Copyright and Usage Policy

All images and site content are Copyright 2004-2011 by Dan Lessmann unless otherwise noted for specific content.

If you would like to use one or more of my photographs by another arrangement, please review the terms below first, and then feel free to email me with the following information:

  • Your name, address, phone number and organization.
  • A detailed description of the intended use including your intent to use the photograph for editorial, educational or commercial use.

Here are the terms for use of my photographs:

  • If all you want to do is place a hyperlink to one of my pages on your website or use a photo for wallpaper on your PC's desktop, there is no need to contact me for permission.  I only need to hear from you if you are going to display or print or otherwise use a photograph.

  • All other use must be by my written (e.g., email) permission.

  • If the use is for non-commercial or educational purposes, say for a public school, non-profit organization or local club presentations, etc., I generally do not charge a fee.  I only ask that I be given credit for the photo in the form of a byline and copyright statement (i.e., "Copyright 2011 by Dan Lessmann").

  • If a photograph is to be included on a web site, I will ask that in addition to the above byline, wherever convenient, a link be placed to my website:  Also, please email me a link to the page where the photo appears.  This is purely for my interest only as I like to keep track of where my photos are used.

  • If the photograph(s) are to appear in printed materials, I would like to receive a copy for my files.

  • For commercial uses such as a publication or advertisement produced with the intention of making a profit, please email me with detailed information regarding the use and I will quote a usage fee if the particular form of usage is acceptable.

  • In all cases, unless we explicitly negotiate otherwise, usage is limited to what I specifically grant permission for and I will retain the copyright on all of the photographs.
