Scanning

Scanning is a process of sampling and recording the dots and color values that make up an image. The image is scanned and sampled line by line (rasterization) and the results are described as a bitmap file. Images are typically scanned at resolutions between 50 to 1200 Dots Per Inch (DPI). Bitmap files are commonly used in paint programs or image processing programs like Adobe PhotoShop.

What Can Be Scanned

Two dimensional opaque objects up to the size of a flatbed scanner (8 1/2 x 14) can be scanned in one pass, ususally up to legal size. Materials to be scanned include:

• Photos
• Artwork
• Drawings
• Text

Transparent materials, such as slides or negatives can be scanned with a special slide scanner or a flatbed scanner that has a transparency adaptor.
