Selecting a filter will take time. Once you’ve selected the type of filter you want, you then have to choose the “grade” of the filter. This is how strong or weak you want the effect to be. Not all camera filters have a grade option, but the ones that do give you a very important decision to make. Unless you already know the type of filter you want, I don’t recommend getting camera filters online. It’s best to go to a camera store with your camera and try out the filter. Yes, some websites do show the effect of filters on your camera, but they don’t tell you that some lenses require you to change the white balance, the shutter speed, or the exposure when a filter is attached.
