    -- at "create with your photos" - hit close [X out]
  3. Under File go to Import and select WIA Epson GT -15000 [scanner box opens]
  4. adjust settings for your scan: mode, (color, grayscaleetc.) or custom, [see Making Better Images discussion, below]

Troubleshooting

software can't find scanner, message "Could not Locate Scanner" appears on screen 

  1. turn the scanner off and on (grey button lower left side of scanner).
    Wait approx. a minute
  2. Repeat scan from "select WIA Epson GT- 15000"

Images are too light/dark

  1. use image enhance or auto levels on toolbar

Images sre too small/big

  1. change resolution and rescan, or
  2. reduce or enlarge through Photoshop tools
 

Making Better Images

Black & White Scans - always choose "gray scale" over black-and-white mode options, even though original is b/w.
 The "black & white" scan mode reduces every part of the image to black or white pixelation, losing fine detail that gray scale preserves

Resolution - resolution will change the size of your saved image.  As a rule of thumb:

150 - adequate for b/w printing
300 - good for more color image online studying and printing
600 - high resolution - at this size, you might also want to save as tif (image size will be large)

- use option #4 "Custom settings"

Enhancing Color - the bright light used in scanning tends to wash out the original color of the image

After scanning, we recommend clicking the Autolevel adjustment to return the colors closer to the original.

[after image is scanned]

  1. at Enhance toolbar tab, pull down Adjust Lighting
  2. Brightness/Contrast

"Brightness" = lightens or darkens the page

"Contrast" = a form of sharpening

 

Jpeg or TIFF?

What you intend to do with your image will determine what format you should select

Jpeg - compressed file, small memory size
     Jpeg's are the most common format for images.  They are also the most unstable.  If you'll likely be saving and resaving (or re-editing) the file, the image will degrade.  Jpeg's are the smallest memory, so they're the best to email and store.

TIFF - large size (archival images, stable)
     TIFFs will not degrade with with resaving and keep strong digitization.  They are large and less likely to change over multiple savings.
