The artistic world is so big that it divides art galleries into a large number of categories. Normally, an art gallery focuses on a specific thing and it is taken care of by a curator who knows everything about that type of art. Most often, in art galleries one can find art from certain regions, from a specific medium, style of art that has one sole focus (political art can be an example). In this case, the majority of the art gallery pieces are for sale, but the gallery can preserve a certain collection if it wants. https://inesarenas.com/
In addition to this, most art galleries are open to the public and they allow people to enter and buy art if they want. In this case, lots of public galleries host openings and they advertise their presence in order to gain more audience. This helps young artists affirm themselves and it can even help them sell their work. Very often, galleries buy art from other artists in order to resell it later. There are also private art galleries which require a membership in order to offer access. And last but not least, from this top one shouldn’t leave out the private galleries that display only high-end art and host exclusivist guests.
Lots of galleries employ curators in order to deal with one type of art from a certain period or region. For instance, the most popular regions are those who deal with European, Australian, Chinese, Asian or African art. In some cases, the regional focus is not widely spread (for instance, a gallery can show just Peruvian textiles).
In other circumstances, the focus is broad, including lots of styles from a larger region of the globe. There are also cases when a gallery includes just the art that comes from a certain period in the history (contemporary art galleries in particular).
Most often, art galleries concentrate just on a single medium (oil painting, textiles, furniture, jewelry, sculpture, pottery or photography). This medium can belong to just a time zone or region, or it can come from a general group of works from the same medium. The art that is displayed here can be signed by a variety of artists, and it allows those who are passionate about that specific art to buy their favorite pieces.
Another type of art that can be found in a gallery is that which has a certain cultural focus. Whether it’s political, medium or historical, every piece of art has its own characteristics. For instance, a gallery can choose to show only comic art or pieces signed by Jewish artists, African refugees, etc. These are the galleries that are wide open to the audience and that want to encourage the education.
