The idea is to use a quality digital camera and expensive image editing software, along with Avia, to find an approximation of 6500K. Specifically, for displays which have a temperature adjustment, or access to the appropriate parameters for adjusting temperature. First I'll describe my proposed technique, and second I'll put some caveats on what I really expect to achieve. Then you lot (especially the ISF techies here) tell me whether it will work. 1) put a 70IRE uniform test screen up (Avia has such a test, if I recall correctly). 2) take a raw picture with Digital SLR camera. Import into Photoshop (or in my case, Phase One), set the white balance to 6500K, and eyeball true white on my 6500K calibrated screen. Or just use the eyedropper idea to see what temperature the result is 3) adjust temperature up or down on the display device and repeat step 2) until happy. What I hope to achieve: A poor mans temperature calibration. An ISF tech can build a 6500K result under a variety of "IRE"s. This method will not. But, it will at least get the image somewhere closer than before. Thoughts? Martin.
