Why create visual effects

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


Three scenarios for vfx

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?


Format

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

Film Formats

  • 65/70mm

    • When used horizontally, it’s called IMAX

  • 35mm

  • 16mm (used for television)

  • 8mm
