There are several different pieces of software used for scanning images. Some are made for a specific scanner, some are third party applications. Even with the differences, the steps for scanning anything are the same...
1. Place your object/image on the scanning bed.
2. Preview your scan.
3. Determine the resolution of the scan.
4. Choose the area of the scanning bed to scan.
5. Modify any additional settings such as the descreen filter.
6. Scan.
Here are some tips for how to scan different types of documents, photographs, objects, etc. We'll cover film scanning later...
Photographs - Always scan as full color (even if the original image is black and white). This will add resolution. You should not apply any filters or special adjustments when scanning a photograph.
Three dimensional objects - Scan the same as a photograph.
Images from print media (postcards, magazines, newspapers) - use the descreen filter. This will abate the presence a moiré pattern in the final file. Most scanning software contains a descreen filter with settings for magazine, newspaper, fine art print, etc.
