Non-profit/Classroom Use

I encourage use of my photographs for science education and other non-profit uses by students, teachers or researchers. Images may be downloaded with watermark or you may contact me for access to un-watermarked original images for the lectures, scientific presentations, and school projects. The exception is if these images will be part of lectures or presentations that will be uploaded to the internet for potential commercial use by another party (eg. your lectures will be sold as part of an on-line course to benefit your college or university). In each case the citations of image source – Duff – in keeping with good scholarship is requested.

Non-profit organizations are also welcome to request use of photography usually free of charge with proper attribution.

Personal and Commercial Photo Licensing

Images may be licensed for personal (blogging, personal web design, fine art printing for individual resale) or commercial (company webpages, books, merchandise, magazines, etc.) by contacting me ( 

Please be aware that I do not allow my photos to be uploaded to sites that apply a blanket Creative Commons license (Wikipedia, Wikispaces or any “free” photo-stock sites) other than those I have contributed myself.
