VueScan User's Guide

step #2 above, use a film frame that has an area that would print as pure black for

negative, or pure white for slides.

Regardless of the lighting conditions, shutter speed and aperture of each frame, you should use

these fixed values for exposure and film base color for scanning all frames on the roll of film.

Once you have the exposure and film base color fixed, you can scan the whole roll of film using

these values.

 If you're using the same lighting for all the frames on the roll (or a subset of the frames),

you can lock the color balance by scanning the brightest frame in the series and then

setting the Input | Lock image color (p. 62)option. This will lock the black and white

points for the scene, and will produce consistent colors for all the frames in the series.

This is also useful if you're scanning panoramic scenes that have all been taken with

the same lighting, shutter speed, and aperture, or if you're scanning a series of studio

shots taken with the same lighting, shutter speed, and aperture.

 To optimize workflow, scan to raw files and experiment later with color correction. Make

sure you first set Input | Lock exposure (p. 61)before scanning a roll of film.

 If you're saving raw scan files, you can turn off Output | TIFF file (p. 82) and Output |

JPEG file (p. 83). You may also want to capture the entire preview area instead of the

auto-cropped area by clearingCrop | Auto offset (p. 65) and Crop | Auto rotate (p. 66)

and settingCrop | Crop size (p. 64) to "Maximum".

 For quicker batch scanning, set Input | Lock exposure (p. 61) and clear Crop | Auto

offset (p. 65) and Crop | Auto rotate (p. 66). This will stop the Scan button from creating

a preview.

Scanner Profiling with IT8 Targets

Scanner profiling is the process of determining the precise color characteristics of a scanner or

digital camera. VueScan uses IT8 targets (also called Q60 targets) to do this.

IT8 targets are included with many scanners. You can also obtain IT8 targets from this source:

To profile your scanner or digital camera with an IT8 target:

1. Set Input | Task (p. 49) to "Profile scanner"

2. Click the '@' button next to Color | Scanner IT8 data (p. 76) and choose the IT8

description file that came with your IT8 target
