oi, i wish I had more lighting experience to help you out. if I have time I will put together my ghetto product studio again and put a rotifeast bottle I have and see what I can do. it's notorious for plastics and such to have glare no matter what =/ keep us updated on what you find. hopefully I can get around to trying some stuff out too. have you looked at fredmiranda.com's lighting / studio forum? http://www.fredmiranda.com/forum/board/44 Definitely a good resource. You can also try asking about taking product shots of bottles, I'm sure you'll get a lot of feedback.
