Your effectively stealing straight from the photographer, rather than a big faceless company(thats budgeted for it), just seems morally worse.
No theft is involved, because no-one is being deprived of a resource. Back to this issue later - I'm off
One of the reasons that I believe that copyright enforcement isn't anywhere near as clear cut is because of the amount of music that goes around. Artists seem to think they are being cheated should anyone want to listen to their music without following strict instructions to do so - it is an affront to art, it is an affront to goodwill.
There is no way to stop a person using music, an image and unless they are passing it off as their own or using it to make money whilst depriving the artist then it should be taken
Music is largely recycled, and no photographer would like it if architects, car designers, models and people took the same attitude as they do with regards to their photos. What if you had to seek a landowners permission before photographing anything on their land, what about the council or even the government?
Art is the depiction of beauty, and no-one can or should own beauty. If you're a photographer and wish to stamp on the creative right of others to appreciate your material in the way they consider appropriate, you are a scrooge and your heart isn't in it.
As long as no-one is making money from your efforts and they aren't passing it off as their own, then you should WANT to see your work shared.
