Technology considerations:
Specimen images were created by direct scanning at 600
dpi. The small- and medium-sized images were produced by
downsampling from the original scan. All images have been
corrected in software for contrast and brightness, and have been
saved as slightly compressed JPEG files. Therefore, a small
amount of variation from the original specimen is to be expected.
The uncorrected, original scans in TIFF format are available upon
request.
Copyright information:
All specimen images are copyrighted by the Illinois
State Museum Society. They are made available for educational and
scientific purposes only. They may not be republished
electronically or in print without the written consent of the
Illinois State Museum Society.
