The direction of the light is defined by longitude and latitude. • Longitude: A direction (angle), expressed as a plus value for clockwise rotation in the plus direction with respect to the X axis of the input picture. • Latitude: Latitude The following figure shows the relationship between the longitude and latitude of parallel rays, input picture, and test sphere. Z-axis Latitude=+0.25 Parallel rays KF2 = 0.12 KF1 = 0.88 Test sphere KF2 = 1.12 Input picture Y- Latitude X-axis Longitude Test sphere Latitude=-0.25 The measurement unit of direction parameters is the number of rotations, with 360° (1 rotation) expressed as 1.00. The following relationships apply in the example shown in the figure. Parameter Longitude Latitude Setting 0.12 0.12 Angle 45° 45° The fractional part of the setting after the decimal point corresponds to an angle 0° to 360°. If the fractional parts of two setting values are the same, the effect is the same even if the integral parts are different. The integral part of a setting value is used when moving a light source with keyframes. For example, when the longitude of a light source rotates in the clockwise direction from 0.88 (315°) to 0.12 (45°), it rotates in the counterclockwise direction (the angle grows smaller) if the above values are used. In this case, the value of the second keyframe can be set to 1.12 (360° + 45°). Setting the image surface 1 Open the DME >Light/Trail >Spot Lighting menu (4156). 2 Press [Spot Lighting], turning it on. 3 Set the following parameter. You can make the Spot Lighting effect more effective by adjusting the [Total Ambient] parameter to lower the brightness of the entire image. The [Total Ambient] setting is common to the Lighting function. No. Parameter Adjustment 1 Total Brightness of whole image Ambient 4 In the group, select the state of the surface struck by the light. Flat: The image surface is unchanged. This causes the selected light source to appear as the effect. Non Linear: Spotlighting effect is applied to an area to which a DME nonlinear effect is applied. Note The Spotlighting [Non Linear] setting is effective for the following nonlinear effects. For other effects, the result is the same as selecting [Flat]. Wave, Mosaic Glass, Flag, Ripple, Lens, Panorama, Page Turn, Roll. 5 When [Non Linear] is selected in step 4, set the following parameter. No. Parameter Adjustment 5 Amp Emphasize unevenness a) a) Plus emphasizes bumps in texture, minus emphasizes depressions. 0.00 is a flat surface. 268
