Jessica Rodriguez-About five times a semester, the Junior Fellows incorporate an educational program into their meetings. These can range from discussions of film, software usage, to architecture–basically, a topic that has cultural or occupational value. Occasionally, we bring in experts on these topics, but sometimes we lead the program ourselves.
A few weeks ago, I had the pleasure of presenting a program on photography to the rest of the Junior Fellows. I am a self-taught photographer who took up photography and graphic design as a hobby at the age of 13.
I put together a PowerPoint presentation covering the basics of shutter speed, aperture, and ISO.
I began by demonstrating the importance of shutter speed–the amount of time that the camera’s shutter is open. Knowing how to adjust shutter speed is particularly important when an object is fast moving, or when photographing in a low light situation.
Additionally, I went over ISO, which measures the camera’s sensitivity to light. A lower ISO is recommended when the lighting permits, but in low-light situations a higher ISO may be required, as in the pictures below. Unfortunately, the higher ISO may result in increased granularity.
We also covered aperture, which also affects the amount of light permitted (and the focus of the photograph), as the photographs below suggest:
On a more basic level, we also discussed the importance of deciding in advance the main subject of the photograph and–literally–focusing on that.
Then, we just let the JFs play with their cameras and they produced some nice photos!
And this one…
