Digital Photography en Photography has changed the way people record and remember images, events, and scientific information. Photography, which started in the mid 1800's, has continued to evolve over the last two centuries of scientific discovery. The development of flexible film in the late 1800s, color photography in the mid 1900s, and automatic cameras in the late 1900's changed the way photographs are taken and presented. The most recent addition of digital photography has also changed the way people collect, store, modify, disseminate and display images. Digital photography started with the advent of the first commercial digital cameras for consumers and professionals in the early 1990's, along with the first systems for digitizing film images.
Equivalence Let's begin by considering a couple of experiments you can do at home. Take a photo of a scene at, say, 35mm f/5.6 1/200 ISO 3200 and 70mm f/5.6 1/200 ISO 3200. Crop the 35mm photo to the same framing as the 70mm photo, and display both photos at the same size. These photos have the same exposure, and are taken on a camera using the same sensor, thus the same efficiency and pixel size. Which photo is more noisy and why? Here's another experiment. Depth of Field - Digital Photography Tutorial - Focal Length - Opinion The perspective-flattening of long lenses can also be used in other circumstances, because they also have the effect of reducing depth of field. You can use this to isolate a subject against its background by blurring it out, as in the shot below. Compare this with the same shot but taken with a wide angle lens from a much closer range. The relative size of the statue is the same in both shots, but due to the increased depth of field in the wide angle shot, the background, although apparently more distant, is much sharper. Because of this reduced depth of field, careful focusing with a long telephoto lens can pick out individual subjects amidst cluttered surroundings, such as a single person in a crowd. Note also that the perspective-compression effect makes the street look a lot busier than it really is.
