These days digital technology is can be found everywhere due to its affordability. We are all exposed to these digital movies, photographs, and music that have made their way into new forms and designs of digital formats. One of these new formats is digital photography, which is becoming more common and popular all the time with photographers of all experience levels.
Digital photography is popular for many reasons simply because it is so versatile for taking all types of pictures. Digital photographs can be sent to family and friends through e-mail, they can be displayed on web pages, they can be copied to CDs, and they can be easily stored on your home computer. Digital photographs can also be modified to slide shows and can then be viewed on your computer monitor or your television. The other advantage about digital photographs is that you can print them in non-traditional forms that you can then use them to create greeting cards and personalized calendars as well as copy them on t-shirts and mugs.
Perhaps the biggest advantage for most photographers is that digital photography means you don’t have to process the pictures like traditional photos. You can avoid that visit to the photo shop to develop your pictures since you can easily view your pictures on your home computer as well as on the digital camera itself. Digital photography eliminates the developing process, which can save you a lot of money, and doesn't use harmful chemicals that harm the environment.
Still another advantage to digital photography is the ease with which photos can be edited and altered. You can modify digital images in a variety of ways through the use of many types of computer software. Some of the alterations you can make include cropping, enhancing and changing colors, adjusting the contrast of the picture, eliminating imperfections, and combining two or more photo images to create interesting and new designs. All of these modifications can be made in just a few minutes with just a few mouse clicks and key strokes.
The best way to take advantage of digital photography is to use a digital camera. And if you are a beginner to digital photography what better way to get started than by buying a used digital camera. However, you can also use a classic camera and then modify the picture negatives into digital photographic format. Converting your classic picture negatives will give you a good idea of whether or not you want to invest in a digital camera. This way you can determine if you want to learn more about digital photography without having to spend a lot of money on new camera equipment. Most photo developing stores will offer the service of converting your classic film negatives into digital format.
Classic cameras are much more limiting than digital cameras. A digital camera provides you with a viewing screen that you can use both as a picture finder and as a view finder. This digital camera feature lets you look instantly at the picture you have just shot. If you aren’t happy with the picture you can delete it and start all over again. A digital camera also allows you to crop some sections of the picture before you save it into the memory of the camera. Some digital cameras, both older and newer models, can be used as video recorders so that you can take video footage with sound.
If you think that all of the above comes at a heavy cost you will change your mind when you look at the reasonable cost of buying a used digital camera. Digital photography is very affordable for most buyers when you consider the technology that comes along with it, allowing you to take great pictures. The money that you will save buying a used digital camera can be quite considerable. And don’t forget the money you will save by not having to develop all those negative from your classic camera. Digital photography is both affordable and practical, as well as a great way to advance your interest in photography.

Classic Photography or Digital Photography?
Although digital photography is a new and innovative way to take photos it is still founded on traditional photography and incorporates many of the same ideas. Both digital and traditional photography need a lens with which to focus the light as well as a shutter that lets the light into the camera. The big difference between traditional and digital photography is how the camera captures the image.
In traditional photography a film is used which needs to be developed inside of a darkroom with the use of chemicals. This development process results in a "negative" which you will then to print so that you can see the picture. Digital photography uses what is called an electronic sensor. It's this electronic sensor that catches the image of the picture. Millions of pixels make up the sensor, which then convert the light into a number. Instead of waiting for the photo to be developed a digital photo can be looked at almost immediately in the viewfinder of the camera.
Digital photographs use the number of pixels to determine the quality of the picture. Pixel count is often referred to as "resolution" and is measured in dimensions, such as 800x600. This is also known as the number of pixels per inch. A typical resolution for a computer monitor is 800x600. What this means is that the computer screen can display 800 pixels from one side to the other side and 600 pixels from the top of the display to the bottom. The total number of pixels would be 480,000. Digital photography uses resolutions that are higher than the computer monitor, often resulting in millions of pixels, or megapixels. If a digital camera has a resolution of 2048x1536 it has a total of 3.1 megapixels.
As previously mentioned, numbers represent the pixels. These numbers then determine the scale of colors that can be created. As an example, pictures that are black and white can be represented by megapixels that are only 8 bits long. As with binary arithmetic, an 8 bit number can then represent any decimal number from 0 to 256. This means that black and white pictures can have as many as 255 gray shades as well as black (0) and can also have white shades (256).
Larger numbers represent colors. For example, 16 bits per pixel can have a color scale of 65,536 different color shades while 24 bits per pixel can have over 16 million different types of colors. These days most digital cameras make use of 24 bits per pixel; however some professional cameras can have a color resolution that reaches 48 bits per pixel to create over 280 billion color shades.
The quality of a digital camera is affected by a few factors. Most times pixel resolution is considered to be one of the most important factors. You will want to choose the right pixel resolution for the size of pictures that you want to print. Remember that although the number of pixels in the photo won't change those images with bigger dimensions will have less pixels per inch. This will result in less detail in the picture as the size increases.
Photography labs will print photos that are 300 pixels per inch. This standard measure will let you calculate just how many megapixels your digital camera should come with. The largest print you can get from a two megapixel camera (that has 300 pixels per inch) is a 5.8"x3.8" picture. This is smaller than the standard 4"x6" picture. A digital camera that has four megapixels will be able to print photos up to a size of 8.2"x5.4" at about 300 pixels per inch.
You still have the ability to print larger photos. Keep in mind that photos which are printed at 200 pixels per inch will be less clear, however these photos will still be useable for many purposes. With this type of resolution you can get photo prints up to 8.7"x5.8" with a two megapixel camera. And with a four megapixel camera you'll be able to get pictures up to 12.2"x8.2".

brief history of digital cameras
There is a saying that a picture is worth a thousand words. This is very true but to get this thousand word picture you need really high quality cameras or digital cameras. While many of us take for granted the presence of digital cameras and the many marvelous things that they can do we have forgotten the history of digital photography.
This history of digital photography is not that long but the events that took place have changed the way that we take our photographs.
In 1969 October 17th George Smith and Willard Boyle invented the charge coupled device or the CCD as we know it. This device was originally made for use in computers as a semi-conductor memory. These inventors of the CCD were also thinking about ways to incorporate their device into video phones.
With all of their plans and sketches finalized Smith and Boyle finally built the CCD into the world’s first CCD camera. This changed the history of digital photography altogether.
The camera that was built by them was a solid state video camera. During 1975 the CCD camera with its image sharp pictures was shown on television for the first time. The image that was shown was clear enough to be seen by the viewers of television.
In the history of digital photography the first prototype of the digital camera was created by Sony in1981. This digital camera was called Mavica which meant Magnetic Video Camera. The Sony Mavica was essentially a video camera that was used to capture video freeze-frames.
In 1986 Kodak scientists invented the first megapixel senor. This senor was capable of recording 1.4 million pixels. These were capable of producing a 5 x 7 inch digital photo quality print. In 1987 Kodak released 7 products that had the ability to manipulate digital images.
In 1991 Kodak in partnership with Nikon, released the Nikon F-3 camera. This camera was equipped with a 1.3 megapixel sensor by Kodak. This shows how the history of digital photography merged scientific know-how to produce a digital camera.
At about this same time Logitech produced and released their Dycam model with black and white images. Apple produced a digital camera that could transfer images to the computer from the camera.
This is the short version of the history of digital photography. Today 30 years after the first digital camera was produced and released digital photography has changed our lives. The next time that you buy a digital camera you might want to see what other information you can find out about the history of digital photography.
