Homemade colored and diffusion filters may not match the quality of commercial ones, but they can produce results that aren’t otherwise possible. Here are a few ideas to try.
• Crumple up a piece of cellophane, then smooth it out and attach it to the front of your lens with a rubber band.
• Apply a fine mist of spray matte material on an unwanted clear filter or a plain piece of glass.
• Brush some clear nail polish on an unwanted UV filter. Try different patterns for a variety of possibilities.
