Re: Understanding Exposure
Glen, I am very familiar with the relationship between F Stop, shutter speed, ISO and DOF. Now, distance from subject and how it affects DOF I have yet to fully comprehend. I know the closer I am to the subject and the wider the aperture, the less the DOF. I will worry about that at another time.
I was thinking in the shower today...I get so many things stuck in my head...and I was realizing...I was pretty happy with the sunny 16 rule as long as the sun was behind my back. As soon as the sun was in front of me, I needed to add flash.
And I know this has been said before on this thread...sunny 16 is a starting place. I could have used any of the equivalent exposures if I wanted to affect the DOF.
16/100 = 32/50 = 11/200 = 8/400.....right?
I need to commit the "full stops" to memory. I believe someone on this thread listed full stops.
