Because of the high
resolution, these files may be quite large. Please use the file sizes
given next to the text link to estimate the amount of disk space
required to save all desired images and the length of download time.
Take the File to a Service Agency
You may avoid considerable frustration if you consult with your
institution's photography or computer services department before
proceeding further. All images in the Atlas exist as JPEG files, an
image format developed by the Joint Picture Experts Group. The use of
this widely accepted format facilitates the transfer of images among
many different computers and operating systems. Your photography or
computer services personnel may be able to use the downloaded JPEG
files without any additional work on your part. If this is the
situation, simply follow their recommendations on how best to send them
the files. Usually this will require a floppy disk for smaller images
or other removable media (e.g., ZIP or SuperDisk) for larger files.
With cooperation, network transfers also may be possible.
If your services department cannot deal directly with the
JPEG files, you will need to prepare each slide on your own computer
for eventual transfer to the film recorder. Departmental personnel
should be able to recommend presentation or image manipulation software
that their equipment will recognize. These might include Microsoft
Powerpoint, Corel Presentations, or Harvard Graphics. You will need to
lay out each slide by importing the appropriate JPEG image, and the
details of this process will differ among the various packages. Be sure
to set your software to the proper aspect ratio. The width-to-height of
35-mm slides is three-to-two, and most presentation packages include a
slide format with the proper proportions. Once your presentation is
complete and saved, the resulting file can be sent to photography or
computer services by one of the means discussed above.
Image software may offer you the opportunity to reduce the size
of your image, perhaps by converting to an alternative format or by
decreasing the number of colors. Such options should be avoided,
because they may also reduce the resolution of the image and produce a
slide of lower fidelity.
