When there's a window between you and your subject, getting a shot free of reflections is tricky. Photographer Michael Courier has come up with this ingenious, flexible hood for taking photos through glass without those pesky reflections or glare. You can make one yourself in about 30 minutes.
All you need to make this flexible hood, dubbed the "Flect", are black canvas, duct tape and a few other cheap supplies. To use it, attach the hood to the glass with the suction cups built into the hood, then place your lens through the cutout in the middle to compose and take your reflection-free shot.
Here's a before and after example (without the hood on the left):
You can fold the Flect for easy carrying in your pocket or camera bag. Michael explains other benefits of using this over other methods:
This is different than using a polarising filter or a rubber lens hood. A polarising filter will add another piece of glass between the sensor/window, not block 100% of the reflections, as well as add a stop to the exposure. A rubber lens hood works great when shooting directly straight, but offers less flexibility when composing your shot or shooting at angles.
Check out the step-by-step instructions on Michael's blog to make your own Flect.
