On Tuesday while we were still at school it was looking pretty likely that there would be a snow day the next day. "What will you do if we have a snow day?" a colleague asked me. "I would go to Home Depot and buy some stuff to build a diffusing screen so I can take better portraits of my kids," I replied. Well, we got our snow day and I hesitated about driving out in the snow, but since I had indicated that I would, I did it. I went out when the roads were probably the worst, but I did get to help push the mail truck up a hill.

Here is the diffusing screen I built using a cloth shower curtain and a few PVC pipes. (The screen goes between the flash and the subject to soften the light.)
I just had time to snap a couple of photos today, but not time to really work with it. As you can see in the photo below, now I need to make a reflector to add a little fill on the shadow side.
