So much valuable info. This is exactly what I have been looking for all over. How to set exposure with Log. Now question. The exposure has been set, from here do you simply overexpose by 2 stops since its needed to slog, so you would be shoot at f/4?
can you please explain the math behind the F-T stops and diaphragm correction in detail? 8.9-8.3=0.6 for this particular scene, right? but if a stop value is diaphragm dependent, and at a 8.9 diaphragm a full stop is either 2.5 down or 3.6 up, therefore 0.6 difference @8.9 is either 0.24 or 0.17 stops? also, for the same lens the markings on the cover say f/2.0 t2.3 or in pt 1 of the video f/2.8 t3.4 -- how do you calculate those 0.6 and 0.5?
This was sooo helpful. Thank you!
