- EDU3105 T7-BASIC PHOTOGRAPHY 1 TOPIC 7 BASIC PHOTOGRAPHY SYNOPSIS This topic introduces the basic photography where students will be able to find some shooting techniques that have diversified. By learning the basics of photography students were also able to identify parts of a camera. With the latest digital era students will fill more challenging for the use of photography in education. TITLE FRAME 7.1 The history of photography 7.2 Basic parts and functions of the camera 7.3 Types and camera accessories 7.4 Types of films 7.5 Techniques of shooting 7.6 Composition 7.7 Digital photography 7.1 Development History of Photography History has shown the existence of photography since the late 19th century where the first photo was made in 1826 for 8 hours. The term Photography derived from the word photography that was originated from the greek word meaning light (phos) and write (graphien). Louis Jacques Mande Daquerre was the first to introduce photography and he is also known as the father of the world of photography (1837). Obscura camera is the first camera that used to draw then photographing. Kodak cameras (Kodak Eastmant) was first found by Snapshooter 1888 in America. Edward Muybridge was the the person who contribute photography into the world of film. Flash or the flash was first discovered by Harold E.Edgerton in 1938. Photographing dead things called still life. The discovery of negative film by John Hendri Fox Talbot made for 40 seconds under the scorching sun.
EDU3105 T7-BASIC PHOTOGRAPHY 2 Basic Photography Try to think. How important is photography in the process of producing materials for teaching and learning? Basically all cameras are the same. It is a box with a hole that controls light on one end and a space to put the film on the other end. These openings allow light into the box and shone to the film that was already inserted to form an image. The more complex the building / structure of a camera, the more complete the mechanism. The completeness and efficiency of this mechanism will also affect the results. To produce a decent result, a camera must have: i. A tool that allows users to view the camera direct to the target. This section is called the view finfer. It allows users to view the target. ii. An opening called the aperture that allows light into the camera. iii. A lens which collect light and project the image onto the film. iv. A closing and opening device of the lens that can be controlled is known as shutter. v. A button called shutter release which when pressed will open the shutter curtain briefly enough to let light into the camera and create an image on the film. vi.Film with light sensitive surface facing the lens.. vii. Tools to roll film. viii. A focusing mechanism to change the position of the lens backwards and forwards so that it can produce sharp image. EDU3105 T7-BASIC PHOTOGRAPHY 3 7.2 Parts of Camera A camera consists of several parts and components Diagram 1: Basic Parts of Camera Source (Book): Teknologi dalam Pengajaran dan Pembelajaran 7.2.1 Lens The lens is used to form a clear image on the surface of the film in the camera. The main feature of a camera is the focus distance. Lens with different focal length can form different image on different film size. The distance of a focal length is measured in mm unit. Normal focal distance will form an image of a normal saiz no matter what types of camera used. Normal focal distance is different depending on the film saiz used as follow: EDU3105 T7-BASIC PHOTOGRAPHY 4 Film size Normal focal length 110 25 mm 126/127 45 mm 35 50 mm 120 75 mm Types of Lens i. Wide Angle Lens Size 6 mm - 45 mm. Used for shooting scenery or narrow space. Distant view of the area. ii. Standard or Normal Lens Size 43 mm 50 mm. Most used. View size is almost the same as seen by normal human eye. iii. Telefoto Lens 85 mm 120 mm Used for shooting portrait picture 135 mm 200 mm Suitable for shooting sports event 300 mm 600 mm suitable for moving target, nature, wild life iv. Zoom Lens Zoom lens is a lens that contains a combination of lenses in one unit of either normal angle to wide or wide angle to normal. Zoom lens is normally used in situation where subjects or targets always changes its position. In this situation a photographer have no time to change to different lens. 28 mm - 50 mm wide to normal angle 50 mm 100 mm normal to moderate angle 70 mm 200 mm normal to distant angle 135 mm 300 mm moderate to distant angle EDU3105 T7-BASIC PHOTOGRAPHY 5 Diagram 2 : Zoom Lens Sumber : Canon Marketing Malaysia 7.2.2 Shutter The shutter is a curtain that covers the surface of the film from light. The Shutter curtain will only be open for a certain period of time so that the film is exposed to light sufficiently to get a good photograph. Shutter curtain will only be open for a certain period of time just enough to get a good photograph. The index speed of a shutter are shown with these numbers: B, 1, 2, 4, 6, 15, 30, 60, 125, 250, 500, 1000 and 2000. These numbers indicate a fraction of a second. Thus 1 means one of a second, 2 means half of a second, 4 means quarter of a second and so on. These fractions show that the bigger the number the faster the speed of the shutter curtain opens and closes. They also mean that the shotter time the shutter curtain opens the shotter time the film exposed to the light and vice versa. Thus a shutter is a mechanism that controls the time where light enters the lens. Diagram 3 : Shutter Release /Shutter Speed EDU3105 T7-BASIC PHOTOGRAPHY 6 7.2.3 Aperture Aperture is an opening in the lens. The size of the opening can be adjusted through the aperture ring. Through this adjustment the aperture size can be modify (big or small). The size of the aperture will determain the amount of light passes through the lens. Thus the function of the aperture is to control the amount of light entering the lens . Too little light will under exposed the film and too much will over exposed it. In this case a photographer should know how to control the amount of light. He has to regulate the aperture ring and choose an appropriate aperture scale. The size of an aperture is measured with f/stop number. Thus you can see the number such as 2.8/3.8, 4, 5.6, 8, 11, 16, 22, 32 on the aperture ring. These numbers indicate that the smaller the number the bigger the size of the aperture and the bigger the number the smaller the aperture (see the diagram below). Nevertheless these number scales depend on the types of lenses used. Expansive lens usually has wide range of aperture scale of f/ number.

