Press the Save button to complete the scan. Once the first scan is done, press the Scan + button (to scan another page) Continue until if you’ve scanned all pages. Note that multi-scanning is the only way to increase the quality at the highest resolution, and that using Output | TIFF size reduction or Output | JPEG size reduction is a better way of producing quality scans at lower resolutions. Once VueScan detects your scanner, load paper on the flatbed or in the automatic document feeder. In this example Scanning at 1350 dpi throws away every other pixel and every other scan line, while scanning at 2700 dpi and setting Output | TIFF size reduction to “2” will result in averaging 2x2 blocks of pixels and increasing the number of effective bits of resolution by 2 bits. This is hands-down my favorite of the trio. Its single PDF user manual is also unusually detailed and helpful. It's cleaner, faster and more modern than its rivals, and leaves more room to preview your images. For instance, scanning at 2700 dpi and averaging every 2x2 block of pixels will result in a higher-quality 1350 dpi scan than just scanning at 1350 dpi. VueScan's UI has Basic, Standard or Professional modes, all three mostly using drop-down lists very logically arranged in two to five tabs. The second technique is multi-pass multi-scanning, which most scanners are capable of (however, some can’t accurately reposition each scan pass, so this may not always work well).Īnother useful way of getting multiple image samples is to scan at a higher resolution and then average adjacent blocks of pixels. Some scanners are capable of reading each pixel position multiple times before advancing the scan head to a new position. It will help you get started using your scanner and show some of the more advanced features that can make life easier. Press the Save button to complete the scan. If you're having problems scanning with your scanner, or if you have questions about how to scan with VueScan, this page is for you. There are several ways of achieving multiple image samples. Once VueScan detects your scanner, load paper on the flatbed or in the automatic document feeder. Crop your image to crop out the film borders (or use the Border Buffer setting in Negative Lab Pro to ensure the film borders are not included in the image evaluation. For instance, if you have a 10-bit scanner like the Nikon LS-30 and you read the CCD 4 times at each pixel position, you get effectively 12 bits of useful image data. VueScan is an excellent alternative for those users who need a software to control the scanner, because this lite program is compatible with more than 500 models. Each doubling of the number of pixels increases the effective number of useful bits of data by one. The basic idea is scanning each pixel more than once and averaging the pixels. After you’ve decided on the resolution of your finished image (or alternatively the pixel dimensions of your finished image), how do you maximize the image quality? There’s one thing you can do which involves longer scanning times, but capturing more raw data for each pixel in the finished image.
