I just got a Hoya Ultra-UV Circular Polarizer for my 828. I haven't used it yet, but I was wondering if there's any helpful tips to learning how to get the best out of it?
On a side note, I'm thinking of taking some sunrise photos tomorrow morning, does this filter affect how I should set the white balance and also does this affect advice as to the best way to use the filter?
Thanks, Paul. |

They are hard to use on digital cameras, as the viewfinder compensates for the effect of the polariser as you turn it round, so it's hard to tell where the optimum placement is.
They are next to useless when you point them at or away from the sun, the optimum way to use them is at right angles to the sun.
You either point the white dot on the filter at the sun or at 90 degrees to the sun... I forget but I think it's at 90 degrees. The way to tell is to take it off the camera, hold it up to the sky and find out where the dot is pointing when the effect is at it's best.
I'm not sure a polariser will help with sunrise shots, but then I haven't tried. Traditionally it's best used when the sun is very intense in order to darken your sky so you can keep detail in both the sky and ground, and to make the clouds stand out more. In a sunrise, I would have thought that you want to keep the colours in the sky as they are. They don't have an effect on white balance. They do however cut out a lot of light that reaches the camera, so if you use them in low light make sure you take a tripod. |

Not true on DSLR's, you will see the effect of the polarizer and you can adjust the effect.

Just remember, a filter that affects the temperature of the light could affect the white balance. Try not to use Auto if shooting jpeg.

I assumed people would realise that |

If it's a decent polariser, the temperature should remain unchanged. Also, you wouldn't want auto-white balance to take away the enriched, darker colours a polariser provides. |

| I think it may not be a good idea to use at either sunrise or sunset as light may be diminished at those times of the day and you are going to reduce light even further with a polarizing filter, which will likely introduce noise into the shadow areas of the image. |

Greetings,
I'm not sure about Hoya's filter, but the Sony Circ. Pol. will show its effect, although it may take a 1/2 sec or so to show up on the screen, so turn slowly, lol.

| Thanks for tbe help so far, I'm looking forward to it. It probably won't be exactly sunrise, as I'm going on my way to work, and I usually go through tne spot a little later, but rhe sky is still an orange colour and the sun is still fairly low. I'm going to take my camera, but it's currently raining so I'm not sure what I'll get. |

I recently (2 weeks ago) got a kenko Circular Polariser for my f828. It's true about having zero effect into the sun, and very little out of it, most at 90 degrees. Also about the camera trying to compensate for the filter. I keep mine on Manual for best results. I expected more from it's reflection reducing ability though.. Colour temperature does change a little at sunset.
Does anyone know where the white arrow goes? I just turn 'till it looks good and shoot. |

Let me grab the opportunity to make a small quastion, maybee a common one:
Will a neutral UV filter(loke sigma's for example) will reduce somehow lens flare? And being a neutral one can it be used on inside home photos? I was planning to buy one just for protection... Especcialy when shooting near the sea.

UV filters are used to cut haze in the atmosphere. As far as reducing flare, a lens hood is your best bet for that or just change the angle of the shot.

| Adding an extra filter will increase flare. The more glass there is, the more surfaces there are to cause flare. The better the quality of the filter, the less flare. |

and the best part is your shooting digital anyway...take one with it on and one with it off and if you don't like them, hey your not out any film. I learn best by trial and error...usually more error.
