Digital cameras, or digicams, have become the standard for photo taking, slowly eliminating the need for traditional film cameras. Even if you are considering replacing your old film camera, you are going to want to pay close attention to the one thing that remains a constant between the two types of camera on the market: resolution. Most photographers cringe when they hear that word because it is an important part of how clear and sharp a photograph turns out when they are developed – either in a computer screen or in a photo lab. When it comes to digicams, the resolution is the amount of pixels that fit in an inch of space. The more pixels in that space, the sharper and more vivid the picture is going to be.
When you consider how a picture looks on a computer screen, you know that the more pixels covering an area make the image look better. This is the same concept used in the way a digital camera recreates the image it took a picture of. A picture that has 100×100 pixels in a one inch area is going to be beautiful compare to a picture that is 100×100 pixels spread out over four inches. This is why when you print pictures from a photo that has been scanned into your computer and enlarges sometimes comes out grainy or blurry. If you enlarge something too much, it will distort it, changing the resolution.
The resolution of a digicam is in megapixels. That means there are 1,000,000 pixels in an inch of space. The more megapixels you have, the sharper the picture will be. If you are going to be using your digicam for everyday photography and picture printing, you want to make sure you purchase a digicam that has a resolution around thee to four megapixels. This will give a clear picture with vibrant color without strapping your wallet. If you are going to use your camera for professional photography, you will definitely want higher than four megapixels to ensure the best photos you can get.
Deciding on the resolution for your digicam is really going to depend on how good you want the hard copy to look. High-resolution digicam photos are going to look better than a photo taken from a standard film camera, but low-resolution digicam photos should stay displayed on the computer and never printed. When you are reading the information on how pictures will print from your digicam, you want to make sure you have at least 300 pixels per linear inch of print to get good resolution. The higher your pixels, the better the picture will be. Before printing, make sure your printer can handle the higher resolution. Some cannot handle anything over 600 pixels per inch resolution and will cause your computer and printer to freeze when trying to print.
