I am very excited I came across this site. I am an artist and sometimes when I have a commission to do, I travel to the place and take lots of pics. This is very timely and expensive,lol. So I am trying to get clear on this site. Can I use the photos for a reference to the painting I am doing?
If I understand your question correctly, as long as you took the photos you can copy them anyway you like. If the photos were taken by someone else they belong to that person and they have the copyright, so you cannot 'copy' their work. Of course you might be able to get permission from the photographer if you sent them a message via the 'tools' box next to the image you want to copy. Hope that helps.
If I understood your question correctly, you intend to use your own photos as references for your paintings. If so, yes you are allowed to do so. Also, if you intend to submit any art piece (paintings, drawings, sketches, etc) please note that you will also have to fill in a Property Release document with a small photo of the reference photo/s. Hope this clarifies your question. :)
