Please anyone help me,
B&W 90(25) : Filter factor is 3 = 2 stops (25 red should be 3 stops isn't it? , but B&W red 25 just 2 stop???)
B&W 91(29) : Filter factor is 8 = 3 stops ( They said a bit high contrast)
I cannot decide which one I should go for.. Mostly I'm landscape and architectural photography. I already have Yellow Orange B&W 40(16): Filter factor is 4 = 2 stops...
I read all descriptions of both, but I've never used them at the same time, I would like to know which one is more useful in general. I mean, what's typical "Red" filter should be .. I still need rich gray tone and detail in shadow as well.
Please me,
Ten.
