I took this photo as a teachable moment. In case you're wondering what this is, it's a lens filter. The first thing my uncle told me when he bought me my first camera was to put one of these on every single lens I ever get. 1.) They make your photos clearer. 2.) They protect your lenses. There have been numerous instances when an accident has happened, and each time these $15 filters saved me hundreds in replaces lenses.If you're a photographer or thinking about being one, mark my words: invest in a filter!
