"It Smells Like Ozone"

I had a test in class first thing in the morning. After that, Joe Pow taught the class. We started the unit about Digital Imaging and Detectors. It was really interesting. I learned about the gray scale and the structures of CCD's and CMOS in cameras.

The results of the PVA were the black dye was too dark. I dyed another part of the PVA with the brilliant crestyl blue and iodine. After several minutes for it to dry, when I came to look at it, the yellow in the iodine had disappeared. All there was left was clear solution on the PVA. At about 3:45, we went to the Laser Stock Room to get trained on the lasers.
