A polarized microwave emitter and a polarized microwave receiver face each other on a table. At first, the emitter and receiver are polarized in the same direction (up-down), and all the emitted signal gets received. When a metal comb in inserted between them, with the teeth pointed down, the signal is blocked. This is because the microwaves are polarized in the same direction that the teeth are pointing, creating small currents in the metal that reflect the microwaves backwards. When the comb teeth are turned horizontally, the signal passes through undisturbed.When the receiver is turned 90 degrees, no signal is received. However, when the comb is inserted at a 45 degree angle, some signal passes through. This is because light waves are made up of two perpendicular components that add up to form the polarization of the wave. When one component is knocked out, the wave changes polarization.

Fish and Turtle with Polarizer Lens Test from rgtaa rgtaa on Vimeo. Fish and Turtle with Polarizer lens HV20 auto everything uv lens POLARIZER lens I can see under the water and see the big FISH NOW! :) This is unedited footage without any POST stuff, no color correction or gamma ray stuff, just to show difference between with POLALIZER LENS and other clip before this one without the polarizer lens P.S. The sounds in background are not camcorder tape noise, just construction crew tearing up the Park to "improve it"! ;) Cast: rgtaa rgtaa

Short tutorial showing how to use polarizing filter in photography. First part is teoretical instructions, then there are some examples of use.

Photo#26,984,62,154,185,935 : There are still certain physical filters that I use and some that I am now shying away from in favour of Photoshop. Listen on for details, along with some real-world examples. In recent years, digital photography has done away with the necessity for some filters, such as daylight filters and warm-up filters etc as most colour correction is now taken care of much more easily by the White Balance feature on our cameras. Check out the Cokin filter systems here http://www.cokin.com/ or here http://www.cokin.co.uk. Here is the discussion I mentioned in which bksecret (Landon) raised some great tips for when using a Polarizer. http://www.martinbaileyphotography.com/forum/viewtopic.php?t=684 And here is the topic on protector filters, discussing whether we even need them, and whether or not you should buy the best, or go for the cheapest you can, as these are sometimes a throw away item. http://www.martinbaileyphotography.com/forum/viewtopic.php?t=677 I also mentioned using a PL filter to reduce the reflection in water in Podcast # 15. http://www.martinbaileyphotography.com/podcasts.php?dt=ti&ep=015#Ep015 Here's a link to the new Podcast "Light" page I mentioned at the end of this episode.

Shelton talks about using filters. Why they're still neccessary, and which ones make good starting points for those who've never used them.

Shelton talks about why you might consider an SLR over a compact camera, and reviews the Nikon D70s.
