The popular smartphone application Instagram (照片分享) has changed the way we look at photography, even our world. The photo-worthy moments we share serve as an important function in cultivating the photographic artistic eye.

Instagram has got people to start noticing the art in their everyday life. It has also allowed us to share the artful moments in our lives with others. Clearly, making people focus on beautiful moments in their lives and how to share them is a positive takeaway from Instagram.

Not only has Instagram changed the way we look at things around us, but it has also changed the way people view professional photography. Instagram has turned everyone with a smartphone into an artist. Opening up art to the general community is a groundbreaking (创新的) aspect of this application. Making artistic attempts accessible for everyone to discover their artistic talents and explore creatively is something that has made people find the beauty in the everyday. However, this accessibility has also created questioning around art and respect deserved by professional photography.

The art in a professional photograph versus an Instagram can sometimes be hard to notice at a quick glance. But photographs taken by true professional photographers hold something that Instagram’s can’t match in terms of photographic quality, or advanced compositional knowledge.

This is not to say Instagram is a lesser art. Aesthetic qualities of art are a personal matter and how good an artwork is depends on personal preferences. Good is a very arbitrary term in the art world. For example, I may find one photo more pleasing than another, but not everyone has to agree with me.

The point I am trying to make is that professional photography should not be lost, but instead approached with a new, enhanced level of respect and admiration—despite how accessible, common and fun Instagram now makes the taking and sharing of photos.
