce photographs that are made up of pixels.
takes a picture and saves it in a particular file format, which organizes and stores the information from the photograph
(1 )A digital camera and a traditional film camera are similar, except
(2)Another difference between digital and traditional film cameras is
- Correct Ans: ✅( 1 )digital cameras use electronics rather than chemicals to record the image.
( 2 )format.
A pixel is - Correct Ans: ✅the smallest unit of the picture that can be controlled.
The number of pixels is abbreviated as - Correct Ans: ✅MP, million pixels.
Generally, each pixel in an image creates_____________ of data -
Correct Ans: ✅three bytes
common ways of storing this information: - Correct Ans: ✅JPEG
All cameras work in - Correct Ans: ✅a similar way
A photograph is created when - Correct Ans: ✅light is allowed to fall on a light-sensitive medium
How light or dark a photograph is depends on - Correct Ans: ✅how much light was allowed to fall on the light-sensitive medium
A camera is - Correct Ans: ✅a light-tight box that contains a light- sensitive material or device and a way of letting in a desired amount of light at particular times to create an image on the light-sensitive material.
In contrast, a wide-angle lens shrinks the object in front of it with a
shorter focal length. - Correct Ans: ✅magnify an image or make an object seem closer than it really is.
TIFF:
RAW:
JPEG: - Correct Ans: ✅"Joint Photo Experts Group" is the predominant default file format in many digital cameras because the file format compresses the image to decrease the size of the image which enables more storage for photos. The drawback of JPEGs is that compression causes the loss of some data. The more compressed the image, the greater loss of data, which can make an image look blurry.
TIFF: - Correct Ans: ✅The Tagged Image File Format is a lossless file format. A lossless file format keeps all of the information in the picture because it is a larger file size. TIFF files can be compressed but the size difference isn't significant.
RAW: - Correct Ans: ✅A file format that saves the actual data, which are not processed by the camera. RAW files can be compressed without losing information, and their compressed size tends to be between a TIFF and a JPEG file. Many photo editing software programs can convert RAW files to TIFF or JPEG files. The advantage of RAW files is that because they retain all of the
information, some aspects such as white balance can be more easily changed in editing than with other files.
Optical zoom works like a telephoto lens. The image quality is the -
Correct Ans: ✅the same as the image is magnified.
Digital zoom - Correct Ans: ✅crops the image and enlarges the cropped image to fill the frame of the camera which can result in a loss of quality.
The white balance is an adjustment that can be made to the -
Correct Ans: ✅color so that whites will appear white in the photograph instead of yellow or blue
Many digital cameras have different modes to give the camera hints about the type of picture you want to take so that it can adjust
accordingly. These modes include - Correct Ans: ✅flash, macro, action, night, portrait, and aperture.
Using the portrait mode can result in a - Correct Ans: ✅less-focused background,
An action or sports mode will use the highest shutter speed possible
to best capture - Correct Ans: ✅movement.
Manual mode allows the photographer to - Correct Ans: ✅control all the adjustments.
Imperfections of the paper transferred to the photograph when positive prints were made and led to experimentation with glass negatives
Joseph Nicephore Niepce - Correct Ans: ✅The first photograph was produced in the 1820's
used a pewter plate and a substance, bitumen of Judea, which hardens when it is exposed to light
The unhardened parts washed away leaving the negative image of the object. Next ink was applied to the image and used like a stamp to make a print of the image.
prototype for modern day photographs.
Louis Daguerre - Correct Ans: ✅partnered with Niepce
made two important discoveries.
First, he found that exposure of silver to iodine vapor before light and then to mercury would create an image.
Second, putting the image in a salt bath "fixes" the image
process was named daguerreotype,
French government bought the rights for the process in 1839.
became a sensation.
the first commercial photography.
The process was expensive, and created one photograph
if more copies were required two cameras were set up side by side.
cost ranging from 50 cents to 10 dollars each.
Frederick Scott Archer - Correct Ans: ✅invented the collodion process
used glass plates covered with a mixture of chemicals before being placed in the camera for the exposure.
Positive prints could be made in unlimited numbers
relatively inexpensive,
allowed photographers to develop a dry-plate technique rather than the wet plates of the collodion process.
darkroom tent did not need to be used with the camera,
process of exposure and negatives was much less cumbersome.
No longer did the photographer need technical knowledge to create the negative
George Eastman - Correct Ans: ✅1884,
created a dry gel on paper, or what we think of as film
eplaced the photographic plates
Kodak camera was introduced to the market with the slogan, "You press the button, we do the rest."
Early Kodak cameras came with film inside, and when an individual had finished the film, the entire camera was sent to Kodak for processing.
camera was then returned with a new roll inside and the negative images
cameras were fairly simple to operate,
Kodak Brownie was introduced in - Correct Ans: ✅1900-
Oskar Barnack - Correct Ans: ✅1913,
built his first prototype of a 35mm camera
The Leica I started production in 1925, and a number of other competitors joined the Leica in the market.
growth in production 35mm cameras remained too expensive for most people until the 1930s.
SLR cameras were also introduced to the public during this time period, with companies like Canon and Nikon entering the market during the 1950s.
The Polaroid, instant cameras that used self-developing film to produce an image in minutes, entered the market in 1948.
The development of instant cameras is generally credited to -
