If you are new to digital photography or scanning - then this article is for you. This will show you the basics of all you need to know in order to get started. The author prefers that you use a scanning service if you have a lot of photos to scan - and when it also comes to scanning slides to photos [http://memobase.co.uk].
Digital Photo
A digital photo is made up of millions of pixels. Pixels are essentially the "atom" or building block of a picture. Pixels are actually picture elements and have tiny sections that consist of
color or tone. They are usually depicted on a two dimensional graph and are usually represented by the use of squares. Every pixel consists of three values: red, green, blue, or RGB. RGB is information used to select the color of each pixel. A goodexample of RGB is a 24 bit color image. These RGB values are made of 8 bits for green, red,and blue. To show the range of these bits, 256 color options exsist from 0 to 256 scale. Next,the grid, in which all of the pixels are contained,is yet another important element. The grid is really the housing for the "atom" or pixel.
Scanners and Resoultion
Scanners operate by reading color information from the photo selected and record the information in a pixel format. This is how resolution is created because the information is gathered by the scanner. In definition resoulution is really the final product of the picture. The scanner and resolution work together in creating a good picture quality making the images clear.
Megapixels
What in the world are megapixels? Well it simply means one million pixels or it is also seen in the abbreviation MP. If you look at the information contained on a digital camera you would find that they are rated by megapixels. To find the number of megapixels get a photo and just do the simple math equation length times width (in pixels) and there you have it.
High Resolution
An amateur might guess that a higher resolution is the best choice, however that is not always the case. It really depends on what type of picture is being scanned. A lot of photos were taken with
today what we call obsolete equipment. Now take that photo with a high tech piece of equipment and you are creating more detail than the photo originally had. This is one example why high resolution
is not always the best way to go.
Finally, what kind of resolution would fit best with my photo? Well it really depends what application you are going to lay on that photo. Some people would like to send these photos through their email or make CD-ROMs and others would actually like to print the photo out on a sheet. The resolution will be different for both of these people, so keep that in mind when you are deciding what resolution you want.
