eric friedemann Posted April 7, 2012 Share Posted April 7, 2012 Ton, you might email and consult with Alain Briot who wrote this interesting article on protecting images: http://www.luminous-landscape.com/columns/they_are_stealing_our_work.shtml Link to comment Share on other sites More sharing options...

bobatkins Posted April 7, 2012 Share Posted April 7, 2012 <p>In a word, no.</p> <p>Just about all you can do to prevent useage is to put a large but faint © symbol across the whole image. Small copyright notices can easily be cloned out. </p> <p>I'm not aware of any technique that could render a watermark invisible on a monitor but prominent in a print made from a jpeg. You can do such a thing with images in a PDF format, but you can't display a PDF image on a web page. You need a format that has layers that can be viewed separately but can only be printed together. That doesn't apply to JPEG, TIFF, PNG or anything else you can display on a web page. There may be other proprietary formats than PDF, but then you'd need appropriate software to view and print them. Even then you could do a screen capture (unless, again you use some proprietary software for display etc.)</p> Link to comment Share on other sites More sharing options...

Tim_Lookingbill Posted April 8, 2012 Share Posted April 8, 2012 <p>This painting...</p> <p>http://farm4.static.flickr.com/3363/3571589962_60211b5b1f_o.jpg</p> <p>...viewed at 100% shows a clever way to embed a watermark so stealthily it doesn't distract from the aesthetics of the work while making it impossible to detect and clone out. I guess it follows the premise if you don't know it's there, it can't be changed.</p> <p>A photographer could apply the same technique by constructing a subtle wall paper pattern of one's name/logo on a Photoshop layer on a blend mode (Difference? Exclusion?) set to an opacity level that allows blending into the image making it undetectable at smaller zoom views. See below a screenshot of the above painting detail showing how well the tiny watermark is blended into the painting. </p><div></div> Link to comment Share on other sites More sharing options...
sarah_fox Posted April 9, 2012 Share Posted April 9, 2012 <p>Ton, I suspect you've already thought about the finely patterned watermarks on some checks that clearly show up as "VOID" when photocopied. I've tried unsuccessfully to create similar watermarks, but maybe fine patterning could be used to do something similar with our online images.</p> Link to comment Share on other sites More sharing options...
