Chemical and digital techniques can both be used in a number of different and unique ways to capture a photograph that suites your personal style. However, with that said, it is important to remember that there is still a significant difference between the two. In the chemical technique, also referred to as halide technique, it creates an analogue record of an image by using chemical reactions. A digital record on the other hand is an image as a collection of digits. Even though these differences may seem minor, the end result will vary.
Initially, the digital camera was created through the invention of the video camera by Bing Crosby Studios in 1951. Unlike that video camera that transferred data to magnetic tapes. However, the first video camera that used the same device as the digital camera was created in 1970, by Bell Laboratories.
There are a number of different cameras in the market that promise great results. However, even though all cameras might give you a satisfactory end result, they all work in their own way, capturing imagoes in different styles and ways. With that in mind, it is important to understand just how a digital camera works so you can choose the best camera that suite your personality, style and taste. Photographers need to pick a camera that they feel comfortable with. Its also important to read the cameras manual and take test shots before capturing an event, this will help ensure that you do feel confident and will not be fighting with the camera the whole night trying to figure out which button does what, ultimately degrading the quality of you performance and photographs.
An image is captured in a digital camera when the light falls onto a variety of light-sensitive sensors, contained in a charge coupled device (CCD). The original and first CCD was designed by Willard Boyel and George Smith. The colors of the charges are red, green and blue. The sensors then convert the light into a digital form that is capable of recording color and intensity. The more sensors a CCD contains, the more pixels are used to form the image. The number of sensors on a CCD is simply measured in megapixels. For a professional, the minimum one uses is a single-lens reflex (SLR) with 4 megapixels. The benefits of using a digital camera verse a film camera, is that a digital camera stores its images on a memory card. The number of images that a card can store depends on the size of the card, the amount of detail on each individual image and the amount of exposure you select. Digital cameras also allow you to view you pictures before printing them and make any editing that is needed.
Now, let’s look at a few models of digital cameras to see how they all work in their own unique ways.
First we have the CANON EOS D3O, it’s a more upscale and expensive model; however, it lacks the rugged build of expensive models but is capable of capturing sharp images. The CANON EOS 1D is capable of withstanding tough handling however; its downside however is its 4 megapixel chip does not capture detail. Canon has been known for its long chain of excellence and good quality reputation. With the release of every new canon camera, new innovation has been made, keeping Canon a strong competitor. Kodak is also another strong competitor who unfortunately began to take a turn for the bad in 2003 when they released Kodak 14n. however like all great companies Kodak made a huge hit when it introduced Kodak DCS pro Back 645. Leaf is one of the cameras that can literally cost you an arm and a leg. Selling at about $30,000, the leaf is one of a kind. With a chip that can hold up to 645 frames, space will never again be a concern. This chip also gives shadows at least a half stop more than other cameras.
