Day 5 - Understanding Aperture also known as f/stop
Here's an illustration that shows how f/stops effect the shutter. This might help to give you a visual as I describe the effects in greater detail below.
Lowering your f/stop
In this example of baby Eli, you can see that my depth of field is much tighter, not all of him is in focus.
Raising your f/stop
In this example, I needed more depth of field to get these brothers and the background in focus.
How does aperture effect shutter speed?
- Using a low f/stop means that MORE light is coming into the camera lens, therefore the shutter doesn’t stay open as long to make the correct exposure of your picture.
- Using a high f/stop means that LESS light is coming into the camera lens, therefore the shutter will need to stay open a little longer to get the correct exposure of your picture.
Today’s Takeaway and To Do’s:
- Look over the smaller to larger f/stops and get familiar with how they work by re-reading this post until it sinks in and makes sense… not to worry, it will click.
- Look in your manual at how to change the f/stops in your camera… get familiar with how it works.
- Try something fun: Place two objects side by side (two chairs for example), Turn your camera dial to A (Nikon) or AV (canon), now turn your f/stop to it’s smallest number (your smallest number may be 3.5 depending on the lens that is on your camera).
- Start shooting bumping your f/stop up each time. What did you notice happened?
- Now do it again in the same order. You can even try another object such as a toy or a book. See you tomorrow. Great job today! You are getting this!
See you tomorrow!
