My 'fast' 8x10 lenses are f5.6 and my 'fast' 35mm lenses are 1.4. The image I see with my 35mm cameras when composing is much brighter. How about you, what do you see with your equipment?
You can see the effect by just looking through the filter and then the only thing you have to do us directing the camera the same way and to mount the filter at same angular orientation. I do see a difficultiy in this, unless one establishes extreme movement where the angular position of the front standard is not really obvious.
People using a plain finder or rangefinder camera have as only means to look through the filter directly.
I'll second AgX's advice. Exposure compensation will involve a little guess work that will be worked out with experience, if not already.Alright, thank you.
When using my fixed lens rangefinder I look through the filter, find the best orientation, then mark the two components of the polarizer with a grease pencil then use that mark to line up the lens on the camera. My view camera lens are all 5.6 and 6.3, I use figure out the amount of polarizing from the ground glass.
If the groundglass is bright and even enough, you can usually figure it out by looking at the groundglass. With a wide lens, it helps to have a fresnel. Also be sure it’s dark under the darkcloth without too much light leakage, and let your eyes adjust, and you can see what’s happening even with the lens stopped down.
Thank you I use the BLACKJACKET from quietworks it completely eliminates light leakage. http://quietworks.com/FRAMES_FILES/WELCOME_BJ_FOCUSINGCLOTH.html
Seems linear polarizing is the way to go when needed.
Hi,
Will it be more difficult to visualize the effect of a polarizing filter on a view camera than a smaller format?
Thank you

IMO it's more difficult to see it, it's always more difficult to see anything in the view camera GG than in a convenient viewfinder of a SLR
But but you can always adjust well the cross-polarization in the GG, just look at the glares in the scene from sunlight to rotate the filter. As always Pol do nothing if illumination is not polarized, in an overcast sky Pol acts mostly as a Neutral Density filter taking 30% of the light. Direct sunlight is Polarized by the Earth's magnetic field, but an overcast sky destroys the light polarization.
Personally, sometimes I did something to adjust the polarization degree (angle to the top cross polarizarion), as I use a DSLR to meter I find the angle and I use the same in the view camera. Anyway you simply can compare what happens in the SLR/DSLR view finder (as you rotate filter) to see how the same looks in the GG, to learn better the effect.
With Velvia it darkens sky, preventing local overexposure. In general Velvia is saturated enough, but...
If you can't see the effect on the ground glass, the light you are trying to eliminate may be scattered. The ground glass of a veiw camera, of course, allows for much more detailed analysis of a scene than, for example, a SLR viewfinder. Those are usually suitable for snapshot type images.My view camera with a 5.6 lens yields a bright view. I'm wondering if a polarizing filter will be visible with rotating it.
Thank you.
