Polarizer Filters

[Sergi Vilanova]

Hello everybody:

 

I don't know if this has been discussed before; if so, excuse me, but I haven't found it already.

 

Does anybody know which are the most evident and (more important) the most practical (in terms of use - results) diferences between the Standard Pola, the UltraPola and the True Pola?

 

I've used before the pola and the true pola, and the only reason I found to choose one or another was what I felt was right at that moment in that particular job.

But I wouldn't be able to explain why.

So, if anyone has incomes on that regard, i wold apretiate them a lot.

 

thank you

s.
