       Flash set correctly

 

6.

 

Once the proper setting is found, it will not need to be readjusted even if 
the room lighting changes. If the subject distance changes these settings 
will need to be readjusted.  

     
 

Adjusting Flash Capture Quality 

 

1.

 

Adjust the “Red” and “Blue” scroll bars to adjust the image color balance. 
The values can be adjusted from -50 to +50. Positive values increase Red 
or Blue. Negative Colors decrease Red or Blue. These setting are 
remembered between captures and sessions and will be restored on the 
next capture without additional adjustment. 

 

NOTE: If large positive or negative values of Red or Blue need to be added, 
the “Flash Red” and “Flash Blue” adjustments should be set to minimize the 
values of these settings. See “Tips on Quality Captures”  
later in the manual.

If large values of Red and Blue are 
needed click the 

“Don’t Save”

 button 

and click the 

“Adjust”

 button. The 

“Test” dialog will open. 
 

3.

 

Set the 

Flash Color Correction

 Radio 

button for the setting (Fluorescent or 
Default) that is not being used.  
 

4.

 

Do not close the “Test” dialog box and 
take another flash capture. 

 
5.

 

Adjust the “Flash Red” and “Flash 
Blue” controls on the main dialog for 
color balance. Use the “Flash Color Correction” setting that needs 
the smallest adjustment of the “Red” and “Blue” 
 

6.

 

If desired this process can be continued by adjusting the “Flash 
Red” and “Flash Blue” controls in the “Test” dialog, taking 
another capture and adjusting the “Red” and “Blue” controls in the 
main dialog. 

 

7.

 

Please note that the Flash color controls only effect flash captures 
and have no effect on the live preview. 

 
 

Cropping Control 
 

The 

VALCam USB

 allows the user to set cropping parameters for both 

preview and capture. The live preview will display live video that 
corresponds to these parameters. The capture image will also conform to 
these dimensions.

 

 

These parameters can be set to match the picture box of the card design 
thereby eliminating the need for software cropping and speeding up the 
capture process. The efficiency of the process will depend on how the 
photo-id application handles image captures. If the cropping function of 
your photo-id software can be disabled, you can use the camera to crop 
and capture straight to your card.  
 
Another advantage of this feature is that the live preview will correspond 
to the actual “portrait” design of the card for a more pleasing and realistic 
rendition of the image.
