Deb et al,

I think the message here is that applying the same watermark in the same place on each image (as your Digimarc droplet would do… yes, that’s still the terminology) is no longer a guarantee that savvy programmers can't strip out the mark in a body of images with the ease of a few lines of code. It’s an arms race, and for now, the ball is in our court. Until thre is an app, droplet or script that can introduce random variations (mutations, if you will…) into the watermark, the best defence is to introduce separately made (via filters) small variations in each image’s watermark, which means more manual labor (or mouse clicks), for the time being.

Ah Bruce, that’s just me — sorry if I was being unclear.

Before subscribing to Digimarc I would watermark my images in Photoshop. I had created what we used to call a “Droplet” (is it still called that, or am I really old? — basically a script created within Photoshop). With the Droplet file saved, I could automate application of watermarks on a number of images at a time if I chose to do so. I could, for example, “drop” the saved Droplet file on top of a folder full of images and Photoshop would add the watermark to each image automatically. I would feel productive and competent!

Given the recent news, I would no longer advise using the same artwork for a watermark across the board. Instead, you could create a watermark in an individual image file and then use Filter > Distort to slightly mangle it so the watermark-destroying algorithm is confused. Or even slightly mangle one or two of the letters. An inconsistent application of any of the Distort filters should do the trick. I would try any of the following to start: Ocean Ripple, Pinch, Ripple, Shear, Spherize, Twirl, Wave or ZigZag.

I know some artists who prefer to create their watermark artwork in Illustrator and then bring it into Photoshop to apply it over the image. They feel they have more control by starting in a vector-based program, and like the fact they can import it as a “smart object". Of course, Illustrator also has all the filters we would need to distort, or it could be distorted in Photoshop once it’s brought in. I’ll confess, if I wasn’t using Digimarc, I would probably still create my watermarks only using Photoshop, just to simplify the process as much as possible.

Hope I’ve understood the question; please let me know if I haven’t. It’s been a long week.

Can you indicate where we might find specific information on this statement:  "as well as use the Photoshop or Illustrator filters (depending on where you create your watermark) to uniquely warp or tweak each one."

Pardon my lack of insight into this issue :)
