Exhibitions are the very vehicle through which art is shared with the world, presenting art in a hybrid public private space, and enabling a dissemination of ideas through those that visit it. An exhibition enables art to be juxtaposed and contextualised thereby also promoting new thoughts that may not have originated with its original making, but now form through the ideas and minds of people who experience it. The very practice of exhibiting art has a long and fascinating history which is in many ways as relevant to how contemporary art has unfolded. Historically exhibitions have questioned the very nature of art, igniting debate on what art is. Perhaps one of the earliest and most well-known exhibitions to question and protest the process of selection in the exhibition format was in the Salon des Refusés of 1863, which displayed those artworks rejected for the official Salon in the Palais d'Industrie. The impressionist artists also were able to make their mark by staging art exhibitions outside of the mainstream art institutions, thereby triggering a re-thinking of what art can be. By following exhibition history, a collector or curator (or other art enthusiast) can begin to form a more in-depth understanding of an artist's practice and the gallery's programme. Many galleries now see their spaces as being absolutely necessary to the need for their artists to exhibit their art and share their ideas, and to this end many museum quality shows take place in galleries today. Some galleries also are beginning to invest in online art exhibitions, and where relevant Ocula works with these galleries to drive attention to such exhibitions too. There is no better way to experience artwork than in the space the artist selects to show the work in, but where doing so is an impossibility, Ocula provides a possible alternative.
