![]() ![]() Typically, detail is lost in both the highlights and shadows, increasing contrast. And duping always results in a loss of quality. In olden days, the only way to copy a slide was to dupe it. For the i900, Microtek uses two 1600-dpi CCDs to get to 3200 dpi. Manufacturers achieve resolutions greater than that by stacking CCDs at a half-pixel offset. In fact, 2400 dpi is the current limit for 8.5-inch wide flatbeds. The i9x3200 dpi optical, so at 3200 it qualified. So the low number of the scanner's optical resolution had to be a least 2400. To get an 8x10, you have to be able to scan 2400 dpi (and some people think math isn't our thing). If you scan a 35mm film frame at that resolution, your maximum enlargement for a 300-dpi dye sub printer is 4圆. Inexpensive flatbeds usually boast something as low as 1200-dpi optical resolution (although the trend is upward). 21, 2001 issue for more detail on the following important features. Take a look at Kim Brady's Guide to Desktop Scanners ( ) from our Sept. Of course, there are a few other attributes it needed to qualify. Most importantly, it really didn't care how big a transparency we wanted to scan. It featured the same dual bed design of the old Agfa and, at $599.99 list (minus a $50 rebate coupon at ), was closer in price to the Umax. This time we went for a pretty interesting product from Microtek ( ), the ScanMaker i900. We got great results from an expensive Agfa Dual years ago and miserable results from an inexpensive Umax with a transparency adapter. We've scanned transparencies on a flatbed before. It's amazing what mankind has managed throughout history to fit in a 35mm mount. Some of them were almost as large as the mount. Our film scanner was a 35mm scanner.Īll of our old slides were in 35mm mounts but they weren't all 35mm frame size. Just how feasible would it be to scan a bunch of old slides with a film scanner? Since we had already discussed using your digicam to copy slides, we wanted to use a film scanner this time. We had planned to squirrel away the winter scanning a few hundred old slides.
