Making Imagecorrections - Minolta Dimage Scan Multi Instruction Manual

AUTO-EXPOSURE LOCK (AE-LOCK)
Especially useful when scanning bracketed exposures, AE Lock lets you scan multiple images with the same initial
exposure settings. AE Lock saves the automatic exposure settings determined when an image is prescanned.
Subsequent images are prescanned using the 'locked' exposure settings.
• AE-Lock does not save exposure corrections made in the Variations, Histogram, or Tone Curves dialog boxes.
SETTING AE-LOCK
After prescanning the image...
1. Click on the AE-Lock button
• AE-Lock button can not be selected until an image has been prescanned.
2. Select another image, then click on the prescan button
• The scanner skips the setting exposure step in the prescan sequence.
• Images will be scanned using the AE-Lock settings until AE-Lock is cancelled or the scanner is reinitialized.
CANCELLING AE-LOCK
1. Click on the AE-Lock button
2. Click on the prescan button

MAKING IMAGECORRECTIONS

You can change the brightness, contrast, and color balance of the prescan and the resulting final scan.
The Dimâge Scan Multi software gives you three options for making such corrections:
.
.
to prescan the image again.
Variations
• This is the easiest way to make corrections and is recommended for beginning
users. It uses a visual display of contrast and brightness differences and you
choose the one that looks best. Color corrections are made by clicking on slider
bars.
• An unchanged version of the prescan (control image) and a preview of the changed
image (preview image) appear in the Variations dialog box for comparison.
Histogram
• The Histogram dialog box gives a graphical representation of the 256
brightness levels in the image for each of the red, green, and blue channels.
Using slider bars, the input and output levels can be adjusted to make changes
in the brightness, overall contrast, gamma (midtone contrast), and color of the
image. A control and preview image appear in the Histogram dialog box for
comparison.
Tone Curves
• The Tone Curves dialog box displays correction curves for the red, green, and blue
channels of the prescanned image. By adjusting these curves, the brightness,
contrast, gamma, and color of the output image can be changed.
• Making brightness changes first may eliminate the need for color corrections.
Reset All – Prescan Window
• The Reset All button, located in the Prescan window, will reset all the brightness,
contrast, and color balance changes made in all three of these modes.
