I'm proud of myself for that. On another note though, I love the photo for the assignment Chris! Great job. :D I learned f/ on my own from descrete hints on this show. I’m proud of myself for that.

My bad!!! WHOOPS!!! hey sorry about that - I just realized that yeah, the same thing (factor) can work for the diameter as well… My bad!!!

Correct me if I'm wrong here. if each stop is supposed to double/half the area, shouldn’t the number refer to the *radius* of the aperture instead? cos if it were the diameter, you need to multiply by a factor of 2*(square root of 2) in order to double the area for each stop… ie. you should have the sequence f/1, f/2.8, f/8, f/22 instead… Correct me if I’m wrong here.
