“You have to be sure of yourself and your equipment.” DANICA PATRICK Racing Star, Go Daddy Girl®
Cruising at the Daytona 500 Is Like Scanning Your Still Images (Well...Sorta!)
If you are going to jump into a supercharged racecar and zoom around a NASCAR sanctioned track at nearly 200 miles per hour, like Danica Patrick does, then you can understand why there's a need to be certain about both your abilities to drive and the equipment you're driving!
And, though scanning still images doesn't exactly move at the speed of a NASCAR buggy travelling around the Daytona Speedway, Danica's concept still applies. You must be sure about your abilities to be able to properly scan photos while understanding the important components of the techniques and equipment used to accomplishing the digitization feat.
Since all scanners have a number of components in common, taking the time to delve into the nature and meaning of scanning basics can go a long way to help add this level of confidence. We have found 4 websites offering the basics of scanning that have an abundance of useful information to help. Though some of these sites may be slightly dated, the information contained within them is fundamental and remains useful.
