Amazon Rapids Fun stories for kids on the go. To narrow down your search, try to determine which of these types will best fit your needs. When you know how it all works, then you know how to make it work. About This Class Do all the settings, controls and buttons on your camera have you taking pictures on automatic all the time?
The increasingly complex digital cameras on the market today offer a bewildering variety of ways to control their operation, and understanding how turning dials and flipping switches affects the images you end up with can make your head spin. To get the most out of your photography and to best use your camera as a tool to create beautiful imagery, you really need to go back to the beginning and learn all about the basics. A strong grounding in the fundamentals in photography is essential to make this possible.
When you know how it all works, then you know how to make it work. You will know how to set your exposure to capture the detail you want. You will know how to control light to show people what you want them to see. You will know how to react to unexpected situations and fleeting opportunities. As with many things, there are different ways of looking at the same topic.
I hope that by offering another perspective, I will be able to complement the existing DPS articles. I will link to relevant articles whenever it would be helpful. While traditional photography uses photographic media that reacts when exposed to light creating a picture , digital photography uses a photosensitive plate that translates the wavelength of the light that strikes it into 1's or 0's, hence the name digital.
Both forms of photography, however, use optical lenses to focus light onto the respective medium.
The sequence of 1's and 0's that make up the photograph is called a file. The file, and effectively the photograph, can be reproduced perfectly and also transferred over the internet or other forms of digital communication without loss of quality. The disadvantages of digital photography are directly related to limits in technology. To have a high quality image, you have to have an extremely large amount of 1's and 0's.
The limiting factor is the plate that translates the light into digits. In first generation digital technology, the plates were not very good at digitizing the light, and so digital photographs taken with these plates look fuzzy and "squarey.
The resolution of an image taken by traditional means is limited by the film it is taken on and the lens that focuses the light. Some film is better than others, and some lenses are better than others. While mild enlarging and cropping of a traditional photograph can be done in the darkroom without much loss of resolution, the sharpness and clarity of the image decreases as the image is enlarged and less of the surface area of the film is being used to create the photographic print.
This does not refer to the effects of "zooming in" with a tele-photo lens, which vary greatly depending on the lens and can be just as sharp as any other kind of photo. Because the whole surface of the film is still being used when one uses a tele-photo lens the quality of the image will be equal to an image captured on the same film with any other lens of equal quality.
The resolution of a digital image is limited to the quality of the plate and to the quality of the lens in the same way that a traditional photograph is limited by the film and the lens. A higher quality plate records more information measured in pixels or Megapixels , in the same way that a lower ISO film is able to record a higher resolution image.
In the same way that a traditional photograph loses sharpness and clarity when it is enlarged, digital images that are later cropped either to alter the composition or "zoom in" decrease in quality as the resolution decreases and noise becomes more apparent.
Lower-quality digital images are notorious, however, for losing quality much more rapidly than a traditional photograph. One advantage that digital photography has over traditional is that digital photographs can be stored on a computer or a small data storage device.
