Aperture Review

Remember:

     Aperture refers to the size of the HOLE.

     A large aperture makes items close in focus...and things far away blurry.

This was taken at f-3.2

     F-Stop refers to the f-number 
 

This was taken at f-9

     A large F-Stop number will make things far away very clear and in focus
.



      So, you have to check the question to see if it is asking about the f-stop number or the APERTURE.


















   Today,

       1.  Fix the questions that you got wrong on the Aperture Worksheet from yesterday.

       2.  Go to http://www.nga.gov/kids/zone/photoop.htm   Try making a moving object blurry, while the background is in focus.  Try changing the aperture and shutter speed to make the photos look clear in the background, or blurry in the background.

       3.  Visit these links:

        4.  Don't forget that MACRO MODE (50+) photos are due on Monday.  No Photos = Bookwork.
