Free things generate a greater audience than paid things. Unsplash – the free stock photography site – is no stranger to this rule of human nature. In fact, it was the foundation for their entire company.

Unsplash is a community where anyone can share high-resolution photos for anyone to use freely. It began as a Tumblr blog with ten photos we had leftover from a photoshoot… Those first ten photos have been seen 58 million times.
