Shutter Speed And Aperture

Materials:

• Camera 
• Tripod

Shutter Speed

The average range of shutter speeds on cameras is between 6" through to 1/4000. 

• 6" means 6 seconds. This symbol " represents seconds.
• 1/4000 means 1 4000th of a second. 

Slow Shutter Speed

• 6" is a very slow shutter speed. A slow shutter speed lets in a lot of light to the photo. It is better to use a tripod when using a slow shutter speed as it will capture a blurred effect of a object in motion. 
• Anything less than 1/60 pictures work better with a tripod. A tripod will keep the camera in the same place which will help to capture a blurred effect of a object in motion. 

All these pictures were taken using a slow shutter speed - 1 second. 

• For these pictures I used long sparklers with the help of my brother.  

Fast Shutter Speed

• 1/4000 is a very fast shutter speed. A fast shutter speed lets a little amount of light into the photo. A faster shutter speed is used when you want to capture something dozen exactly in the moment. 
• It is usually the faster end of shutter speed which is used more frequently. 

Aperture

The range of aperture f1.8 to f22. 

• f1.8 is the widest aperture.
• f22 is the smallest aperture.

Wide Aperture 

• f1.8 or any low numbered aperture will be wide aperture. Wide Aperture means it will let in more light and shallowing the depth of field. Which means only the foreground of the picture will be in focus anything else with be out of focus so blurry. 

Small Aperture

• f22 or any high numbered aperture will be small aperture. Small aperture means it lets in very little amount of light. It also means none of the image will be blurry or out of focus. Both the foreground and the background will be visible and all in equal focus, but less light will enter into the camera. As less light will be let in due to the small aperture you will need to emend this out by slowing down the shutter speed to balance and compensate for the lack of light.
