What is a camera shutter? It is a small device located behind the lens of the camera and is responsible for controlling the amount of light that enters the camera and falls on the sensor. When you press the shutter button, you can open the shutter and let in sunlight or artificial lighting for capturing your image.
When you are using the shutter to capture motion or speed, then the length of time that the shutter is open also affects your image. The amount of time that the shutter remains open is called shutter speed or exposure time.
What is Shutter Speed? The shutter is present in every camera you can find. Shutter speed is part of the photography exposure triangle and works in harmony along with the aperture and ISO. With these three elements, you can control the amount of brightness you want to be present in a photograph, which is called exposure.
Shutter speed assignment
Compare the following shutter speeds and how they affect motion in your pictures *we are focusing on motion as shutter speed also effects exposure 1" (need tripod) 1/30 1/60 1/250 1/500 (or faster - must totally freeze the motion in this picture)
Think of some kind of motion:
playing catch
dropping an object
spinning pinwheel
jogging
etc
Then take photos at the shutter speeds above to compare how motion is affected in these activities.
Create a Photoshop file to compare your pictures:
File > New
Set up your canvas to 6" tall x 24" wide
Crop your Photos to a 4" x 4" size (300 Resolution)
Copy them to the New Canvas
Leave a 1" margin on all 4 sides and .5" between photos
Add text under each photo to label the shutter speeds
Text tool is a capital T symbol on the left side of the screen
