Chapter 5: Techniques of Photographic Interpretations – Geography Form Five New
Photographs are the true image pictures showing truly appearance of the earth’s surface objects on the flat bodies of special pieces of paper taken with the use of a camera and chemically printed. Or
Photographs are the pictorial representations of the remote sensed data recorded on film in a camera then chemically printed on special pieces of paper.
With respect to the definition given, photography is produced as the image of the object captured and recorded with a camera on a light sensitive film. The film by then is developed in a developer machine to remove darkness in it to develop brightness of object’s image.
The image in the film by then printed on a special paper using chemicals to develop clear true image pictures. The camera recording the images of objectives can be mounted on the ground or aerial platform.
A person who takes photography with the use of a camera is called photographer; and the art of producing these pictures is known as photography.
Photographers have potential significance in geographical studies in a number of ways. For instance; they are used to assess the geographical facts of respective areas.
Alternatively used to make storage (recording) of the geographical details of pieces. It has to bear in mind that, land details change with time, but a photography once produced remains unchanged.
Some of the geographical details that can be assessed from photographs include; relief, land use, drainage features, settlement and vegetation.
Qn. All photographs are images but not all images are photographs
The following are clear points explaining why all photographs are images, but not all images are photographs:
1. A photograph is a type of image created by capturing light on a photosensitive surface (film or digital sensor).
2. An image is a broader term that includes photographs, paintings, drawings, diagrams, computer graphics, and more.
3. Photographs are produced through cameras, while images can be created by hand, digitally, or mechanically.
4. Photographs rely on optical devices and light, whereas images may exist without any optical process (e.g., sketches).
5. Photographs usually depict real-world scenes, while images can represent abstract ideas, symbols, or imaginary concepts.
6. Photography requires specific technology (camera, lens, sensor), but images can be made with simple tools like pencils or software.
7. Photographs often aim to capture reality, while images may be stylized, manipulated, or entirely fictional.
8. Photographs show actual object, people or scenes as they exist but images represent ideas, imaginations and symbols.
9. A photograph requires natural or artificial light to be recorded while image can exist without camera or light, it may be purely digital or hand-made.
10. Photograph restricted by photographer’s angle, lens and environment while an image has unlimited creative freedom, not bound by physical reality (can be modified by producer)
