Unit 57: Photography and Photographic Practice Terminology P1, P2, M1, M2 Photographic Terminology Ashleigh Darlington
Shutter SpeedShutter speed is how long the shutter on the camera lens stays open for as this willchange the amount of light and exposure that will show up on the image that has beentaken this is depending on the length of time that the shutter has been open for.
IsoThis is how sensitive a film is to light depending on what the ISO number is, away to explain this is that the lower the number the lower the sensitivity andthe finer the grain appears in the shots you are taking.
ISOHigh ISO Low ISO
Aperture & Depth of FieldThe way a subject looks in a photograph can sometimes look different fromhow it looked to you as you took the picture this is because when you look at ascene everything in it looks more or less equally sharp but sometimes in thefinished shot only part of the subject appears sharp is called the depth-of-field, and it extends in front of and behind the point that you actually focusedon.

Manual ExposureWhen the camera is inmanual mode thephotographer adjusts thelens aperture and/or theshutter speed to achievethe exposure that theywant.
Automatic ExposureExposure is the amount oflight you allow to hit eitheran object or an area in thephotograph you are taking.A camera in AutomaticExposure automaticallycalculates and adjusts theexposure settings to matchthe subjects mid tone to themid tone of the object youare taking a picture of.
Colour BalanceColour is the global adjustment ofthe intensities of colours, animportant goal of this adjustment isto render specific colours usuallyneutral colours. The general methodis sometimes called gray balance,neutral balance or white balance. The right half shows the photo adjusted to make a gray surface neutral in the same light.
White BalanceThis is the process where youremove any unrealistic colours fromthe picture, this is to ensure thatobjects that appear for examplewhite in person are rendered so thatthey still appear just as white in yourpicture.
CompositionComposition is the arrangement orplacement of visual elements oringredients that are in a photograph.
Rule of thirdsThis applies to the process ofcomposing visual images it is notonly used in photographs it can alsobe used in other things such aspaintings and designs. The guidelinesays that an image should beimagined as being divided into nineequal parts by two equally spacedhorizontal or vertical lines.
Examples of Rule of thirdsThe key interest points don’t alwaysfall exactly on the intersections laidout in the grid although that is a ruleit can be broken.
Analogous coloursThese are colours that are next toeach other on the colour wheel,these colours tend to look goodtogether because they are closelyrelated, these are colours like orangeand yellow.
Complementary ColoursThese are pairs of colours that areclassed as being opposite from eachother. The exact of hue“complementary” to a given huedepends on the model in questionfor example having differentcompliments for different colours.
MacroThis is usually used for when youwant to take pictures of very smallobjects as it is extreme close upphotography so that the subject thathas been photographed appearsgreater in the photograph than it isin real life.
