Why Do We Question Truth Of Digital Photography when the real world in which we live is an analog world.  Light and sound come to us as continuous analog waves that our senses interpret.  Unforntunatel it is very difficult to invent a technology that can accurately record a continuous analog wave.

 

Storing a series of numbers on the other hand is much simpler.  They can be recorded on a chip.  therefore, by representing something in the real world as a series of numbers, then you can very easily store those numbers using your chosen recording medium.  This is called the digitizing process.  To sum it up, two of the factors that determine the quality of a digitizing process are the resolution (the size and number of your individual pixels and dynamic range (how big a range of color choices you have for each pixel).

Many other factors affect quality of a digitized image from optical quality to compression.  In essence, digital cameras face many problems and these problems may show up in your image.

In summary, there are so many processes that affect the outcome of a digital photograph that what the naked eye sees is not necessarily interpolated the same as when the digital camera snaps the picture.  As Jon Szarkowki said “our faith in the truth of a photograph rests on our belief that the lens is impartial and will draw the subject as it is, neither nobler nor meaner”.  This faith may be naive and illusory (for though the lens draws the subject, the photographer defines it”.
