Filter Question for tomorrow

Tomorrow I will be shooting a motercycle event in nasty sun, and picked up a CPL for this purpose. Does anyone know if CPL's have built in UV filtering? Or should I use both the UV and CPL filter. Thanks

UV filtering isn't needed or beneficial on DSLRs and stacking filters isn't advised.

I would recommend a neutral density filter (not a graduated one).

Be careful with the CPL filter. While they are great, they do have limitations and if you could end up making the sky an unnatural dark blue or with very dark corners. Just pay close attention. Have fun

Thanks guys, I guess I will experiment with all combinations since I have the time. Also, does using such a filter reduce the light coming in by a few stops?

A CPL reduces your light by 1-2 stops depending on brand, angle to the sun, and how its adjusted. So don't use it unless you need it.

What is your anticipated problem shooting in bright sun?

What do you expect a filter to accomplish for you? I suspect you may have some unrealistic expectations.

Do you know what a polarizing filter does?

Do you have a lens hood for each of your lenses? If not, that would be a superb accessory to have and use, as they can improve your images by blocking stray light sources that can cause flare and other image degradation.

The problem is that the sun is somewhat behind the riders, so the filter would reduce its glare. Yes i have a lens hood but my understanding is that a filter would linearize the stray light from the sun, and reduce glare coming from the bike's shiny parts

I seriously doubt that a polarizing filter would do much for the sun's glare if the sun is actually in the picture or even close to being so.

Also, to reduce the reflections on the bikes, you'd have to adjust the filter's rotation for each angle to the sun that you were photographing.
