This article is about using flatbed scanners for natural history imaging, and the inspiring work of one man, Alfred University artist Joseph Scheer, a fine arts print-maker who turned his attention to the dark side, the nocturnal world of moths from Arizona and Sonora, Mexico. Think of flatbed scanners as wide-field microscopes capable of higher magnifications than macrophotography, and easier to use than setting up tripods, cameras with close-focusing lenses and light stands in a studio. Lighting is everything, and scanner light is uniquely different from using film or DSLR cameras. When viewing a print made from a scanned image, a first-time observer often thinks the image was created photographically, but something is not quite right. Their unique sunlight-balanced even illumination, as the fluorescent tubes pass below scanned objects, yields dramatic lighting difficult or impossible to reproduce with copy stands, studio lights, cameras and lenses. A few scanner models have enhanced depth-of-field capabilities and can accommodate thicker objects, up to several centimeters. Scanned objects need not be monochromatic or paper thin. Boring! This barely scratches the surface of what modern flat bed scanners, and their software, can produce for working artists, scientists, naturalists and students. Or, someone attempts to copy a color photo on a page torn from a magazine and is disappointed with the results due to the halftone printer's dots because their scanning software does not have a de-screening algorithm. Once in a while, someone places a color photograph on the scanner glass, closes the lid and makes a color scan for importing into Photoshop™, LightRoom™or another image-editing program. They are routinely used to make copies of flat objects, typically paper documents including scanned receipts for accounting or similar purposes, usually as black and white or grayscale images. The use of flatbed scanners is offered as a relatively new method for visualizing small objects while acquiring large files for creating archival inkjet prints for display and sale.įlatbed scanners are routinely used around the world millions of times daily, found in virtually every business office and many homes. Highlights of the Fulbright sabbatical year of professor Scheer in Arizona and Sonora, Mexico are presented, along with comments on moths in science, folklore, art and pop culture. Collecting and preparing moths, and other objects, for scanning are described. Representative flatbed-scanned images of moths are illustrated along with techniques to produce them. The work of pioneering scanner artist, Joseph Scheer from New York’s Alfred University is highlighted. The special attributes of certain scanners, to image thick objects is discussed along with the technical features of the scanners including magnification, color depth and shadow detail. They are not just for trip receipts anymore. Opening angle can also be adjusted depending on the book size, in order to optimize scanning process.During the past decade a few artists and even fewer entomologists discovered flatbed scanning technology, using extreme resolution graphical arts scanners for acquiring high magnification digital images of plants, animals and inanimate objects. Self opening and closing motorized glass plate preserves originals. Motorized book cradle with two lifting columns is designed for books up to 180 kg. An additional LED bar ensures even illumination on the whole scanning area. Two high-resolution CMOS sensors give superb quality full format scans within a seconds.
