In the Barnes Computing Center, on the first floor of the lovely, unrennovated Bausch & Lomb Hall, there exists a color scanner for all to use. You need to have your ID card setup so that you can get into the room, and if you ring the door bell, someone might come along and help you...
When last I used the scanner, the Mac was pretty unorganized. The applications were not all grouped so that you could find them and the nifty pulldown menu for programs no longer existed.
The first thing to do is track down Adobe Photoshop and start it up.
Under the File menu, there is an Acquire menu. Choose TWAIN.
A program will start up and immediately conduct a pre-scan. When it finishes, set the options (if you don't like what it defaulted to) and redo the pre-scan. You shouldn't need to modify the settings more than once unless you want to.
You probably want to select color photograph instead of millions of colors. The latter only looks good on 24+ bit graphics cards.
The pre-scan of your image should now be displayed. Use the mouse to create a box around the image. This will define the actual image sent to Photoshop.
Hit the button which scans but is not the pre-scan button.
When it finishes, the image will be in Photoshop. Save in JPG or TIFF format. You may need to play with some Photoshop variables to allow saving to JPG (I think it needs RGB turned on...).
Find MacTCP and use it to transfer to holly or another machine which accepts connections from the Mac. You need to transfer in binary mode, I think...
