Sometimes polarizers make a Huge difference

These shots were both taken within a few minutes of each other. The first shot has no polarizer filter and the second has a b+w Circular Polarizer E at full polarization, 90 degrees dialed away from the sun. The reason I wanted to share this is because I had always been curious about how much light it would remove and thought others may benefit as well. These images are straight raw from the camera and have had no post processing done to them. Both shots were taken at 300mm F10 iso100 first shot 1/40 a second shot the same only 1/10 of a second, so you loose 1/30 of a second using a circular polarizer. These are both shot in natural light no flash.

Good comparison. Does have a marked effect. Your shutter speed loss seems to correlate well with the 2 stop light loss I'd heard for polarisers.

Interesting comparison, yes you typically loose about 2 stops.

Probably worth using if shooting by traditional methods with a tripod and mirror lockup, if working handheld one probably can't afford the light loss.

Would be worth trying this with very metallic and reflective species like Demoiselles and some of the beetles.

good point lester, in this instance I was not doing hand held because I was using a 300mm, which would be close to impossible to handhold. Im not sure how this would work with a flash though, I guess if you can stay at 1/200 and turn up the flash then it may work. Another option would be to use a higher iso to compensate shutter speed, I was shooting at 100.

nice comparison wes.
I use them for landscape,and often thought about using them for macro.

I tried a Polarizer with flash once, the problem is getting the angle right. As far as I can tell you need to be a maths wizard, a clairvoyant, or an incredibly fortunate individual.

Great comparison Wes.
