Here is a neat idea. If you are shooting against the sun a lot you are probably have your favorite way of blocking the sun to avoid flare. Maybe a fancy lens hood, maybe a nasty flag or a Coroplast frame or maybe even your hand.
If you want to stay consistent and focus on creativity, the folks at Digital Camera World have a great idea for you – build your own super versatile flag.
Using a wire, a few clamps and some bolts you can build a tripod attachable flag that can move around and protect the lens from that killer flare.
