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.

While it's not appropriate to put music over a news package, some video formats call for it. Montages, movies, etc. are some such formats. Since it is so important to understand and respect Copyright Law, I thought I'd post the following article from the Journalism Education Association which includes links to royalty-free music. Don't forget the audio library that we already have: www.Soundzabound.com Enjoy! Royalty-free music and audio for video production Below is a list of sources for royalty-free music and other audio tracks for video production. Although using music in news stories isn’t always a good idea, there are many times when we need music to enhance a video or broadcast journalism project. Intros for newscasts, sports highlights, tributes and slide shows can all benefit from an appropriate soundtrack. For more info on how to use music legally and ethically, check out this story about copyright and fair use, and take advantage of legal advic...
