3) Strengthening digital synthesize technology of regional animation style: Different scenes show different dramas and environments of the story. Digital post-production is mainly used in effects to make the screenshots vivid. In lighting effects, it takes the scene without lights to be the reference. Three spotlights are scattered above the setting and the parameters such as intensity, colors and reductions are adjusted in a proper way. We can see a great improvement in the color and spaciousness of the setting from Fig.12. The materials of the light, being given the sequence frames of the bitmap, have the effects of light reflection. The distorted digital filter of After Effects can produce the visual sense of refractive light under the water, which imitates a real atmosphere in the underwater world. What’s more, the shot of the overflying of the sunset has been added the Lighting Effects, which has deepened the scene and avoided the visual fatigue.
