What does the efficiency parametter mean?

[jorari71]

Hi again...I've been search what does the efficiency parametter mean and I haven't found anything...

 

Can anyone explain me about this parametters:

a).-Usual values.

b).-Is there any goal to reach?

c).-The higher the better?

 

I've noticed that when I don't have mirrors or something like this the efficiency starts higher...But the target is not to reach high efficiency isn't it?

 

Thank you.

The higher the Efficiency number, the fewer passes the scene will take to clear up. Complex interior scenes will be less efficient. Many factors can affect efficiency.

Thank you very much...

 

But...Do you have an usual or a normal value from which you can say:"this goes very well..." or where you can say: "this will never be cleared up...". I know it depends on the scene and the materials set up but maybe something like a guide or a few examples.

 

Could it be possible?

 

Thank you again.
