2.  Perspective refers to the relationship of imaged objects in a photograph. This includes their relative positions and sizes and the space between them. In other words, perspective in the composition of a photograph is the way real three-dimensional objects are pictured in a photograph that has a two-dimensional plane.  http://photoinf.com/General/NAVY/Perspective.htm Perspective

5.   In the visual arts – in particular painting, graphic design, photography and sculpture – composition is the placement or arrangement of visual elements or ingredients in a work of art, as distinct from the subject of a work. It can also be thought of as the organization of the elements of art according to the principles of art.  http://en.wikipedia.org/wiki/Composition_(visual_arts) Photographic composition

8.  Depth of field refers to the range of distance that appears acceptably sharp. It varies depending on camera type, aperture and focusing distance, although print size and viewing distance can also influence our perception of depth of field. This tutorial is designed to give a better intuitive and technical understanding for photography Depth of Field

11.   Depth of focus is a lens optics concept that measures the tolerance of placement of the image plane (the film plane in a camera) in relation to the lens. In a camera, depth of focus indicates the tolerance of the film's displacement within the camera, and is therefore sometimes referred to as "lens-to-film tolerance."  http://en.wikipedia.org/wiki/Depth_of_focus Depth of focus

14.  POV in photography simply means the position from which the camera sees the scene. Are you looking down on the subject? Are you looking up at the subject? How close are you to the subject? Is there anything between you and the subject? Every decision you make about point of view will change how your viewer sees the photo.  http://photography.about.com/library/pointofview/blpointofview.htm Point of veiw

17.  Framing is simply using other objects in your photograph to frame the main subject. This is probably one of the easier composition techniques in photography. Framing brings more depth to the picture and a better focus on what the main subject is.  http://www.photographyblogger.net/framing/ framing

20.   In the printing, graphic design and photography industries, cropping refers to removing unwanted areas from a photographic or illustrated image.   http://en.wikipedia.org/wiki/Cropping_(image) cropping

23.  The use of light in a photograph can be the deciding factor of whether that picture will be spectacular or terrible. When you use your camera to automatically chose aperture and shutter speed, what your camera is actually doing is using the built in light meter and measuring how much light is being reflected to the camera.  http://www.picturecorrect.com/tips/use-of-light-in-photography/ lighting

26.  The appropriate use of color in any photography adds a dynamic element to your images that is very pleasing to the eye. So the correct use of it will allow you to create photographs to be proud of. Bold colors and bright composition in your photos result in images that sell. So use color to your advantage.  http://www.picturecorrect.com/tips/understanding-color-in-photography/ colour
