Why is watermarking useless? Depending on the invasiveness of the watermark it can be quite useful.
The issue is not just one of someone making print from your image, but also that image being used on the web as an illustration of some sort. This is an issue that troubles me.
I would love it if future EXIF data standards had an area that could not be modified at all. Yet searchable via Google, so we could have a fighting chance against those that take and use our images (no matter how low-res) for their personal use. I know that there are issues with this idea. But at the same time IMO it is not beyond the realm of possibility also.
So do we just not want anyone have a photo of ours for personal use, or do we not want someone using a photo for commercial use and profit? Big difference to me.
I doubt it would bother me is someone wanted to use an image of mine for "personal use", might even be flattered, but then what are the odds of even knowing about it. Of course I would never quit my day job and think I could make a living with photography. Many others do make a living through photography and their viewpoints would naturally be different than mine.
Hypothetically, and getting off topic slightly
If I were to notice an image of mine being used for an advertisement or some other "commercial use", I would at first be flattered, then maybe a little put out I was getting any credit for it. I never worried about that with film scans, I have the negatives and that is pretty good proof of ownership. So if someone was making out big time with work of mine, I would have recourse. With digital it may be harder to prove ownership if you needed to. While I doubt this would ever be an issue for me, it makes me wonder, if by shooting RAW files, you would not have a better chance of defending your work? RAW is sort of a "digital negative" and if you had the original RAW file, might that be all the proof one needs? I don't think you can convert a jpeg or tiff back to RAW? Another option (of proof of ownership) is the invisible watermarks like Digimark?
I really hate some of the huge watermarks that show up on photos, and the small low res ones make it hard to appreciate the photo.
