-130-ENGLISHHow the White Balance (Tint)Adjustment WorksVideo recording takes place under various light sources, fromsunlight as the main natural light source to a wide range ofartificial light sources such as fluorescent lamps. As each ofthese light sources has a different colour temperature, each ofthem gives the colours of the subject a slightly different tint.Human eyes can easily adjust to different kinds of lighting andrecognize an object as having the same colour, even underdifferent light sources.The eye of the Movie Camera (lens), however, cannot adaptto the change in lighting and is influenced by the lighting.Therefore, depending on the light source, the picture would berecorded with a bluish or reddish tint. To minimize theinfluence of the lighting on the colours of the subject, anadjustment called White Balance Adjustment is necessary.∫ Auto White BalanceThis Movie Camera offers both Auto White BalanceAdjustment and Manual White Balance Adjustment. When theMovie Camera is in the Full Auto Mode, the internal system ofthe Movie Camera automatically determines the temperatureof the light and compensates the tint of the subjectaccordingly. White is the basic colour by which the tint isdetermined. Because this adjustment is performed based onthe white colour, it is called White Balance Adjustment. Theoptimum settings for several light sources are stored in thememory of the Movie Camera. The internal microcomputercompares the colour temperature of the light received by theWhite Balance Sensor positioned on the front of the MovieCamera with the colour stored in memory, and selects thesetting for the most similar tint.Be careful not to cover the White Balance Sensor (l 12) withyour hand, etc.∫ Manual White BalanceAlthough this Movie Camera stores the optimum settings forseveral light sources in memory to correctly judge the whitecolour, it cannot cope with all light sources. Therefore, torecord under those types of lighting (l 90, 92) which cannotbe correctly adjusted with Auto White Balance Adjustment,use Manual White Balance Adjustment. (l 90)How the Focus Adjustment WorksIf you look at an object through a magnifying glass and moveit closer or further away from your eye, you will reach a pointwhere the object becomes clearly visible. Being focused or infocus means that the subject can be seen with optimumclarity and sharpness. The distance between the lens and thepoint where the rays of light come together is called FocalDistance or Focal Length and depends on the size and shapeof the lens.Human eyes have lenses too, and when we look at objects atdifferent distances, the shape of these lenses changesautomatically so that we can always see the objects clearly.∫ Auto Focus AdjustmentThe image of the subject enters the Movie Camera throughthe lens and is converted into an electrical signal (videosignal) for recording onto tape. Based on this signal, the AutoFocus System automatically adjusts the focal distance bymoving the focusing lens forward or backward.The focus is adjusted on the subject in the centre of theFinder. ! ! !"#$ !"#$%&'()*+,-./012345)*(6 !"#$%&'()*+,-./0123456 !"#$%&'()*+,-./01 !"#$%&'()*+,-./01)23+4567 !"#$%&'( !"#$%&' ! !"#$%&'()*+, !"#$%& '()*+,-./01234567# !"#$%&'()*+,-./0123∫ !"# !"#$%&'()*+,-./'()*+,-01 !"#$%&'()* +,-./0$%1234 !"#$%&'()*+,-./0'123'( !"#$%&'()* +,-./012)34+* !"#$%&'()*+,-./01234(567# !"#$%&'()*+,-./012345,67 !"#$%&'()*+, -./012345' ! !"#$%&'()*l=NO∫ !"# !"#$%&'()*+,-./0123456789 !"#$%&'()*+,-./0+1#2'(345 !"#$%&'"#()*+,l VMVO !"# !"#$%&'(l=VM !"#$%& !"#$%&'()*+,-./01 2345*67 !"#$%&'()*+,-./+-012%34#$ !"#$%&'()*+,-./0123456789 !"#$%&'()*+,-./012 !"#$%&'()*+,-./012$34"#.5 !"#$%&'()*+,-./01∫ !"# !"#$%&'()*+,-./012345678 !"# !"#$%&'()*+,-./0123 !"#$%&'()$*+ !"#$%&'()*+,-./0
