paulears Posted February 5, 2016 Share Posted February 5, 2016 Watched how they make Lee Filter on How It's Made this morning. I'd always assumed the polyester was dyed, but was surprised to see that the colour was actually bonded to clear polyester, sitting on the surface of the clear carrier. Then it showed photographic filters which were dipped in hot dye, and they would then let the colour inside the plastic rather than sit it on top. All these years of using it, and never knew how they made it! Funny how I've never ever seen the colour scratch off? Link to comment Share on other sites More sharing options...
sandall Posted February 5, 2016 Share Posted February 5, 2016 Watched how they make Lee Filter on How It's Made this morning. Obviously got far too much time on your hands! I have a vague recollection (that's how they come these days) of catching that one late at night some months ago - fascinating. Link to comment Share on other sites More sharing options...
tom_the_LD Posted February 5, 2016 Share Posted February 5, 2016 I remember many years ago (must've been 2010) actually going to the factory and having a tour around. Was a very interesting day. I even got to make my own gel which I've still got kicking around somewhere! Link to comment Share on other sites More sharing options...
Richard P-W Posted February 5, 2016 Share Posted February 5, 2016 I've seen a piece that had been baked long enough for the colour to "craze" and shrink on the substrate. It promptly disintegrated as soon as it was touched! Link to comment Share on other sites More sharing options...
Don Allen Posted February 6, 2016 Share Posted February 6, 2016 This is why Rosco users say it is a better gel, because the dye is diffused through. I use Lee because it is what was available when I learnt lighting. I was taught to have the colour side face away from the lamp or lens, to increase the life of saturated Lee gels.

paulears Posted February 6, 2016 Author Share Posted February 6, 2016 You see that's the thing, I've never treated it as even having a front or back! Link to comment Share on other sites More sharing options...
DNT Posted February 7, 2016 Share Posted February 7, 2016 Ditto! In over 40 years at this madness, I never knew there was a front and a back to gels!! How can you tell the difference? Are you sure this is not like the glass hammer and the striped paint? If this post was on April 1 I would not be surprised!! However if people have visited the factory and have seen it in production it must be true. Link to comment Share on other sites More sharing options...
sandall Posted February 8, 2016 Share Posted February 8, 2016 I seem to remember that Cinemoid had a front & back, & that (if you remembered) you had the coloured side away from the lamp. Link to comment Share on other sites More sharing options...
musht Posted February 8, 2016 Share Posted February 8, 2016 Cinemoid was cast in a block and planed off in to sheets at Courtalds in Ipswich , think it came up here before. Might be thinking of much thinner Chromoid which was Strands answer to Rosco Supergel. Link to comment Share on other sites More sharing options...
paulears Posted February 8, 2016 Author Share Posted February 8, 2016 That was Chromoid, wasn't it? Still got a few sheets of cinemoid in the gel room. It's gone a bit cloudy over the years, but uniformly. Link to comment Share on other sites More sharing options...

itiba Posted February 8, 2016 Share Posted February 8, 2016 Well I've just looked at the ol' swatch book and I can't see a 'front' or a 'back' to the gels so wonder what the secret is. I also have heard contradictory advice about whether the colour should on the inside or outside of the diffusion. How it's made also covered the making of the LED Source 4 recently.

Crew.Steve Posted February 9, 2016 Share Posted February 9, 2016 Back in the 60s I was taught that the gel always sits outside of any diffusion to prolong the life of the gel. We also had a strict policy of saving the lights as soon as the show was over. Between shows the manager even used to swap out all the lamps for lower power ones which made plotting during rehearsals something of a challenge - so, when he wasn't looking, we used to swap them back again. Mind you, lamps didn't last so long 'in the old days'. Ah the smell of burning dust and the occasional spit of molten copper - those were the days...
