The beginning is a list of things to know about photography. The college taught me undergraduate photography classes for years each semester, and I submitted this list of terms. Yes, there are manuals and training books, but through them to find the basic minimum to start the time, as listed below. Print it out, carry it in your photo bag and refer to it as needed. If you are interested in knowing more about the term, then you can try it. In this way it is understood that good is the principle.
ambient – ambient lighting is available in or around light
aperture – the amount of light let in through the lens (per lens aperture) see f-stop
ASA – film speed rating similar to the IOS rating
bracket – let’s go over and then under the exposure from the indicated camera settings. This technique offers several different exposures from which to choose the best negative to print.
burn in – to darken a specific area of a note, and to print it with additional exposure
besides – the difference between good light and dark. An image that is only pure black and white, with no shades of gray, is said to have high contrast. Images with many shades of gray and no black or white are low
density – the amount (or thickness) of silver in the film or paper. More negatives were exposed to dense (thick) silver. When the maximum density is reached the negative or figure is as black as possible. This maximum density is called D-MAX.
depth of field – the distance between the closest and outermost points that are in acceptably sharp focus. The depth of field is altered by 1. the aperture size 2. the length of the lens 3. the distance to the subject
hits – to reduce the footprint of the print on the exposure side of the Typography
emulsion – a sensitive coating applied to photographic film or paper. It consists of silver crystals and other chemicals suspended in gelatin
fill light – a lighting source that illuminates the darkness cast by the main light and thereby reduces the contrast in the photograph
f-stop – also refers to a number. A number indicating the size of the lens opening. It is determined by dividing the focal length of the lens by the diameter of the aperture, measured in millimeters.
grains – negating silver flakes that give the image a “sandy” or “dotted” appearance. Films with a lower ISO number will have less clumping and therefore finer grain.
ISO – (international standards organization) numerical rating that describes the sensitivity of movement to light. The ISO rating doubles as the motion sensitivity doubles. A rating that combines ASA (once a standard in the US) and DIN (a European standard) would be an example of ISO 100/20*
panning – to follow the movement of a moving object with the camera, this will make the object look sharp and the ball dull.
reciprocal – reciprocity law – relationship between exposure length and aperture size. When equivalent developments are required, an increase in one is offset by a decrease in the other. For example, a doubling of the aperture size will be exactly equaled by an intermediate exposure time. The law of reciprocity fails in the shortest or longest expositions.
stops – as a smaller aperture lens
