Im a fan of the satirical and cynical definitions of Ambrose Bierce, first written as a daily newspaper column and later collected in The Devils Dictionary. (It was originally called the Cynics Word Book, but so many politicians of the day called Bierce a Devil that he felt the new title more appropriate.)
Unfortunately, very few of Mr. Bierces definitions apply to photography. Seeing a need that should be filled, I immediately began working on a Devils Dictionary of Photographic terms. Hopefully, some of you will join in and help to expand this desperately needed work.
The Cynics Photography Dictionary
Aberration Something that is wrong with the lens by design, as opposed to something wrong with the lens by accident of assembly or use.
Action photography The use of very large, expensive lenses to make rapidly moving objects appear immobile.
Aperture The opening of a lens, identified by a number that gets larger as it gets smaller.
Bokeh the look of the picture in the parts where you can’t tell what youre looking at.
Build Quality How heavy the metal barrel, on the outside of all the important parts of the lens, is. For example, any lens weighing more than 2 pounds has great build quality.
Corner The edges of an image, generally known for lower image quality. They begin at the 4 points furthest from the center of the image and, depending upon the equipment and photographer, comprises between 20% and 100% of the image.
Decentered An image showing very poor quality. This is usually assumed to be caused by the equipment mounted to the front of the camera, but is often actually caused by what is behind the camera. See also, Sample Variation
Depth of Field The part of an image that is in best focus, traditionally placed just in front of, or just behind, the subject See also, Autofocus.
Genre Broad categories of photography such as landscape, action, glamour, wildlife, and portrait, all of which taken together are less common than the most popular genre, the selfie.
Glamour A type of photography practiced by many and mastered by few, with the purpose of creating images of creatures not found in nature.
Image Stabilization a technologic triumph consisting of lenses, magnets, position sensors, springs, and electric motors that is nearly as effective as 3 sticks of wood attached to a base plate. See also, Tripod.
In Spec Slang term meaning both we can’t make it any better before we go on break and you probably can’t tell the difference anyway.
Lens coating thin layers of of substances applied to clear glass that makes it clearer. In the 1600s people were burned at the stake for claiming things like this.
Minimum Focal Distance How close an object may be to the front of the lens, yet still be in focus. Historically of importance for macro photography, but today used to make certain arms-length Selfies are in focus.
Phase Detection Autofocus a method to approximately put the plane of focus somewhere near an object approximately selected by a point in the viewfinder that approximates the location of a dedicated sensor in the camera which is approximately calibrated to the cameras image sensor. See also, Depth of Field.
Render from the German Render. Something an expensive lens is said to do, especially when it doesn’t do anything else exceptionally well.
Sensor The device that actually takes an image. Its most important attribute is the number of megapixels unless yours has fewer, in which case dynamic range, high ISO performance, microlens effectiveness, color accuracy, and other characteristics are more notable.
Sharpness The amount of fine detail visible in an image before it is compressed to 1/10th its original size to post online.
Silence The response of many wives and at least one camera company when an obvious problem arises.
Sample Variation The difference between this lens and that lens, even though both of them are the same lens.
Stop Down To move the f-number up.
Technique The methods that let someone else make pictures I couldn’t afford to buy, using equipment that I would throw away, and vice versa.
Tripod A stabilizing device with three legs that everyone agrees would improve the sharpness of images taken by others. See also, Image Stabilization.
Vignette A technique used by lens designers to make the image very dark in the places where the lens is very bad, based on the principle that if things are dark enough you won’t notice how bad they are.
Weather resistant A term that consumers falsely define as weather proof and camera companies accurately define as the warranty doesn’t cover water damage.
Wedding Photography, n. A complex form of photography that consists of first of making hysterical people appear calm and joyous, and later making sloppy-drunk people appear pleasantly tipsy. The purpose is to create a beautiful album of images that statistically has a 54% chance of being ripped into little pieces within 5 years.
Of course, this list of definitions is incomplete so please add ones Ive missed as comments. If things go as they usually do with my blog, the comments will end up being far more amusing than the original post.
