Polarized lens Does a polarized lens work with a digital camera? If it does work am I right about vertical no effect and horizontal full effect? How beneficial has anyone found a polarized lens?

Folks at dpreview are convinced it works.  And aim the arrow toward the sun, as I understand it.

A polarized lens will work on a digital as well as it would on a film camera.

The problem is related the polarization of the two antennas you and your friend are using. You are using a dipole antenna which is polarized horizontally and you friends using an upsidedown whip which is vertically polarized. My advice is as close as you are, is hang your dipole from something high enough that the top say is hung in a tree or off a tower and other end of the dipole is attached to an anchor in the ground. You have basically made a full wavelength vertical, which you friend should build himself.

Tip on polarized sunglasses.Polarized sunglasses are a tool you have to fight...


Tip on polarized sunglasses.Polarized sunglasses are a tool you have to fight the effects of sun glare. The design for these sunglasses was first developed and implemented more than 60 years ago. When they were first developed they were used mainly by those in sports, as a way to help protect the player's eyes from sun glare. While they are still heavily used as sports sunglasses, they are now used by anyone, anywhere. Their benefit is in providing you with the ability to see well even in the harshest of sun glare conditions.<br /> How Polarization Works<br />Understanding polarization can help you to see why you need to use polarized sunglasses in any situation in which, there is a lot of sun glare. When sunlight hits a surface, the photons in it are vibrating in one direction, which means it is polarized. When this happens, the light travels away from that place, called the pole-to-pole movement, on that plane. <br />When does it make sense to have polarized sunglasses?<br /> * Light reflects off water with glaring effects (if you have ever been fishing and been unable to see the water, this is why)<br /> * Light reflects off wet pavement in the same matter, which means having them while driving is highly effective<br /> * The snow can also reflect very brightly and polarized lens sunglasses can be helpful at seeing through this<br /> * Sun glares off the car's bumper in front of you in traffic, polarized sunglasses can help<br /> * Light beams off the baseball bat at the game you are pitching, polarized sunglasses can help minimize this<br /><br />Using Polarized Sunglasses Appropriately<br /><br />Because polarization can be blinding in some situations, it is essential to use polarized sunglasses whenever you could be exposed to this light. One thing is unique, though. The color of the lens used in polarized sunglasses can be important, as different types of reflective surfaces are dealt with better with different colored sunglasses.<br /> * Use gray sunglasses for an all purpose type of protection, it provides true color perception, too<br /> * Yellow sunglasses are a good option for blue light, such as driving on a cloudy day<br /> * Red is a good option for virtually all sports activities as it works well when there is a lot of bright sunlight<br /> * Blue polarized sunglasses are an option to use when playing tennis and golfing, especially on a day that is partly cloudy<br /> * Choose brown polarized sunglasses for driving and fishing, as it is a good option for improving the contrast you see<br /> * Go with copper polarized sunglasses when you need good contrast (it provides the maximum amount)<br />Polarized sunglasses are an ideal investment when it comes to protecting

How do you adjust the vertical lines going across my screen?


The vertical deflection circuit of your tv has a problem.
First, try to replace the vertical ic. This ic can be found near the plyback or horizontal section. It is a linear ic with heatsink.
If nothing happens after replacing the ic, replace all the polarized capacitor near the ic and resolder the components at the vertical section.

I inherited a nikon d 40, It has a polarized lens installed on the regular lens, I wanted to install a wide angle lens that I got and I dont know how to remove the polarized lens to do that. It just spins...


It sounds like there are two different issues here.

The polarizing filter is in two parts. There is a ring that spins and a part that screws onto the front of the lens. Grasp this part and unscrew it from the lens to remove the filter.

To remove the lens, look at the camera from the front. At the three-o'clock position around the lens, there is a button on the camera body. Hold this button down and turn the lens clockwise. To attach a lens, align the dots, gently press the lens into the mount, and turn counterclockwise until it clicks. This procedure is on page 8 of the manual. If you can't find your manual, you can download one from

CANON SD1000 can't TURN vertical downloaded video into horizontal


If you have windows movie maker (its part of the default installation of windows XP) you can use the rotate filter in the video effects tools.
Import your video into movie maker and select "Video Effects" under tools.  Scroll through the various effects until you find the "rotate 90".  Apply the effect and save the video.
I hope this helps!

Polarized lens


They definitely work. I just got one in the mail today for an FZ5. Try taking a picture through a glass window to see if it elimates the glare and reflections. This is an way to test the filter.

Filter


Skylight filters don't generally block UV, they change the colour tint optically, which you can do without danger of image degredation in post-processing, so I woudn't really recommend using a skylight filter for digital cameras. I haven't tried a UV filter on my fz10, only my circular polarizer. From what I've heard however, a uv filter may act as lens protection (or use the lens hood), and might in some circumstances reduce haze (rarely), and there are unconfirmed rumours of possibly reducing purple fringing. If anyone could ever confirm this, I might consider one. Otherwise, UV filters also seem peripheral for digital photography. Probably the most important optical filter you can use is a polarizer. This can cut a lot of excess scattered/polarized light and reduce excess contrast, increase sky colour saturation, etc. It's effects are extremely difficult or impossible to get in editing.
