Hi,
(pardon about my poor English...)
Please, I would like to know if it's correct to think this way:
If gray card (Zone V) is 18%, so:
-Zone IV is 9%
-Zone III is 4.5%
-Zone II is 2.25%
and
Zone I is 1.12%
So, the minimum that the emulsion sees is about 2,25%? (thinking in percentage)
or is better this way:
-Zone I is 1%
-Zone II is 2%
-Zone III is 4%
-Zone IV is 8%
and
-Zone (or gray card) is 16%?
(I read something about this new value of gray card at internet).
Thanks in advance.
Best regards from Brasil,
Abraham Metri
