>>76643 Difference between F8 and F2 is 4 stops.
HEres the shot he sent me from the dominican republic, ITs on a sunny day, Aka brightest you will probably ever get for IR.
F9 5 seconds, ISO 100
Difference between F9 and F1.8 say is roughly 5 stops of light, Difference between ISO 100 and 1600 is another 4 stops So 9 stop difference to get the exact exposure at ISO 1600 F1.8, 1/100th of a second (If i calculated that right)
So the picture is underexposed probably about 4 stops, Go back 4 stops and you now have 1/8th of a second...
