Most of the images in the SIMoN Photo Library are within the Public Domain (e.g., images taken by NOAA staff during duty hours) whereas other images retain the copyright of the owner. To determine copyright status of any image, look at the metadata under comments by the photographer. If information regarding copyright status is neither provided in the metadata nor imprinted on the image itself, then you can assume the image is in the Public Domain.
At present there is no fee to use images in the Public Domain. However, in ALL cases, credit MUST be given to the photographer as indicated by the photo metadata. If you have any questions, please contact Dr. Steve Lonhart.
