Step 12Test Depth of Field
This is not mandatory, but I like to know what I got.
Place an accurate scale on a 60 degree angle and take a shot. You can measure your DoF. The bold numbers pictured are tenths of an inch. The lines are hundredths of an inch.
In a 30 60 90 right triangle, the short leg (depth) is one half the hypotenuse (the image). It looks to me that the in-focus portion is about 6 or 7 hundredths of an inch. That makes my DoF about 3 to 3.5 hundredths of an inch (.03 in) or .89mm. Wow! Almost a whole mm!
