Agfa Scanner

Home Up Agfa Scanner HP ScanJet Reliscan 2412    

The AGFA Arcus II scanner is the best flatbed scanner in the department.  It has an optical resolution of up to 2400 dpi, and can scan transparencies as well as reflective originals.  If the Nikon LS-2000 is not available to scan slides or film, this scanner is your best bet.  It is located in the Research Lab.
  1. Turn off the computer and all peripherals.
  2. Turn on the Arcus II.
  3. Boot the computer by pressing the power button on the front of the computer.  Please note that it is absolutely vital to turn power on to the scanner before turning on the computer.  If the computer cannot find the scanner, you must shut the computer off - rebooting it will have no effect.
  4. With the computer started, use either the desktop icon or the Start menu to start Adobe Photoshop.  
  5. In Photoshop, choose File:Import Twain 32...   This will start the FotoLook software.

 

The FotoLook software is relatively complex.  The window is shown to the right.  Starting at the top:
Original: You have 3 choices, Reflective, Transparent, or Negative.  Reflective is used for material printed on paper, transparent for slides, and negative for negative film. Special instructions for slides and negatives are found below.

Mode: 4 choices:

 

Line-Art is for black & white drawings; Gray-Scale for b&w photos, Color RGB for most color images, and Color CMYK if you know what output device you will use and have set it up.

Bits per Color affects how many colors are displayed.  The choices are 8, 10 or 12; a larger number means more colors (and a more realistic image) but larger file size.  8 should be sufficient for most images, but if the color seems blotchy, try setting it to 10 or 12.
To scale the image, set the ScaleTo at 100% and select an input corresponding to the number of lines per inch on your output device (72 for a monitor, 600 or 1200 for a color printer or laserwriter, respectively).  Set it between 400 and 600 to scan slides or negatives.
The Range, ToneCurve, Sharpness, Descreen and Flavor options are advanced settings.  You should set the Range to Automatic (not Dmin/Dmax as shown above).  Ignore the others for now.  If you are scanning Line-Art you will see different choices.
Click on Preview to get a preview of the image.
Using the mouse, draw a rectangle on the preview image of the area you want to make a final scan of.  
Click on Scan to scan the image.  A new window will open in Photoshop with the scanned image.
You can make several scans before returning to Photoshop.  You cannot edit any of the images opened in Photoshop without first closing the Fotolook window.
 
Advanced Settings:

If the instructions above do not provide a satisfactory scan, you can use the wizard to set up the scanner.  Select the area you want to scan, then start the wizard using the wizard button on the toolbar.

Among the settings that you can adjust are the descreen settings, useful if the original is a newspaper or magazine photo (which is actually composed of small dots.

If you are scanning slides or negatives, the transparency adapter of the Arcus II is built in.  It does not cover the entire glass, however, so a special overlay is available to lay on the glass.  This forces you to put the transparencies in areas covered by the transparency lamp.  There are also several film holders to hold film of various types flat on the screen.  When scanning slides, I typically lay 4 to 8 slides on the Arcus and scan them all at once.  I then cut and paste from this composite image in Photoshop.  For slides or negatives, you will want to set the input ppi higher than 100; typically settings of 400 to 600 will give you a decent-sized image.  The preview and scanned images will be dark.  To fix this, in Photoshop:

  1. Highlight the image area of one of the slides.
  2. Select Edit:Copy from the menu
  3. Select File:New from the menu.
  4. Go to the new file (which is automatically sized to accommodate the image).  Select Edit:Paste from the menu.
  5. Now select Image:Adjust:AutoLevels from the menu.

These two slides were scanned in with different scanners.  The slide on the left was scanned in using the Nikon LS-2000; the slide on the right was scanned in using the Agfa Arcus II:
