I just got a Tiffen 3mm Streak Filter. There was an option between a 3mm or a 2mm, what is the different between the 2? I figured 3mm would give me the look i've been wanting but I am just curious about the different between the 2.
Im doing a scene where the main character is in the car & it is raining outside, rain drops rolling down the window & windshield. How can I get the reflection of the rain on the characters face?
