Rubber bands. Okay, so this week's tip is a bit of "fluff" but it's a great tip to keep in the back of your mind for that proverbial "rainy day." Suppose you have a filter stuck on your lens. That is, you just can't seem to unscrew it. How to get it off? Especially when you're not close to home? Use a rubber band! Preferably a bit on the wider side, wrap it around the rim of the filter (only) and try removing it again. The extra grip of the rubber band is often just enough. If the filter is still not budging, try grasping it by different areas and/or squeezing slightly.
