Nikon Slide Scanner

Quick Instructions:

The slide scanner is plugged into the iMac on the left in the user area. You no longer need to be logged in as an administrator to use it.

1. Turn on Nikon Slide scanner. The power button is in the lower right corner.

2. Click on the Nikon Scan 4 icon in the dock, it looks like a photographic slide.

3. Insert the slide into the scanner vertically (portrait mode) with the shinier side up (emulsion side down). You may want to blast it with canned air to get the dust off. Just be careful that you do it at a 45 degree angle so you don't damage the slide film.

4. The scanner will auto focus.

5. Click on the preview button.

6. In the tool palette, reset Curves by clicking the second to last icon to the right of the graph. Make adjustments if needed.

7. In the Tool Palette, under crop, set the DPI. For presentations or web pages use around 400 to 800. To get the most detail, set it as high as you can (about 1400). Note that this will make a really big file.

8. In the main window click Scan. For presentations or web pages save as a jpg. For high quality archiving, use Tiff.


The Twain plugin currently doesn't work in Photoshop, but when it does, use File, Import, Nikon Scanner after turning on the scanner.
