Chris always gets a question about whether you need filters or not, and if you do, what filters do you need? Chris says that there are some you need, and some you don't. The two you need include the polarizing filter and a neutral density filter. The Polarizing filter gives you better color, but takes away some light. It's good in bright, direct sunlight, making it great for the beach. It works much like those polarizing sunglasses. What about a circular polarizer? Chris says that these have two layers, one with lines and one with a circular array. As you rotate the filter, you get a better look, so you can dial in the image according to the light or reflections you're dealing with. The neutral density filter is like sunglasses for your camera. If you want longer exposures, then a neutral density filter is for you. Or, if you want to shoot wide open in sunlight, the neutral density filter will compensate for having that aperture wide open by limiting the light. So you can have nice bokeh while being out in the bright sunlight.
Chris says you don't need a UV filter. The camera salesman will try and sell you those. They were important when shooting in film, but in digital cameras, it's already built-in. So you don't need one. They'll also say that a UV filter will protect your camera lens, and that's true. But if you're going to buy one, don't buy a cheap one. It'll leave its mark on every photo you take. Chris says a lens hood is far better at keeping your camera lens safer, though.
Don't forget our current assignment - "Turn." Take a photo of, about or otherwise concerning the concept of "Turn" and then post it to the Tech Guy Group on Flickr. Make sure to tag it with the word "Turn" as well! And if Chris likes it, it could end up on next month's photo contest review segment!
