In which situations should I use my circular polarizing filter? I received a circular polarizing filter as a gift, but I have a hard time determining when I should be using it I've done river shots with some success, but other than that, it doesn't seem to do much beyond reducing the amount of light
filters - Why dont circular polarizers reduce light transmission by . . . 8 I assume that an ideal circular polarizing filter should cut light transmission by exactly half – i e , 1 stop – because every photon has (on average, with respect to a filter) either one of two circular polarities ("right" or "left) Yet "standard" circular polarizing filters cut light transmission by 1 5-2 5 stops
What is this triangle indicator on my circular polarizing filter? Many polarizing filters have a marking like this — either a triangle or a dot or something You'll get maximum effect if you align the camera so you're pointing in a direction roughly perpendicular to the sun in the sky and the mark is pointed at the sun This doesn't need to be exact, but it's an easy starting point Of course, with through-the-lens viewfinders (optical or electronic), you
Why do 3D platformers review so poorly and why are they so polarizing . . . I have noticed over the last few years that 3D platformers (excluding Mario games) often get reviewed poorly and receive much lower scores than they deserve They receive the most polarizing reviews of any genre I have seen Most reviewers either love them or HATE them For example, the
How do circular polarizing filters work and how are they made? 2 "Circular" polarizing filters allow the partial removing of non specular reflections like glass, water or snow reflections But what does circular mean? Does it mean that only the circular polarized light goes through or at the opposite, only the circular polarized light is stopped? Last, how is the coating made?
Is it wise to use polarizing filters with wide-angle lenses? 18 I've been looking into whether to use a regular UV or polarizing filter for a 16mm wide-angle lens and have found that a large number of people believe that you should never use a polarizer with a wide-angle lens
Why do polarising filters only work in one direction? As an addendum; a linear polarizer selects a (linear) polarization state by blocking all others Circularly polarized light, on average, contains equal parts of all polarization angles So no matter what, the linear polarizer will always take out (about) 50% of the light If the source is unpolarized, like daylight, the waveplate has no effect If it is polarized, it will convert the source
Are polarizers effective against reflections from glass? I have seen this question asked here How do I get rid of reflections on vertical glass fronts? I wonder if the same polarizer filters we use for making the underwater look clear instead of the sky
