Which flatbed scanners have the best depth of focus (ability to scan 3D objects)?
by Darren Rowse No camera? No problem! Suppose you feel like taking a break from your camera, or maybe it’s just a rainy day and you don’t want to go out and risk getting the camera wet. Then you can use your flatbed scanner (assuming you have one) to make very interesting still-life pictures. In this post Kai Virihaur shows you how to get these interesting images using your scanner and everyday objects. Your scanner may have settings for both film (transparencies) and paper – then use the setting for paper. Now find some interesting objects, of suitable size to put on the glass plate of the scanner. You could for instance use seashells, flowers, seed pods, pine cones, leaves, pieces of driftwood, or even small instruments like old watches or compasses. You put your favorite objects on the plate and arrange them in some way that pleases you. Just be careful not to scratch the glass in case you are working with some hard edgy object. Ouch, now you can’t close the cover! No problem, just
Scanners are devices that can analyze two types of things: – Images, be these photographs, printed texts, or handwriting and drawings. – Objects (which would fit the scanning area, that is)- The scanner processes and converts all these into digital equivalents. One may encounter several types of scanners, nowadays: a) Flatbed scanners (commonly known as desktop scanners) are the most versatile and frequently used scanners. b) Handheld scanners are basically a more portable version of the flatbed type. However, these ones rely on the user to move them on the surface of the object. This type of scanner is not popular anymore because it provides a poor image quality. It is only proficient at quickly capturing text. c) Sheet-fed scanners are similar to flatbed scanners except the document is moved by mechanisms in order to be scanned by an immobile head. A sheet-fed scanner resembles a small portable printer. d) Drum scanners are commonly used by the publishing industry to capture high-res
