Polarising Filters

[mattyb240]

Sorry I am a newbie, I have read the stickies, however I am just curious about peoples experience with CPL's, I have only ever had a basic one on my kit lens, whilst it worked pretty well, I think it gives a slight colour cast?

I have been looking at the Hoya range and am wondering if it is worth paying the £40+ for a Pro 1? As opposed to their basic £20?

It sounds so silly after buying a new lens, that obviously you should get the best you can afford, but just wondering about peoples real world experiences?

I have two Hoya Pro1 CPLs and they work great and are absolutely worth the money, especially if you do landscape work. I was a bit skeptical at first since I had purchased a cheap CPL and didn't really see the effect. After mounting the Hoya on my camera and going outside, I could instantly see the difference after one rotation. I was definitely hooked. Just make sure you get the Multi-coated/layered CPL. A bit more expensive, but worth it.

As for the color cast, CPLs act as a 1-1+2/3 ND filter, so you have to take that into account. Also, since CPLs cut glare/reflections, you will probably see a difference in color saturation (but not a color cast). The only thing I can think is that the CPL you purchased might not be color neutral. Just my guess.

Definitely spend more for quality. Your analysis is correct: why filter light going into a superb lens with distorted glass. B+W filters sold by B&H and others are also an excellent choice at a good price.

CH is correct about quality, argyle (amongst others) pointed me to the B+W MRC F-Pro CPL with the Kaesemann glass and I am very pleased with that choice (I have since replaced all my UV filters with B+Ws) the quality and craftsmanship shows in the build of it.

Traces makes another good point. Make sure whatever the quality brand you choose that it is a multi-coated version.

when using plagiarizers should I set exposure compensation +1? or no?

No. Basically the camera sees a darker scene and takes that into account when setting exposure.

Unless you are doing manual exposure! Then you have to take into account the loss of light due to the polarizer.

You did mean "polarizer", correct? For a minute there, I thought that you might have been referring to our gaffe-prone Vice President. :D

As far as exposure compensation goes, just keep an eye on your histogram. When necessary, add exposure compensation in order to expose to the right. If you haven't done so, I'd suggest setting your histogram to 'RGB'.
