The purpose here is to offer some scanning tips about using your scanner, and to explain the basics for scanning photos and documents. It is also about the fundamentals of digital images, about the basics to help you get the most from your images from your scanner or camera. How it works, for those who want to know. Included here are the general questions that we've all asked about digital images. The material is about the basics of scanning, certainly not superficial, but it is not at all difficult either, it is just simply about how it works. It describes in plain language the things we need to know to efficiently get the most from our images, in the various ways that we can use them. Do realize that a digital camera is a scanner too, and its photos are already digitized (already scanned, so to speak, meaning, that first preference is to use your original camera file if you still have it). DPI is one of the first concerns. Many newbies want to scan a photo at the greatest possible resolution. We'll explain why that's the very wrong answer, with tips about how to choose a more appropriate answer to match the actual job. That and many other scanning basics are covered here, and it's intended help newcomers to graphics and scanning of photos and documents. There will be a little technique to learn, but when you've seen it once, then it's rather simple. Never used a scanner before?

Reporting of problems will be very much appreciated, thank you. I do try to help with questions about the basics or about my material, but I cannot help with the "what hardware to buy" or "my hardware doesn't work" questions, so those two types of email will necessarily get no response.
