UMAX PowerColor Quick Start Guide

This guide will introduce you to the fundamentals of UMAX’s PowerColor Photo and Press edition
professional scanning software. You will launch the application, perform basic setups, and execute
an Overview scan and Region scan using some basic tools and commands. This guide begins with
basic operations and then moves into some of the finer points of the software.

Image Selection Tools

Probe Region: The Probe (or Pointer) tool is used to select items and to move around the image to 

sample pixels. The tool deselects the Crop and Zoom tools.

Zoom: Click on the image with the Zoom tool to enlarge the image for more precise examination of a 

region. If necessary, resize the image window to accommodate the new view. The magnification is shown 

at the bottom left-hand corner of the image window. To reduce the view again, hold down the Option key 

(Macintosh) or Control key (Windows) while clicking on the image with the Zoom tool. Note: The point 

where the Zoom tool is clicked becomes the new center of the image in the window.

Crop Region: Use the Crop tool to select a portion of the image, for example to cut out the clack 

edges of a film frame or tape used to hold images on the scanning surface.

Auto Range: Automatically adjusts the tonal range, setting the highlight and shadow points.

Pick Neutral Point: Uniquely selects multiple gray points in an image by holding down the Option key

(Macintosh) or Control key (Windows) and clicking on quarter, mid, and three quarter tone values.

Highlight Value         

Shadow Value: Automatic values for each image highlight and shadow 

range are made with both buttons selected (default setting). Deselecting either button will result in a new 
auto range without the deselected value. Edit/Undo, from Main Menu reverts to last values.

Refresh: With automatic updating off, click on the Refresh key to update the active region with all 

changes since the last update.

Queue Manager Tools

Prescan all: Batch previews all the regions in the Queue Manager

Final scan all: Batch scans all the regions in the Queue Manager

Prescan one region: Previews the single region located above the icon. During scanning the region’s 

Preview button appears red, green and blue. Once the preview is complete, the buton turns all red.

Final scan one region: Scans the single region located above the icon.
