Why do people who post their work spoil them by putting copyright notices across the images
Once again, this morning I see an uploaded painting completely ruined by with a copyright notice pasted right across the middle. There was a time when a discrete signature was sufficient to indicate who owned the copyright. Would they enter a competition by submitting an image overwritten with "Copyright J Bloggs"? No. Would they ever sell a painting with "Copyright J Bloggs" scrawled across the middle? No. Do they insist that paintings reproduced in "The Artist" are emblazoned with "Copyright J Bloggs". No. Does the Saatchi Gallery despoil images of painting for sale with copyright notices? No.
Curiously I randomly samples 2 pages from the website of the artist who triggered this blog. Only one out of about 40 images was despoiled with a copyright notice. But to get back to the point, what you do on your own website is up to you, but if you are that concerned about copyright that you feel it necessary to spoil your images, don't post them on an open website whose purpose is for others to enjoy the artwork.
