Check your basic knowledge of some common photography terms and Techniques.
Answers are at the bottom of this post.
An image file that contains minimally processed data from the image sensor of either a digital camera, image scanner, or motion picture film scanner is called…
a. RAW file
b. DNG file
The technique of taking the same photo more than once using different settings for different exposures is called:
a. Double exposure
b. Exposure bracketing
What does HDR technique in imaging stand for?
a. High distance range
b. High dynamic range
The level of a sensitivity of a camera to available light is called…
a. Shutter speed
The hole within a lens, through which light travels into the camera body is known as:
The text information pertaining to an image file that is embedded into the file or contained in a separate file that is associated with it is called…
a. Exif metadata
b. History of editing
The family of techniques that reduce blurring associated with the motion of a camera or other imaging device during exposure is called…
a. Image Balance
b. Image Stabilisation
What type of adjustments should be used for removing color casts, so that objects which appear white in person are rendered white in your photo?
a. White Balance
b. Color Correction
The length of time when the film or digital sensor inside the camera is exposed to light, also when a camera’s shutter is open when taking a photograph is know as:
a. Shutter speed
b. Shutter range
The effect associated with wide-angle lenses and, in particular, zoom wide-angles is called…
a. Lens Distortion
b. Barrel Distortion
1/10 answer: Raw files are named so because they are not yet processed and therefore are not ready to be printed or edited with a bitmap graphics editor.
2/10 answer: Exposure bracketing is a simple technique professional photographers use to ensure they properly expose their pictures, especially in challenging lighting situations.
3/10 answer: High dynamic range (HDR), as its name implies, is a method that aims to add more “dynamic range” to photographs, where dynamic range is the ratio of light to dark in a photograph. Instead of just taking one photo, HDR uses three photos, taken at different exposures.
4/10 answer: In Digital Photography ISO measures the sensitivity of the image sensor. The same principles apply as in film photography – the lower the number the less sensitive your camera is to light and the finer the grain.
5/10 answer: In optics, an aperture is a hole or an opening through which light travels. It determines how collimated the admitted rays are, which is of great importance for the appearance at the image plane.
6/10 answer: Photo Exif metadata contains the additional information about the photograph parameters that is stored in the image file, and can be understood by other software, hardware, regardless of the format.
7/10 answer: Generally, image stabilization compensates for pan and tilt (angular movement, equivalent to yaw and pitch) of the imaging device, though electronic image stabilization can also compensate for rotation.
8/10 answer: The White Balance setting you choose will change the colour balance in your picture, making the whole image warmer or cooler depending on the sort of light you’re shooting in.
9/10 answer: In photography and digital photography the shutter speed is the unit of measurement which determines how long shutter remains open as the picture is taken.
10/10 answer: The Barrel Distortion effect causes the image to spherize, which means that the edges of the photo look curved and bowed to the human eye.
