When TV first came out my family had other plans for our money. But later on, the box came into our lives, with all its rubbish... and wonders. We quickly became blasé about 'special effects' like people appearing and disappearing (you could often see the tiny slippages of the other cast members as they tried to stay still while the camera was stopped to allow the object person to leave the scene), and a favourite was 'twins' or people talking to themselves, positioned on either side of a 'line' in the background somewhere. And we quickly grew tired of the corny 'people driving in cars but actually it's the the background moving' effect.
But occasionally there'd be something quite spectacular that would cause my Mum to say Her Line: 'So how did they do that then?' to which my Dad would respond 'fishing line' or 'model' or some such. We knew this as Trick Photography.
These days it's all so wonderful. Star Wars was clever and brought us Blue Screens and CG, but then the LOTR* brought us motion capture, realistic CG water and flames, and computer generated 'mass' behaviour for crowd scenes, and goodness knows what else.
Kevin Karsch's PhD project takes the manipulation possibilities of the likes of Adobe Photoshop for still images, and superimposes objects, plus movement, plus incredibly good colour and lighting, to the level of the astonishing.
You can't believe your eyes. Not 'you won't', but 'you can't'.
