Photography Club – Aperture

Last week we had another installment of our photography club. We learned about aperture. Aperture is how much light the lens allows. It works in conjunction with shutter speed, which determines how long the light is allowed to enter. It’s pretty straight forward, except that the smaller the f-stop (the scale of measurement that is used for aperture) the more light that is allowed in the lens. This is a very simplified definition of aperture.


My pre-digital textbook discussed depth of field along with aperture. Depth of field is the range in focus. Pictures that have the foreground, the background or both out of focus have a shorter depth of field. On the film camera in the book, it was very clear the relationship between aperture and depth of field. I was having trouble translating it to the digital camera. Fortunately, we had a guest “speaker” to our photography club. Our good friend, Mary, came to visit with us. She’s an awesome photographer and gave us some instruction on photography and my kiddos new camera. As far as I understand, depth of field is defined by aperture. Now I just need a little hands-on experimenting to completely get my head around it :) I’ll post pictures after we have another field trip!
