|Message from Dick Osseman
All pictures were taken by me and I do claim copyright for them (except for some of scanned publications in which pictures of mine appear, see my Me in print gallery). As for that copyright being violated: I am only partly worried. I would not like it if other people got rich using my pictures, without my getting a share. So far no one got rich there, so this is a mute point.
Possible use and what to do
Commercial use: This may be: use for books, commercial sites, television, articles, in short: any. Always send me an e-mail (firstname.lastname@example.org) and tell me about your intentions, never use the picture without my knowing so. I may hand the right over for free, I may ask for a fee. On that you should mail me and we'll work something out. I can often supply better high-resolution copies, though I do not like the recent craze for "high resolution" meaning I am expected to send a 16 MB file for a 1 by 2 inch picture. My formats are: 5 to 6 Mp camera's for the early digital years, later 12 Mp most recently 16 Mp Nikon D4. Slides I might scan again, but only in exceptional cases will I do so. And when requesting on one or more pictures, please do not use references like "that nice picture of ornaments on a medrese in Sivas", but send me the link to the single shot when in view, for example: http://www.pbase.com/dosseman/image/35088644 . Do this even when you refer to many pictures, it may be repetitive to you, but I have to locate pictures in a huge archive, and without such quick reference I'm lost.
Private use: If you want to keep my pictures just for yourself, or to show to a few friends: feel free to download them (right click on the picture and use a "save" option). Best quality is obtained in the "original" view you can set under a picture. You may wish to inform me you liked the pictures and mail me, but the sheer fact that you download them does not bother me.
I consider using the occasional picture in a blog private use, so I do not need to be informed. But there I would appreciate it if I'm mentioned as the copyright owner.
Professional use: by this I mean: using pictures in presentations, a thesis, a course. I like to at least have my name (as Dick Osseman) and if possible a link to my site shown. That is: if possible. In some presentations it would be silly, in a thesis it can easily be arranged. I like to be informed but it is not a must.
Semi-professional: Some people request permission to use pictures on a website they created and often run as a hobby. I would like to treat that as "professional", and thus be informed. However: if it is for just a few pictures, I do not need to be bothered. I think it is up to your conscience. Again: indicate me as the owner of the copyright.
