In case of copy rights, I guess most of the people who creates some kind of artwork, do not want someone to use his/her artwork without permission.

Watermarks can sometimes be a solution to prevent such not permitted use of their artwork. However, I have a confusion in my mind about watermarks (deviant art ones and also the ones done by some design software...). I hate actually putting watermarks, but I could not find a reasonable solution about not permitted use of images.

Well actually, art is a matter that should be shared, normally I do not mind someone use my artwork to create another artwork, but it is naturally expected that asking for permission. The answer would generally be "OK, u can use it as long as credited me". But, it is a matter of ethics that not everyone is kind enough to ask for permission. In this respect, a mind confusion is appearing about use or not to use watermarks. I have thousands of photos waiting for upload, however since I could not get rid of this confusion, I am still not sure to upload or not.

I want to learn about your ideas about this. And if you have any suggestions, i will be glad to hear them. Thank you very much for your interest.

Enjoy photography, enjoy art!
