Observation:


Looking at a projection TV with the gray side bars and program

material in B&W (old Movie) I noticed a slight greenish tint in the

movie but not the side bars.


I wonder if matching the movie to the side bars would provide a

more exact grayscale.


Anyone ever try it?

Greetings,


I would not base your grayscale off of this due to the fact that the gray bars on most sets are a function of the sets actual grayscale. If the sets grayscale is not set correctly these bars will not be correct. Also, Black and White film has a differenct gray reference than D6500K. Basically the film industry uses D5400K as their standard. This is why films are transferred and color corrected to the D6500K standard. Black and white films are generally not changed and remain at their D5400K due to the fact that they have no color. The green tint you see could be grayscale related or it could also be that your set has a long decay rate on the green phosphor causing the green to stay lit longer.


There could be many things affecting this.


Best of Luck,
