I see a few posts asking about CC40R filters for the HS10, I made a lens mounted filter about a week ago from parts ordered from Jessops high street stores. The parts. Lee CC40r filter material 75mm by 75mm this is just a very thin plastic film which is easy cut to size (£7) and a cokin 67mm square filter adaptor ring (£5) which is made from aluminium. If anybody would like a pic of this pm me your mail address. I set the projectors Gains and Bias % settings to those posted by Dave Boswell over on AVS and the difference is outstanding the colours and shadow detail are improved by leaps and bounds plus the greys are much darker, this is a must do for HS10's. After all the bother of making this filter I have found a company selling proper lens mounted CC40R filters the material they use is between 1-1.7mm which is much thicker than the Lee stuff I ordered, the price is £18 delivered. I have been e-mailing them over a couple of weeks about these filters a chap called Ian has been very helpful indeed so I ordered one tonight on line. They can be found here.... http://www.srbfilm.co.uk Klippie.
