Filters I like to photograph sunrises, I have a skylight filter on my lens, and I use a polarizing filter on top of that (Kodak made by Tiffen screw type). For some reason, I have trouble getting them apart. I don't tighten then very much, but it can be a real problem to get them apart. I live in Florida usually warm here but lately high 30's low 40's in the morning. Could it be the temp. that's causing the problem? It's now 3 P.M.(about 60 degrees) and I just unscrewed it without any trouble. Is there a way around this? Thanks

This is a common problem. Why? I don't know! The solution? Wrap an elastic band around the polarizer and that will give you the grip you need to loosen it.

Raywino gives one of the common home remedy methods to get them apart. There are similar, inexpensive tools for this that will grip the filter ring with rubber or neoprene and give you some leverage. You can find them at nearly any large camera store. What causes it? Temperature and humidity have little to do with it most of the time. A few manufacturers, including Tiffen and Hoya use aluminum rings on their filters. If aluminum is screwed into polycarbonate threads on a lens ring, it's usually not too hard to remove. If it's screwed into metal threads, they are notorious for binding up. The sturdiest and easiest to remove are brass ring filters. B+W and Heliopan both use brass rings for this reason. If you use brass ringed filters on polycarbonate lens threads, be careful with them. They are stiffer than aluminum and a polycarbonate lens ring may give first if you bang the front of the lens hard enough into something. On metal (even aluminum) lens barrels this is not a problem, although banging a lens into anything can damage the lens by shifting its elements, even if the filter ring and lens threads survive.
