The document provides a conversion workflow using colour temperature and Mired Shift, including how to read results on a combined Lighting/Camera conversion chart. Examples show conversions between common light temperatures (e.g., 6500K to 3200K) and list available filter options. A product description section details transmission, absorption, and chromaticity coordinates for specific tungsten-to-daylight and daylight-to-tungsten conversions.","# technical\n\nfilters  \n748  \n238  \nThe LEE range of technical filters has been developed toaccurately convert and manipulate light sources with a highdegree of accuracy for technical situations. A full range ofdaylight, tungsten and fluorescent conversions, neutraldensities, diffusers, reflectorsandscrims, are all available in avariety of sizesand materials to suit the required job.  \n A touch of art, a lot of science.  \n  Conversion Chart 35  \n  Conversion Filters 36  \n\n\n\nAcrylic Panels 37  \nCorrection Filters 38  \nReflection Media 39  \nProtection Media 39  \nDiffusion Media 40  \nIn addition to our broad range oflighting filter, we also produce thehighest quality camera filters in bothresin and polyester.  \n34  \nconversion chart   \nHow to use  \nSimply draw a line from the Colour Temperature value of your Original Light Source, to that of therequired Source. Where the line crosses the central band, read off the Mired Shift value. For yourconvenience we have added both our Lighting and Camera Filters at their appropriate positions inrelation to the Mired Shift Scale. The Lighting Filters are positioned on the left ofthe Mired ShiftScale, whilst the Camera Filters are on the right.  \nExample 1 (Lighting Filter)  \nTo convert an original source of 6500K to 3200K. The line has been drawn as an example. Youwill note that it crosses the central band at just over +150 Mired Shift.
