What are the most commonly used filters for SLR cameras? How much is a filter? Does it matter?

1, coated UV mirror 200-800: protect lenses, neutral lenses, maintain perfect color balance, and protect precious lenses. After multilayer coating, the lens can reduce glare without affecting exposure.

2. Polarizer: 200- 1500: used to increase color concentration, deepen sky blue, highlight white clouds, and eliminate reflected light from nonmetallic surfaces such as glass or water. It can also reduce the soft focus caused by large fog in landscape photos, but it does not change the tone balance of the whole picture.

3. Gray gradient lens: 70-800: The most important purpose of gradient lens is to darken the sky while retaining the correct brightness of the ground. In fact, the B+W gradient mirror is more used to create the atmosphere of the picture.
