What does Aperture do? Photography for Beginners Series
In this session I talk you through the details of aperture. We are going to nail this concept over the next two episodes I promise! Understanding aperture is a piece of cake and I will prove it to you. So what does aperture do?
Below is a summary of what I cover in the show;
- One way of controlling the light entering your camera is to change the size of your aperture (the opening in your lens).
- Aperture size is referred to in f-stops.
- The wider the aperture, the smaller the f-number. The narrower the aperture, the bigger the f-number. E.g. f/1.8 is very wide and f/16 is very narrow (annoying I know!)
A visual always helps too…
- Aperture size controls the amount of light entering, however, it also does something else that is very important. It controls your depth of field.
- Depth of field is the distance of sharp focus you have in your image.
- The wider the aperture, the shallower the depth of field. The narrower the aperture, the deeper the depth of field.
And here are the lego images I mention on the podcast;
- Many lifestyle portrait photographers like myself shoot a lot of portraits with a wide aperture so that we get a shallow depth of field. A sharp subject (person) and an out of focus background.
Remember this is just a short summary of a much more detailed podcast episode. In Episode 3 we are sticking with aperture and fleshing it all out a little bit more.
TEA BREAK TASK
Switch your camera to manual mode (M). Find out how to change the aperture on your particular camera by looking up ‘aperture’ in your camera manual. Alternatively, type the question with your camera model into google.
Once you know how to change your aperture I want you to simply practice changing it. Open is wide and narrow it down paying close attention to the f-numbers and where you see them changing on your particular camera.