This process is done by rotating the lens focusing ring while the photographer view the subject in the viewfinder. Doubled or blured image shows that the object is out of focus. Clear image shows that the object is in focus. Diagram 6 : Focusing ring and distance scale 7.3 Types of cameras There are several types of cameras available in the market. Among them is a disk camera, instant camera, cartridge camera, reflects camera and large format cameras. 7.3.1 Fixed Focus Camera This type of camera has no focusing mechanism. There was only a view finder a little further from the lens position. Most of these cameras have a fixed aperture and cannot be modified. But there's also a type with simple aperture adjustment marked with the symbols as follows: EDU3105 T7-BASIC PHOTOGRAPHY 8 Diagram 7 : Fixed Focus Camera Exercise 7.1 You are required to find information about the types of cameras and the basic parts of the camera. Then discuss with your partner the types of cameras available in the market today. 7.3.2 Range finder camera This camera has a focusing mechanism on the lens and its shape is similar to a fixed focal camera. The mechanism allows the photographer to adjust the lens (to focus) in order to get clear and sharp images. To take pictures in bright sunlight and significant shadows. To take pictures in bright light but with vague shadows. To take pictures in cloudy day with little shadows . EDU3105 T7-BASIC PHOTOGRAPHY 9 7.3.3 Single Lens Reflects (SLR) SLR cameras do not have a view finder in the front. It only has a view finder at the rear. The image seen in the view finder is actually the image that reflected (with the help of pentarisme) to the film through the lens. This camera is equipped with an interchangeable lens. Lens can be changed even if the camera is loaded with film without exposing it. It can also use a telephoto lens, wide angle lens, micro lens and other attachments.

This camera is quite large and heavy. It is found in SLR type and TLR (Twin Lens Reflex). TLR type has two identical lenses mounted on top of each other. The top lens is used as the viewfinder while the objective lens attached underneath.

Due to the large camera design, the camera of this type are often used by professional photographers in the studio to get the maximum quality pictures. Rajah 11 : Large format camera 7.3.6 Instant camera This type of camera can produce photos and slides in a short time span, between one to two minutes. The film surface is coated with a special chemical that can process the image into positive within a few seconds. EDU3105 T7-BASIC PHOTOGRAPHY 11 Diagram 12 : Insta
