Chapter 2: The Lens

In chapter 2 of A Short Course in Digital Photography I learned a lot about the lens, and a lot that I didn't even know there was to know about the lens. I learned, which I had no idea about that the lens speed is completely different than the shutter speed, it shows the largest aperture to which the lens diagram can be open. When a lens is faster it is able to open to a wider aperture, allowing more light in, which makes complete sense to me. The shutter speed clearness and exposure all depends on the amount of light that can be let in, with a bigger lens you could capture faster objects with still having the right amount of light.

I also learned how there are different lenses to use for different situations. Such as a long lens makes a smaller depth of field. Then a medium lens is useful for portraits because the photographer can be far away from the subject and still fit the image to the frame, then short lenses can get great depth of fields. I found it quite shocking as well that there were so many different lenses, including Macro, zoom, fisheye and so many more! I found learning about the distortions that could be created and the right lens for the right subject to be so important when taking a picture.
