Although digital photography is a revolutionary new way to see the pictures, is still based on traditional photography and incorporates many of the same ideas to take. Both digital and traditional photography with a lens with which to fire light and a shutter that allows light into the camera. The big difference between traditional and digital photography is like a camera to capture the image.
In traditionalUsed> photography, a film that will be developed in a darkroom with the use of chemicals. This evolution leads to a "negative", then the press, so that the image used. Digital photography, what you can see an electronic sensor. And 'this electronic sensor that captures the image of the photo. Millions of pixels on the sensor, which converts light into a series. Instead of waiting to develop the imageA digital photo can be seen almost immediately in the camera viewfinder.
Digital photos using the number of pixels to determine the image quality. The number of pixels is often called "resolution" and is measured as the size 800x600. This is also known as the number of pixels per inch known. A typical solution for a computer screen is 800x600. This means that the screen can display 800 pixels from side to sideSide and 600 pixels from the top of the screen down. The total number of 480,000 pixels it would be. Digital photography used resolutions that are higher than the computer monitor, often resulting in millions of pixels. When a digital camera has a resolution of 2048x1536 has a height of 3.1 megapixels.
As already mentioned, the number of pixels. These numbers will determine the extent of colors that can be created. How, for example,Images that are black and white megapixels, which is only 8 bits to be represented. As with binary arithmetic, an 8-bit number can then enter a decimal number between 0 and 256 This means that the black-and-white images up to 255 shades of gray and black (may be 0) and may also have white tones (256).
Larger numbers represent the colors. For example, 16 bits per pixel to a color scale of different shades are 65,536, while 24 bits per pixel 16 mayMillion different colors. Today, most digital cameras have made use of 24 bits per pixel, however, have achieved some professional cameras, a color resolution, 48 bits per pixel, can create over 280 billion colors.
The quality of a digital camera is influenced by several factors. Most of the pixel resolution is considered one of the most important factors. You want to choose the correct pixel resolution for the size of the images thatPrint. 've note that although the number of pixels on the photo, not the images with larger less pixels per inch, will change. This will result in less detail in the image with the increase in size.
Photo Labs photo prints are 300 pixels per inch. This measurement standard, you can calculate the number of megapixels your digital camera that came from. Has the largest printing from a two-megapixel camera can be obtained (ie 300 pixels perinch) is a 5.8 "x3.8" picture. Which is lower than the standard 4 "x6" picture. A four-megapixel digital camera features, can be used to print photos up to a size of 8.2 "x5.4" approximately 300 pixels per inch.
You still have the ability to print larger photos. Please note that the photos are printed at 200 pixels per inch, is less clear, however, these photos will still be usable for many purposes. With this type of resolution you can get prints up to 8.7 "x5.8" with aTwo megapixels. And with a four megapixel camera can be found in a position to get the pictures up 12.2 "x8.2".
Now you have some understanding of the differences between traditional photography and digital photography, you can narrow your search for buying a camera used.
