1 Digital Photography Vocabulary









10 Digital Photography A type of photography that involves using a digital image.

11 Digital Image Any picture or graphic in digital form.

12 How a digital camera works

13 Aperture Is the size of the opening lens when a picture is taken When you hit the shutter release button of your camera a hole opens up that allows your cameras image sensor to catch a glimpse of the scene you are wanting to capture. The aperture that you set impacts the size of that hole. The larger the hole the more light that gets in the smaller the hole the less light

14 Large aperture = small f number Small aperture = larger f number

15 Aperture controls the depth of field Depth of Field PowerPoint

16 Shutter Speed shutter speed is the amount of time that the shutter is open shutter speed is the length of time that your image sensor sees the scene you are attempting to capture Controlled by shutter button

17 Shutter Speed is measured in seconds 1/1000 is much faster than 1/30 In most cases you are probably be using shutter speeds of 1/60th of a second or faster Camera Shake- results a blurring picture- slow shutter speed- have to use a tripod




21 Light writing

22 ISO Carried over from film “old days”- buy film rated 00, 200 or 400, maybe even 800 or 1600 number refers to the films sensitivity to light

23 ISO Lower number 100 or 200- used for sunny days where there is a lot of light Higher number 400 or 800 used for times when there is not a lot of light

24 So what does sensitivity mean? low sensitivity- film has to be exposed to light for a longer period of time than a film with a high sensitivity in order to properly expose the image. Try to use lowest sensitivity- pictures of are better quality

25 If you used an ISO of 100 indoors Chances are- you would need a flash or photo would come out dark Film ’ s sensitivity is so low that the shutter would need to be open for a long time to let enough light in.


27 Mega pixels Are the basic way to measure how sharp your pictures can be The smallest area of a picture with a distinctive color, kind of like a “molecule” of a picture A Pixel (a word derived from PIX" (short for "pictures")



30 Pixilated

31 Noise Looks grainy caused by (interference when you try to make the film/sensor more sensitive when it has little light to work with)


33 Lens Sharpness quality of an image indicating clear or distinct detail: associated with resolution and contrast

34 Zoom a term that is used to get a closer view of your subject without actually moving closer to it.

35 Optical Zoom a true close up which uses the whole cameras view to make the image. You get full resolution, not just a cropped piece of the view.

36 Digital Zoom A mere crop of the central part of the whole image, creating a close up of the image from the central pixels only.


38 Resolution can be defined as the number of pixels that, constellated together, form an image or a photograph Ppi- Pixels per inch

39 Memory Card An electronic chip inside a slim plastic casing. It stores information such as image data in newer cameras.

40 Default Settings that a camera or digital software offers in the absence of other instructions. They come preset with the item. –PSD - Symbol used to identify Photoshop documents. –Scanner a machine that is used to make a digital copy of your original photographs, or negatives.

41 PDF Portable Document Format, created by Adobe. Allows you to view visually rich content on different platforms and display devices Aperture, Shutter Speed and ISO Video

42 Cropping the process of selecting and removing a portion of an image to create focus or strengthen its composition.

43 Rule of Thirds PowerPoint video

44 Exposure the total amount of light allowed to fall on the sensor during the taking of a photograph

45 Menu Lists a number of options offered by the camera.

46 Modes Macro Mode- lets you move your closer into your subject to take a close up picture. Its great for shooting flowers, insects or other small objects.


48 Portrait Mode When you switch to portrait mode your camera will automatically select a large aperture (small number) which helps to keep your background out of focus (sets a narrow depth of field ensuring your subject is the only thing in focus


50 Landscape Mode sets the camera up with a small aperture (large number) to make sure as much of the scene you are photographing will be in focus as possible (large depth of field). It therefore ideal for capturing shots of wide scenes, particularly those with points of interest at different distances from the camera.

51 Sport Mode Photographing moving objects. It is ideal for photographing any moving objects including people playing sports, pets, cars, wildlife etc.

52 Nights Mode Colorful interesting shots low shutter -is for shooting in low light situations and sets your camera to use a longer shutter speed to help capture details of the background but it also fires off a flash to illuminate the foreground

53 Over exposed process of exposing film to too much light Lose details and forms


55 10:30

56 Perspective One’s Point of view A unique perspective makes for a very interesting photograph










66 Silhouette a two-dimensional representation of the outline of an object Light source from behind object Usually solid black
