Assignment # 8 - Color Temperature

Color Temperature is a characteristic of light that we are not always aware of.  Our eyes and brains are able to see colors as they are in every lighting situation, but light gives off color.  Our cameras need to be adjusted in order for them to reproduce color video the same way our brains see the world.  We white balance the cameras (sometimes black balance) in order to give the camera a reference so it can reproduce colors accurately in our final video.

Beginning students - Please study the Power Point and learn the concept of Color Temperature and please complete the worksheet below the Power Point and turn that in to me, sharing it with me on Google Docs (turn link sharing ON and be sure to get a "shareable link") or you can email it to me as an attachment.  I will grade it and let you know what you got.  Please turn this in by tomorrow, May 5th.

You can also study the website and self test at www.cybercollege.com.  You can click on the TV Production drop down menu and go to the Lighting modules to read and self test.

Advanced students - Please continue to work on your documentary (See Assignment #7)
I have decided to extend the deadline for this assignment to Monday, May 13th.  Let me know if you have any questions.
