Assignment #9 - Light Intensity


Let me first mention that Advanced students should continue to work on your documentary on your life during the Covid 19 pandemic.  Based on feedback, the deadline for that assignment will now be set to Monday, May 11th.

Beginning students - We have been studying numerous properties of light necessary to make educated choices about how to light your scenes.  Today we are going to talk about Light Intensity.  Light intensity is a measurement of the quantity of light that is falling on your subject.  This is important for various reasons including making sure that you have enough Baselight (minimum operating light level for your camera), making sure that your lighted scenes are not to dark or "hot" (bright), and for directing the attention of your viewers to certain parts of your scene that you want them to see. 

Please watch this Power Point and then complete the Light Intensity Quick Quiz below the Power Point and turn that in by Monday, May 11th.

Cinematic Lighting - Final Lesson and Assignment

Beginning Students: This is the final lesson on lighting techniques, and final lesson of the semester, and I get a little more in depth about cinematic, or film, lighting techniques.  I hope you find this Power Point interesting, as I have used frame grabs from movies to illustrate the techniques. Please look at the Power Point and learn the techniques before you attempt the assignment.  Even though you don't have the luxury of our light kits at school, you can be really creative with flashlights, portable garage lights, windows, a reflector built from foil-wrapped cardboard, your phone light, or whatever you have around the house. to create your masterpiece, which is your final video assignment, described below. There are a couple of great websites that explain film lighting that you can check out. https://www.adorama.com/alc/basic-cinematography-lighting-techniques https://www.masterclass.com/articles/film-101-understanding-film-lighting#how-to-light-a-scene-without-

Assignment # 8 - Color Temperature

Image
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.
