Polarizer filter in B/W photography

[Alberto Bregani]

For example, have a look at Adorama's selection of 105mm polarisers. I just had a look and the Lee is about twice the price of B+W (or Sigma). Good luck!

Thank you all Ian, Dave, Brian, Greg, Rick
you are always a great source of advices

I use it when i want to give a kind of ... small stroke(?) to the negative...
usually in late spring and september ...around 4/6 pm when you have a good quality of light;
It helps me to separate tones in a useful way, giving composition a kind of 3d effect
Don't know why with water/ waterfalls i 've always used ND... never come to mind to use polarizer
Bah...

Do you think could it be useful stack a Polarizer and ND filter together?
tks

A point to remember is that a circular polarizer is not needed for large-format applications. These are used for small-format cameras that use various polarized means to direct scenery light to the meter sensors. The linear polarizers ("top" in B+W lingo) are much less expensive than the circular polarizers.

I don't think he means "circular" vs "linear'' as for the digital sensor sense but round vs square. As for ND filters, I never used them as the exposure times with large format is already slow enough. I use yellow, orange and other colors for B&W tone compensating with polarized filter often. You'll have to add up all that exposure compensation or meter the scene through the filter combo.

Maybe so. But circular polarizers are so ubiquitously required for small format that folks might not realize it isn't for what we do.
