There are various types of scanners available that let you transfer your image onto a computer or other medium. You can scan photos, documents, book covers, negatives and slides. Some scanners have controls which allow you to create image files designed for how you plan to use them such as printing, copying, emailing, making a PDF file or uploading to an internet site. You can also sharpen and color correct your images while you are scanning them and some models will remove dust and scratches along with reviving old and faded images. Some scanners can also adjust image exposure and help smooth grainy images.
Built in slide and film adaptors are common so you can scan straight from your slides or negatives. Scanners come in various sizes, shapes, speeds and models.
They can range in price from about $50 to over $10,000.
