Chris says it's a drag when you're planning to shoot an eclipse and you get cloud cover! Not much you can do about that. But what he thought was cool is people using a colander as a pinhole camera. So you end up with not one, but a hundred eclipses shining on the ground. The same can happen with holes in trees. Look on the ground during an eclipse and you'll see little eclipses under trees. Amazing.
Shooting the sun is called Solargraphy. You can take a piece of photo paper, and then place it into a cylindrical container that is light tight, like a pringles can that's been blacked out. (but you have to do it in total darkness). Then prick a hole in the can and you can turn it into a pinhole camera that captures light onto the photo paper. Put it out for several days, weeks, or even months. Then, when you take it out, in the dark again, you can put it in a scanner and scan it. You'll end up with a cool picture without having to use chemicals to develop it.
Don't forget our current assignment - SHADOW. Take a photo of, about or otherwise concerning the concept of "SHADOW" and then post it to the Tech Guy Group on Flickr. Make sure to tag it with the word "SHADOW" as well! And if Chris likes it, it could end up on next month's photo contest review segment!
