I was recently browsing photos of early Apollo missions and noticed that the plume of the Apollo 4 during launch is significantly bigger than that of Apollo 8. Wondering why is that?

I am not a hoaxer or something like that. I don't have even a slightest shadow of a doubt that the people from the planet Earth walked on the surface of the Moon 6 times. The evidence to support this fact is overwhelming. Just really curious why such a difference. Does it depend on payload mass or different engine modes or something like that?
