Ever wondered if you should buy filters for your lenses?
First of all, what are they? and why would you want to buy one?
Filters are things you attach to your lens to accomplish different effects. Back in the film days, it was the only way to accomplish certain tasks (back then, there was no photoshop). If you’re a purist, it still is the only way to accomplish them. I am not a purist, I believe in taking a photograph the best I can in-camera, then making it look the way I want, in post process.
There are a lot of people out there that say anything you put between your subject and your lens is going to deteriorate the quality of your photograph. This is true, however, some filters allow you to do things you otherwise wouldn’t be able to do. In that defense, what good is a photograph if you can’t get it?
I believe there are only 3 filters worth buying- UV, CP, ND.
First UV. It’s purpose is to filter out ultraviolet light. Who cares… there is little to no visible affect to your photo. Because of this, it makes a great protector to your possibly very expensive lenses. These filters are generally inexpensive, and can protect your lens from getting scratched, dirty, or even broken. I have one of these for each of my lenses. These filters are generally between $20-$50 depending on quality
Second CP- Circular Polarizer. My favorite filter. It’s primary use is to allow you to control reflections, make your skies bluer, but also, allows you to slow down your shutter (it allows less light through it). I have one of these for each of my lenses as well. These generally start at about $50, but can get very pricey if you want a high end one.
Last of all, ND. This is a neutral density filter, available at different densities. The most common use for this is to slow your shutter and get those dreamy waterfall scenes. The filter helps you not have to make your aperture super small in order to do it. Though another purpose would be to use larger apertures in bright light to get a shallow depth of field. These usually start at about $20, but it’s not unusual for them to be several hundred dollars.
