What filters does everybody use and which one is your favorite? How much did they cost?
I recently purchased a polarizer and spent 225 on it. I thought that was kinda high. Anybody know the difference between the 225 dollar filter and the 30 dollar filter?
I would guess every serious photographer owns and uses a polarizing filter.
In the days of black/white film, a yellow/orange/red filter was very useful to darken skies.
For the specific purpose of using a long exposure to blur moving water, a ND filter is useful.
Cameras with reflex mirrors generally need circular polarizers, in order not to interfere with the autofocus and metering systems. Cameras without mirrors only need linear polarizers. A circular polarizer contains a linear polarized plus another optical element and is considerably more expensive.
