Here I will show an animation 線合成/Sen-Gōsei different case from previous one
In this case,
You already realized that only shadow or highlight are going move maybe. Like this, you can use 線合成/Sen-Gōsei technics




I did short cut the process do in-between because I couldn't have much time to do that. Instead this, I used "Over Lap" on the animation. The shadow and the hi light are going to change slowly fading out to next Douga



___________
OL / Over Lap
Overlap two consecutive shots (screen)
_____________
中OL / NakaOL
Using Overlap in the shot
EX. BG OL, A-cel OL
OL / Over Lap technic is very useful when you don't have time or when you want cost cut for animation. Probably we can't see this technic in animation nowadays but you can see this in old Japanese animation
By the way, I recorded this process so I can share more deeply content near the future!
What’s 合成/Gōsei???
