The burst (or continuous shooting) mode on a digital camera is a new feature for those who have never used a film SLR but a familiar one for most SLR users. However, the way it works – and the options provided – are quite different on digital still cameras (DSCs). Whereas film cameras were dependent on how quickly and accurately the motor drive could jump the film through the film gate, digital cameras rely on the speed of the data processing system and the size of the internal ‘buffer’ memory where the image is stored while it awaits processing.
