This camera setting allows you to specify the f-stop, while the camera autoselects the shutter speed
Aperture priority
This camera feature selects the correct focus distance for you, usually based on contrast of image or infrared sensor
Auto Focus
Light-measuring device that calculates exposure based on brightness of entire image
Averaging meter
The Tonal Level of an image where blacks begin to provide important image information, usually measured by using a histogram
black point
To soften an image of part of an image by throwing it out of focus, or by camera motion
Taking a series of photographs of the same subject at different settings to help ensure that one setting will be the correct one
Process used to correct for the differences in the output of a printer r monitor when compared to the original one
This darkroom technique involves exposing part of a print for a longer period, making it darker than it would be with a straight exposure
Movement of the camera, aggravated by slower shutter speeds, causing image blur
Camera shake
A light measuring device that emphasizes the area in the middle of the frame when calculating the correct exposure for an image
Center weighted meter
an image defect, often seen as green or purple fringing around the edges of an object, caused by a lens failing to focus on all colors of a light source at the same pt
Chromatic aberration
Process of changing the amounts of color in an image to produce desired effect
Color correction
Reducing the size of a file by encoding using fewer bits of info to represent the original
Range between lightest and darkest tones in an image
To trim an image or page by adjusting its boundaries
Distance in front of and behind the subject which appears to be in focus
Depth of field
Range that the image capturing surface could be moved while maintaining acceptable focus
Depth of focus
To reduce purity or vividness of a color
Soft, low-contrast lighting
Diffuse lighting
Darkroom term for blocking part of an image as it is exposed, lightening its tones.
Light-sensitive coating on a piece of film, paper, or printing plate.
Amount of light allowed to reach the film or sensor, determined by intensity of the light, amount admitted by the lens, and length of time determined by shutter speed
Automatic setting in automatic camera that provides the optimum combo of shutter speed and f-stop at a given level of illumination.
Exposure program
In photography, lighting used to illuminate shadows
Fill lighting
Distance between the film and the optical center of the lens when the lens is focused on infinity,
Focal length
Camera feature that lets you freeze the auto focus of the lens when the subject you want to capture is in sharp focus, then reframe the photograph without changing focus.
Focus lock
The f-stop is the ratio of what two parts of the camera?
1. effective focal length of the lens
2. diameter of the entrance pupil
Term used to describe the brightest parts of an image containing detail
Point of focus where everything from half that distance to infinity appears to be acceptably sharp.
hyperfocal distance
Light falling on a surface
incident light
Technique used to create new pixels required whenever you resize or change the resolution of an image, based on values of surrounding pixels
Common image file format that supports 24-bit color and reduces file sizes by selectively discarding image data
Lens opening or iris that admits light to the film or sensor
lens aperture
A lens that provides continuous focusing, from infinity to extreme close ups, often to a reproduction ratio of 1:2 or 1:1 (half life size or life size)
macro lens
Exposure metering system using a multi-segment sensor and programming so various parts of a scene can be emphasized when calculating the correct exposure
matrix metering system
Representation of an image in which the tones are reversed: blacks as white, and vice versa.
Condition in which too much light reaches the film or sensor, producing a dense negative or a very bright/light print, slide, or digital image
over exposure
Moving the camera so that the image of a moving object remains in the same relative position in the viewfinder as you take a picture
Smallest element of a screen display that can be assigned a color
Image file format including all the unprocessed info captured by the camera
Number of pixels per inch, used to determine the size of the image when printed
Device that captures an image of a piece of artwork and converts it to a digitized image or bitmap that the comp can handle
Increasing the apparent sharpness of an image by boosting the contrast between adjacent pixels that form an edge
Exposure mode in which you set the shutter speed, while the camera automatically selects the appropriate f-stop
Shutter priority
Type of camera that allows you to see through the camera's lens as you look in the camera's viewfinder
single lens reflex (SLR)
Lens or lens setting that magnifies an image
Condition in which too little light reaches the film or sensor, producing a thin negative, a dark slide, a muddy-looking print, or dark digital image
under exposure
Process for increasing the contrast between adjacent pixels in an image, increasing sharpness, especially around edges
unsharp masking
to enlarge or reduce the size of an image on your monitor/enlarge or reduce size of image using magnification settings of a lens
What are the first 9 full stops starting with f/1.4?
f/1.4, f/2, f/2.8, f/4, f/5.6, f/8, f/11, f/16, f/22
What are the first 7 half stops, starting with f/4
f/4, f/4.8, f/5.6, f/6.7, f/8, f/9.5, f/11
What are the first x 1/3-stops, starting with f/4?
f/4, f/4.5, f/5, f/5.6, f/6.3, f/7.1, f/8, f/9, f/10, f/11
Consider a proper exposure using at f/11 @ 60. Changing the f-stop to f8 would require what shutter speed for an equivalent exposure?
f/8 @ 125
To decrease depth of field, do this to the aperture. What f-stop?
Lower f-stop leads to low depth of field, e.g., f/2.8
To increase depth of field, do this to the aperture. What f-stop?
Higher f-stop leads to higher depth of field, e.g., f/11
