file(s) which get larger and larger as you send more and more data to ADOBE
PHOTOSHOP. Even if you have a system with hundreds of megabytes, or even more
than 1 gigabyte of DRAM, switching between multiple ADOBE PHOTOSHOP image
MICROSOFT WINDOWS, each holding a 50MB image, can be time consuming and
awkward. If you are performing high resolution scans of several frames, it is a more
efficient workflow for you to send the image files directly to your hard drive. Consider
using the “Scan to File” feature of the RFS 3600 software. After scanning to your hard
drive the frames you want, exit the RFS 3600 software and open the image files one or
two at a time in ADOBE PHOTOSHOP.
Next, you must have sufficient Virtual Memory allocated for your OS. Specifically, in
MICROSOFT WINDOWS, this is your “Paging File Size”. Use the MICROSOFT
WINDOWS Help system for information regarding the Paging File. If your Paging File fills
up, the film scanner’s software will not be able to continue to perform scans. If your
MACINTOSH has less than 1 gigabyte of system memory (actual DRAM), turn on Mac’s
Virtual Memory. Select the Memory Control Panel under the Apple Menu. Click the “On”
radio button for the Virtual Memory and enter size box a value equal to the Mac’s built-in
memory.
Your assignment of Memory to ADOBE PHOTOSHOP will affect its performance. On a
MACINTOSH, perform a Command + I keystroke on the ADOBE PHOTOSHOP icon. On
the resulting pop-up, select Memory from the “Show:” dropdown. If your MACINTOSH has
less than 1 gigabyte of system memory, enter 80MB to 100MB (80000K to 100000K) in
both the Preferred and Minimum Size data boxes. Do not exceed 100MB. If your
MACINTOSH has more than 1GB of DRAM, assign 900MB to ADOBE PHOTOSHOP.
For MICROSOFT WINDOWS, start ADOBE PHOTOSHOP and open the Memory and
Image Cache preference dialog box. Assign a fixed percentage of memory to ADOBE
PHOTOSHOP. However, ADOBE PHOTOSHOP will only use the amount of RAM equal
to or less than its scratch disk space, no matter how much RAM is installed or allocated to
it. “ (from www.adobe.com)
