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 • 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? • 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
