Photographic Technology

The 20th century saw the steady refinement of photography and over the decades it matured dramatically from images on glass plates, using large and heavy brass and mahogany equipment on a sturdy tripod (created by diligent and technically capable camera operators), to lightweight pocketsize cameras that even the most technophobic amateur can use.
 
Photographic technology is a fascinating area of study that any good photographer needs to understand in order to take first-rate photos, and also identify and understand photographic problems when they occur. This course is equally relevant to digital and regular film, and it covers aspects such as image formation, light, lenses, filters, colour and the sensitivity of film or electronic surfaces that record the image.
 

In this course you will learn how to:

• Describe in technical terms how an image forms when a photograph is taken.

• Explain the nature of light and how this relates to the finished photographic product.

• Describe how both the sensitivity of a photo-sensitive surface and its development influence the photographic image.

• Explain how sensitivity relates to the development of a photographic image.

• Explain the composition and manipulation of white and coloured light to create different photographic images.

• Discuss the chemical process that occurs in producing a colour film photograph.

• Explain how a photographic image may be manipulated by using optical filters or other camera attachments, other than lenses.

• Explain how a photographic image can be manipulated by using lenses.
