Greetings, My wife and I are in Alaska visiting our son. I have been taking pictures, I am trying to be discriminating in my picture taking. I'm have taken some pictures of Mt Mckinley and the other peaks from Talkeetna. There is some haze near the mountains, but for this time of year, it's really pretty good. I am a little concerned about not being able to see the peaks as clear as I want to once downloaded. I am able to do okay with Lightroom. I am wondering if picking up a polorized filter would help. We're heading down to Seward tomorrow and there is a camera shop along the way in Anchorage that has one, but it is kind of pricey. I am willing to do it if it will help. I have no experience with this type of filter and was looking for some advice. Thank you in advance for your help, Ric

It's one of the few filters which can be worthwhile with digital, It should help although it may not completely eliminate the haze. Be sure to get a circular polariser not a linear, linear is said to upset the AF. Good polarisers are expensive. I just checked B&H site for a 67mm circular Polarising filter their prices range from $34 to over $250 with what I would call good ones in the $150-180 range. If you have the opportunity try a couple of different makes. Look for a window with reflections and focus on that, with a good polariser the reflections should disappear when you rotate the filter. I tried about 6 when I got mine and the difference between makes is astounding. I think mine is a B+W. Having said all that sometimes it is nice to see the diminishing haze effect as successive ranges of hills or mountains recede into the mist. It's an effect I try to get sometimes. If done right it can add depth to an image, it can help to have a nice foreground.

Thank you, Robert. I will keep this in mind when I go into town today. Ric

Just keep in mind Ric, that a polarizer is really a special version of a neutral density filter. You will lose some light intensity when you apply it. Having spent quite a bit of time in Alaska, I can tell you that unless you have a fast lens and a noise-free high ISO camera, you can miss (or foul up) shots if you have a polarizer in place. Just keep that in mind. - EdM

Good point Ed, the filter may be marked with it's exposure rating, I think X2 is normal? So turn the Exposure comp up by +1 stop and watch the histogram. As an aside if you use two ND filters they can act as a variable ND filter by rotating just one of the filters.

As a P.S., I use my circular polarizer (a Tiffen) whenever I can. It's great for fall foliage shots, because it eliminates a good portion of the reflected sunlight from the leaves and consequently lets more of the colors be seen. Same with the sky colors. There were times shooting the Kodiak brown bears when the conditions would have permitted, I wished I had one mounted, but the speed of the action wouldn't let me stop shooting and screw one in place. I'd definetly get one even if you don't use it on your Alaska trip. Post some photos when you get back, and good luck and good shooting. - EdM

Since the filter is attached to the lens, wouldn't the camera's exposure system compensate for this x1 or x2? Or do you just know it may compensate too much and you want to add some exposure?

In theory, but I find it's often necessary to compensate up to 1 stop. I would expect this to be one of those situations, ALWAYS check the histogram, at least for the first few exposures and as the light changes. I generally take an exposure of grass or even my hand when I start a photo session to check the exposure.

To me it's the greatest invention of the DSLR, apart from free film of course!
