Watermarks, some photographers love them because they protect their images. Some hate them because they are an eyesore and can be removed by anyone skilled in Photoshop. In August 2017, researchers from Google created an algorithm that can remove watermarks from images within seconds. What does this mean for for photographers and stock photo companies? Let’s find out.
What Are Watermarks?
Simply stated, it is a logo or name that’s overlaid onto an image. Below, I’ve included an example using one of my images.
The purpose of a watermark is to prevent online image theft and to show ownership or copyright. Although not foolproof, it does discourage some people from taking images, removing the watermark, and claiming them as their own. They also serve as a form of online advertising. For example, if someone notices one of your images on a photo sharing site they will know who created the image if they wish to purchase it or view your other images.
How Google Removes Watermarks
Because a watermark is applied in a very consistent manner to each image, the Google researchers were able to write an algorithm to detect their placement. Next, they automated the removal process.
The video below explains the process and shows the speed at which the computer algorithm can remove the watermarks.
How Will This Impact Photographers & Stock Companies?
Fortunately for photographers and stock agencies, Google also discovered how to make a watermark more difficult to remove. By adding just a slight, random warping to each watermark, the algorithm can no longer completely remove it. As seen in the above video, one would still have to edit each image by hand to completely remove each watermark.
