ISO is like the bucket size. how much water does it take to get a bucket ful.

Then to get the bucket full of water you use a water hose. How long you need the water to run (Shutter speed) is a function of how big the water hose is (f-Stop).

Keep in mind is water pressure is low (less brightness) you can get a bigger hose or wait longer to get your bucket full.

my hubby has been having trouble understanding this...it just made so much sense to him...a light bulb went off!!! thanks so much!
