I’ve learned a lot about my Nikon SLR over the past couple months, but I know I’ve just begun to explore the vast world of photography. So when a group of blogging friends decided to do an online photography class, I signed up too.
The first lesson is about Aperture. Aperture determines how much of the photo is in focus and refers to the size of the f/stop or lens. My lens allows me to go from 1.8 to 22, which gives me a great range to work with. A low f/stop – example 1.8 – means that the lens is wide open and allows more light in. This also means that less of the image will be in focus because so much light is coming in. The higher the f/stop – example 22 – the less light is let in because the lens is more closed. This also means that more of the whole picture will be in focus.
I’m already pretty familiar with the aperture settings on my camera, but I still had fun taking photos to demonstrate aperture in action. Here I took 3 photos of this carnation in a vase. I shot in manual mode, meaning I had to adjust the aperture and shutter speed.
This first photo has a very low f/stop – 1.8.
It let in a lot of light, so I had to up the shutter speed so it wouldn’t wash out the photo.
You can see how the flower is in focus, but the background is blurred.
This next photo has an f-stop of 7.1
The background is not as blurred as the lower aperture.
This is a higher aperture – f-stop 13.
See how the background is more in focus?
And that, my friends, is an example of how Aperture in photography works!
Does your camera have an aperture setting? Have you played around with it?
