19. Why create visual effects?
• In normal photography we try to reproduce
reality
• In VFX we want to create something that
doesn’t exist at all
• …and also, fool people into believing it is real

20. Three scenarios for VFX
• What we want to see doesn’t exist
• What we want to see is too difficult or
dangerous to photograph live
• We need to “fix” something we have
photographed
• What about Story?

21. Format?
• Whether VFX are shot on film or video
depends on what the effects will be used for
• Often effects shots require much higher
resolution than the viewing format
• The ability to shoot at a variety of speeds is
also a determining factor

22. Film Formats
• 65/70mm
• When used horizontally, it’s called IMAX
• 35mm
• 16mm (used for television)
• 8mm
