"I made a butthole-tracking software to make my work more efficient. Basically video consists of a sequence of images. To modify or colour-correct part of a moving image, you cannot do it frame by frame because it would take an eternity! So you need a 'tracking device', which is something that will automatically isolate part of the image for you, like a butthole. That means that even if the butthole is moving onscreen, it will be tracked. Once isolated, you can then start to colour-correct it. Usually, I make it lighter and a bit pinker. You can track almost everything, from a mouth and eyes to a nipple or a mole."
