One of the commonly used ways to protect your photos against stealing is putting a watermark on them. However, I'm not really happy about doing so for several reasons:
- If you put watermark near the border then stealing an image is still a very easy thing as it is just enough to crop the watermark out. And so many photographers put it right there.
- If you put a watermark in the area with many details or in a place that is important to the image perception you actually make the image weaker. What you can do instead is to put a watermark in a non-important part of the image (eg. over the sky or road) but in such a case it might turn out that it is still very easy to remove it by cloning or using a content-aware feature in Photoshop.
- It is distracting. If I make a photo I often want viewers to focus on a certain part of the image or lead their eyes into something in the picture. By putting a watermark I can ruin that because there is a great chance that they will first look at the watermark and only after that at the picture itself.
- One of the options is to make sure watermark fits well into the image (in a sense that it becomes part of it) but to be honest I haven't seen it executed well up to now.
