"Ha, so she is. That mirror trick works really well - the light isn't harsh at all."

"On this one I doubled the f stop to f/11. With the new calculations, 98 mm are in focus; this does nearly double the area in focus, both in terms of calculations and in the actual picture. In the second picture, from the 30 to the 17 roughly is in focus as opposed to the earlier 5 cm, 13 are in focus. I'm only off by 1cm! Victory."

"So f=55, N=5.6, C= 0.04309 and U= 470. Plugging this into the formula gives: 35.2mm. Taking sqrt2 calculations into account, the answer should be 50 mm. Looking at the screen on the rightly sized window, between the 26 and 21 is in focus- this is 5 mm and fits the calculations rightly."

"The sensor is 23.7mm across. This means the circle of confusion is 1.5/825 times 23.7 which is .04309mm."

"I'm using 1.5 pixels as well. I sized my picture so it has 825 pixels, so I do 1.5/825 and then..."
