Are there also invisible watermarks on the images?
- bmelton 14y agoI'm not sure if you're asking whether or not there's information encoded in the image's metadata, or whether they're using some sort of additional watermark that appears when the image is downloaded or copied, ala this article[1]. If you're asking about metadata, I can say that on the Getty images I've used in the past (not for years though, so it's old data,) they were pretty diligent about ensuring Authorship information in the metadata. I can't remember whether or not there were any specific Getty attributions in there, like a link back to a page it could be purchased from, but in other comments here I see that they have a 'creative ID', which I didn't know about, so it's possible I just glossed over it. If you're asking about the second, I believe the answer is no, but I say so without having tried it, even cursorily. http://blog.makezine.com/2009/02/16/invisible-watermark/ http://blog.makezine.com/2009/02/16/invisible-watermark/
- jmilloy 14y agoI assumed he was asking about a third option - imperceptible digital watermarking.
- bmelton 14y agoIs that not the same as the second? The second method can be generally be detected programatically, but is invisible to the human eye. I was going to question the usefulness of an invisible watermark, as you could otherwise just compare a hash of the image, but I suppose an invisible watermark would likely persist through re-editing / resizing?
- ig1 14y agoGetty used to use Digimarc's steganographic watermarking technology, but I don't know if they still do.
- k33l0r 14y agoApparently not, just tried to unsuccessfully read the Digimarc watermark off a random Getty photo in Photoshop…
- idspispopd 14y agoThe files have metadata to help find the source.(Digimarc used to be implemented also.) The meta data is easily removed as is editing out the watermark. However those aren't ever going to be paying customers anyway. When you license stock, you get more than just the high resolution file, but also 1. exclusivity if you've requested it and the necessary waivers to use the image in the way intended. For example, a night time shot of the Eiffel Tower requires a waiver, as the light show is subject to copyright. (Believe it or not!) While a day shot won't require a waiver. Not having a legitimate waiver is asking for a damages case by the owner, those depicted or other entity. This is covered in most countries via copyright & publicity laws.
