Google hasn't really yielded many good results for me on this one. What's a good website from which I can purchase CTO & CTB gels?
You can contact Professional Lighting Services on 09 302 4100 - They sell Gels (Diff, CTO, CTB) for about $30/m (ex. GST).
Do you have anyone running a lighting truck down there. On each job they may throw out more than you need. CTOs that have been stapled outside a window once may be given away (I got some that way). If you weren't working on the show, take beer.
Thanks guys. Good thinking Gregg!
Get in contact with some companies that make gels. Tell them you're a young filmmaker and are looking to sample their wares. They should send you some free samples, with the mind that they'll be building customer loyalty. This worked for me with Roscoe, but I don't know if they'll ship to NZ. In any case, worth a shot.
