Ofoto is an easy to use graphics scanning application available in CIRCA's primary Macintosh labs. This handout describes Ofoto's basic one-button scanning procedure and some of its other features.

Basic one-button scanning

1. Turn on the scanner and restart the Macintosh.

2. Lift the scanner lid and place the original face down on the glass with the top of the picture toward the hinge. Close the lid.

3. Open Lab Ofoto (in Lab Software:Macintosh:Utilities).

4. In the Scan Controls palette, select the calibration for your printer or display, then click Autoscan. While you wait, Ofoto automatically prescans, determines whether the original is color, grayscale, or line art, chooses the scan settings, scans, sharpens, straightens and crops the image.

5. Select Save in the File menu to save the scan on disk.

Other features

for a quick look. During Prescan:

* Hold down Option and click Continue to jump to the next Autoscan step.

* Click Stop to finish the prescan.

* Click Cancel to erase the prescan.

* The type of image you want your scan to be (color or grayscale photo, or line art).

* The number of colors or grays to scan (scan bits).

* The number of dots to scan (scan dpi).

* The number of colors or grays to print (print bits).

* The number of dots to print (print dpi).

* Turns the automatic operations on and off.

* Controls scan quality.

* Makes your next scan use the same tone settings as the previous one.

* Scan line art at 8 bits to make threshold adjustments (1 bit default shown).

* Scan vertically or horizontally.

* You can sharpen the image more than once.

* Focus if some areas are blurry.

* Invert to make a negative image.

* Change the size of the image.

* Adjust brightness and contrast, highlight and shadow.

* Correct a tint or color cast in the image.

* Adjust contrast and brightness.

Use the selection rectangle to choose part of the image to crop, copy, cut or clear (and optionally "show selection controls" in the "windows" menu to adjust your selection).

Use the lasso to choose part of the image to crop, copy, cut or clear.

Use the grabber to move the image.

Use the zoom tools to look closer or for a more distant view. Or use the "window" menu to change your view of the image.

Use the angle tool or use the "Image" menu to straighten, rotate, or flip.

Use the Pencil to click individual dots (zoom in to make it easier).

Use the eraser to clear parts of the image.

Use the dropper to pick a color from the image. The color is displayed in the color patch.

To use your images in another application, use a file format the application uses:

* PICT for most applications (uses ColorSync)

* TIFF for some applications

* EPS to print on a PostScript printer

You can compress saved images to conserve disk space. Compress PICT files with:

* Photo - JPEG (the best quality for full-color images, but compresses slowly)

* Video (faster than JPEG, but lower quality)

* Animation (best for images with large areas of solid colors)

* Graphics (best for line art and dithered images)
