One of the first magazines on fantastic filmmaking (eg. horror, fantasy and special effects) out there was Cinefantastique. That magazine existed from 1970 to around 2006. I never subscribed as there are some genres that don't interest me (like horror or zombies) but anything relating to science fiction, stop motion animation, and/or Ray Harryhausen ended up on my bookshelf. In fact, it was the double issue on the Making of Star Wars that got me hooked on visual effects at a young age.
Well...the loss of Cinefex (the journal of cinematic illusions) earlier this year when they announced that they have gone out of business has left a big hole in my reading list so I started searching the web for something on-line (who does print anymore?).
This brought me back to my old favorite Cinefantastique:
Cinefantastique Magazine: 1970-2002 : Cinefantastique : Free Download, Borrow, and Streaming : Internet Archive
Now, not every issue is found here for free, but 182 of them should keep me busy.
I have always felt that knowing the old methods when people actually got their hands dirty to make something look real is a great way to inform your CGI skills on how to make something look real in the computer.
