In this brief tutorial, Geoff from http://geoffmobile.com explains about exposure in video cameras:
-what is ISO? Sensitivity of sensor
-what is shutter speed, 180 degree rule for shutter (should be twice the frame rate)
-what is aperture (size of lens opening)
-discussion about setting exposure in mixed Sun / Shade outdoors
-use of an 18% Grey card
-Neutral density filters (ND Filters) are useful to reduce the brightness of light hitting the sensor on a very sunny day.

thanks! See you next time, where I'll talk about how to control "depth of field"!
