Scanning the slide fantastic
Article Abstract:
Desktop slide scanners offer the best combination of image quality, scanning speed and price for professionals who work with transparencies ranging in size from 35 mm to 4-by-5-in. Seven models are briefly discussed, ranging in price from Mikrotek Lab Inc's $1,299 Scanmaker 35t to Leaf Systems Inc's Leafscan $17,000. Most offer 2,000-dpi optical resolution. Blowing a 35mm image up to poster size calls for more resolution, however. 'Interpolated' resolution, in which the scanner inserts pixels and 'guesses' their color, is generally inadequate for continuous-tone images. Most slide scanners internally handle 30 to 48 bits per color. Users should also be aware of the density range their print shop is capable of and not buy a scanner that is overly sensitive. Film transparencies range from a minimum density of 0.3 to a maximum of 3.3 on a logarithmic scale that ranges from 0.0 to 4.0.

Slide show: slide scanners are the best tool for inexpensively capturing high-resolution data from 35mm slides and film
Article Abstract:
Slide scanners are an efficient and inexpensive way to capture film for high-quality digital production. Virtually all slide scanners offer resolutions of at least 1,950-dpi. Slide scanners do not handle reflective material. Many feature batch processing functions which can dramatically speed the scanning process. Specifications for color depth, density range, image processing hardware accessories, scanning method, and bundled software are all important features to be considered when comparing slide scanners. A slide scanner featuring 2,700 dpi resolution can be purchased for under $2,000, while a flatbed scanner with 1,000 dpi resolution is over $5,000. Many high-end slide scanners are being discontinued, as prices for flat-bed and drum scanners fall. Low-to-mid-range scanners continue to be successful.
