4 In Video, the shutter remains set Shutter Speed – amount of time the camera shutter is open during the exposure of one frame. (Standard – 1/50 sec or twice the frame speed) Frame Rate – number of frames recorded per second. (NTSC Standard – 24 fps)

5 In Video, there are other options Neutral Density filter Off for no density filter ¼ cuts light intensity by up to about ¼ 1/16 cuts light intensity by up to about 1/16 1/64 cuts light intensity by up to about 1/64 Gain (like ISO) – amplifies the image artificially, does not increase the sensitivity of the sensor, causes visual noise L (0db) best dynamic range M (6db) increases the image amplifier H (12db) increases image amplifier more

6 Exposure Decision Steps 1.Make an Aperture - Priority decision by adjusting the camera iris according to your desired Depth of Field. 2.If image is overexposed, add Neutral Density filter to cut the amount of luminosity hitting the sensor. 3.If image is underexposed, switch the Gain Level to amplify the image, but expect increased image grain.
