Chris has an exercise for everyone to work on: building a light library. He talks about how photos with interesting and unusual light are the most rewarding photos since it can create unique or complex images that demonstrate what light CAN do to a picture.
The next photo assignment is GOLDEN. Take a photo of, about, or otherwise concerning the concept of "GOLDEN" and then post it to the Tech Guy Group on Flickr. Make sure to tag it with the word "GOLDEN" as well! And if Chris likes it, it could end up on next month's photo contest review segment!
