Portrait photography lighting using a shopping bag as a light modifier
http://www.GoodLightMag.com/02 - It's time to pull off an effortless yet impressive trick. First, set your speedlight to 1/16 power and place it inside a white shopping bag, facing upwards. Next, place the bag about 60 cm (2 feet) away and slightly
to the side of your nice model, at a 45-degree angle – so when the flash goes off it will light her up nicely. Adjust the camera to 100 ISO and f/2.8, then pick the shutter speed that is right for your camera (we used 1/200s.
At last, point your camera and shoot away! You find the long version of this tip and many more in Good Light! Magazine Issue 02.
I wish you good light!
