Aperture

Today I went out to play with my new lens a little bit more and I had a fun idea. One of the interesting features of my new lens is the fact that it has a much wider aperture than previous lenses i've used. For those of you who understand what aperture is, great. For those of you who aren't too sure what it means, the aperture is basically how much light is allowed into the camera based on how wide the leaves in the lens can open. Obviously, the wider the aperture, the more light is let in, but the aperture also has a huge effect on focus as illustrated below. when the aperture is all the way open, the camera will only focus on a very small predetermined point and will throw the rest of the scene out of focus. As the aperture becomes smaller, it has to balance the focus more evenly throughout the entire scene. Below is an animation showing the effect of the aperture value (or f-stop) gradually moving from wide open (f1.8) to the smallest possible opening for this lens (f22). Again, wide open = blurry background; smallest opening = clearer background. Interestingly, I made this animation directly in photoshop which is also a plus because I had the opportunity to learn even more about the tools necessary for me to do my job efficiently. Let me know what you think!
