(Please read my Part 1 post before attempting this exercise)
You've worked your way through the subjects of f/stops and shutter speeds in my last post. I said before that good photography is hard work. A solid understanding of the f/stop and shutter speed relationship will make your photo experience much easier.
To that end and to see if I was successful in my description of f/stops and shutter speeds, try working out these couple of examples. If you answer these problems correctly, then "you get it" and everything else should be a piece of cake. For these problems, I will assume the camera is set on manual mode. This means the camera's meter will make a suggestion regarding f/stop and shutter speed settings, but it is up to you to make the final determination.
Use the list of whole f/stops and shutter speeds shown in my Part 2 post.
1. You are shooting a picture and your meter suggests you set your f/stop at f/11 and your shutter speed at 1/60th of a second. However, the picture you are taking is a soccer player running down the field, and you want to stop the player as he kicks the ball. So you need a shutter speed that's faster than 1/60th. You decide 1/500th of a second is a better shutter speed choice. (BUT the total amount of light entering the camera MUST remain the same for a correct exposure.)
What f/stop would you need to select to allow the camera to use a shutter speed of 1/500th?
2. The camera's meter suggests using an f/stop of f/4 with a shutter speed of 1/1,000th of a second. But the picture is of a landscape scene and you want as much depth of field as possible. You elect to use an f/stop of f/16 for extreme depth of field. (BUT the total amount of light entering the camera MUST remain the same for a correct exposure.)
What shutter speed would you have to select to allow the use of f/16 while keeping the total incoming amount of light the same?
Do the math. I'll give you the answers at the beginning of my next post. Good luck.
