Choosing a Digital Camera

A digital camera is a lot different then your standard single-lens reflex camera or SLR for short. Before the introduction of computers and liquid crystal display or LCD screens; SLR’s were the standard issue for any photographer. Digital cameras operate not with film rolls like older cameras but with micro chips that hold the photograph as data. These new types of cameras deal with pixels to bring a picture together with much better quality than previously seen.
A pixel is like the cell of a photograph, it is the smallest part of a picture and thousands of these make up a picture. The resolution of a picture is also important to note when looking at picture quality. Display resolutions are often followed by a number such as 1280×1024. This number tells how many columns and rows of pixels there are in a picture. The higher the number the more clear the picture.
When choosing a digital camera all of these are important but on a camera you’ll see a number followed by the word megapixels. In order to find out how many megapixels you need to print a certain size photo you can use a math equation. First you need to know that DPI (dots per inch) helps determine how good of quality the picture will be. The higher the DPI and megapixel number the better the quality and size.
Anything that’s 150 DPI is going to be an average quality picture. 200 DPI is good and 300 DPI is extremely good quality. One megapixel will give you smaller sized photos where as eight megapixels will give you large sized photos. In order to find what you are looking for follow the below example for an 8 x 10 inch printed photo:
• Take 8 x DPI# = A
• Take 10 x DPI# = B
• A x B = Megapixels
So if we wanted to get a 300 DPI image on an 8 x 10 the equation would be as follows:
• 8 x 300 =2400
• 10 x 300 = 3000
• 2400 x 3000 = 7200000
The first number in the megapixels will be 7 and that’s the number of megapixels you’ll see on a camera in the store. You may see numbers like 1.2 MP or 8.1 MP. Knowing the equation to determine what size of photos you want will help you to find out exactly what amount of megapixels you’ll need from a camera.
Benefits of Digital Cameras
One of the biggest benefits of using a digital camera is that it doesn’t take any film. Old film takes a while to develop and can come out ruined or with only a few copies. Digital pictures can be resized, copied as many times as you want, and you get to see the pictures before they’re developed. Almost all digital cameras today allow you to review your pictures before you print them. This option allows you to delete photos you don’t want and choose the size you want them printed out as.
Most digital cameras come with a cord that allows you to plug it up to your personal computer. This is another great advantage to digital cameras since you can fill the whole camera and put them onto your computer for storage. These types of cameras come with chips called memory cards that have a certain amount of space on them. Once this space is taken up you can simply offload the pictures onto your computer.
These cameras come with a standard memory card that isn’t usually very large. In order to store more photos as one time you’ll have to purchase larger memory cards. It’s not just the amount of photos you take but the quality of photos you take as well that eats up the storage. Better quality and larger sized files take up more space on the memory card and should be taken into consideration when purchasing your digital camera.
