they just draw everything by hand and then scan them on a good scanner
they use a drawing pad (instead of a mouse) and MS paint
Seriously ... MS Paint has all the possibilities to make an anime ? How's that ?
Drawing every pixel individually would take months to make an episode ._.
I was really surprised how Shonen-Jump would make an Anime such as One piece or Naruto
What programes do they use ?
Shounen-Jump do not make animations. They are a publisher
This is exactly the same as asking why Bloomsbury made a Harry Potter movie
As for programs depends on the anime. Pushed out for TV generic junk that goes on forever and a day would use Flash, like the Simpsons! Y'know the Simpsons, right and its nosedive in quality?
High quality stuff? Well, I'm glad you asked! You don't use programs if you want high quality stuff. Here's a link to a Youtube account where you can watch some good animation!! That was done by hand. Painstakingly, at least before the movies stole it and destroyed what would have been one of the greatest animated films of all time. Also, that took 28 years to finish.
(fuck anime. get into the history of animation as at artform)
