Shooting ND Filter Warning Display In order to adjust the amount of light when you are shooting at a relatively bright location, the diameter of the iris may become extremely small, causing blurry effects to occur as a result. This phenomenon is known as "small aperture diffraction". You can make appropriate use of ND filters to prevent it from occurring. This unit displays an ND filter warning when necessary to prompt you to select an appropriate ND filter. 1 Set [Main Menu] B [LCD/VF] B [Display Settings] B [ND Filter] to "On+Assist". (A P107 [ ND Filter ] ) 2 When the iris diameter becomes too small while adjusting the light intensity, or when an ND filter is used in a dimly-lit location, the ND filter display starts blinking. Adjusting the White Balance Adjust the white balance according to the color temperature of the lighting. You can select the adjustment mode according to the shooting conditions. As the color of the light (color temperature) varies according to the light source, it is necessary to readjust the white balance when the main light source illuminating the subject changes. . Automatic White Balance Mode (FAW: Fulltime Auto White balance) 1 Press and hold the [FULL AUTO] button to set Full Auto mode to off. 2 Assign "FAW" (Full Auto White Balance) to one of the three [WHT.BAL B/A/PRST] switches. 0 You can set the Full Auto White Balance feature to either "A", "B", or "PRST" in [Camera Function] B [FAW]. (A P97 [ FAW ] ) 0 If the position assigned with "FAW" is selected using the [WHT BAL B/A/PRST] switch, the Automatic White Balance mode is enabled and an appropriate white balance is automatically adjusted according to the color temperature of the lighting on the subject. Caution : 0 The accuracy of [FAW] is inferior to that of Auto White Balance. 0 When the power of the camera recorder is turned on with the [FAW] mode selected, it takes about 15 seconds for the colors to stabilize. 60 Setting the ND Filter
