Hi guys. - I need some help / inspiration for a competition theme of 'Noise'. The obvious ones have come to mind; Child screaming, hammer striking... I want something different which will stand out. Does anyone have any successful examples / ideas of how to take a decent looking picture of a moving speaker cone? Or any novel of neat ideas which can be staged? The likelyhood of finding an opportunistic example within the deadline is small. Thanks in advance for your time / thought. Chris.
