My first post in this thread was post number nine.......in it I wrote the following.......
"What I have done is use the "Full Field 100 IRE" test pattern from the HD DVD DVE test disk. My colourimeter probe is a Sencore CP5000, it was set up FACING the projectors touching the screen 18 inches from the left hand edge as you look at the screen (NOT center of entire image and NOT center of left hand part of image), Projectors are D65 colour balanced."
"FACING" was in capitals in post number nine, I already knew at that point that this might get questioned so I wanted to highlight it from the start.........Not saying what I was doing was correct but so that it was clear what I was doing.
What you are now quoting was a development of this thread and a question I was asking to help understand more about this, followed by what I believed to be correct (But happy to hear otherwise) and lastly I mention again the FRONT FACING sensor. My readings were taken with the probe facing the PJ, If I am to change what I am currently doing I would like to know why and understand the reasons behind what I am doing - Currently I face the PJ with the probe as that is what the sencore instructions tell me to do, they made it, I kinda figure thats a good starting point.
"....and if measuring reflected light how
far do you have the sensor from the screen and at what angle?
I believe that the light output is an inverse square rule so distance from light source is not linear and will differ greatly - again this is why I mentioned that my sensor was touching the screen, that gives the lowest possible reading when front facing the sensor."
Gary I think you took "if measuring reflected light" and maybe thought it was a statement, the full sentance then continues with HOW? I meant it as a question.
(I must learn to speak English better
)I would still like to know how far the sensor should be from the screen and at what angle ??? if facing the screen.
