We all usually can very quickly tell the 'posed' photos from the 'spontaneous' ones. 

Many times photos taken by amateur photographers burst out with freshness and originality.

The authenticity makes them a lot more interesting.

And this why Getty Images is encouraging everybody to present their photos to them.

First step is create a flickr account and then submit a portfolio to Getty Images. If found suitable, they will offer to present you pictures on their website where they may be bought by agencies and individuals. 

This will be a great way of funding your canvas prints and also getting recognized within community.
