Apart from offering a certain number of printed photos and some in high resolution on CD which will allow the client to print as chosen, I also want to offer a majority of the edited photos in much lower resolution for web use like Facebook, Flickr etc. etc.
Would it make sense to watermark/sign these lower res imageg or would you not ever watermark/sign the images provided to the client.
Given the market here, the client is more likely than not to disregard everything and try to print off these low resolution images so I was thinking of using a signature at a selected corner to deter from printing and also a sort of advertisement. Is there a good low resolution but enough for web use that would print rather bad?
