  Ultrascope readings – unique

  Posted by Neil Ryan on July 4, 2012 at 2:32 am

  What does it mean when I set my Ultrascope Profile limits to 0 & 100 ire and the error log shows errors of ” -0 ” Lower Luma and “100” Upper Luma?
  What kind of number is -0? And assuming it means ‘0’
  why are 0 and 100 errors? (rather than something less than 0 or more than 100?

  Neil.

  I can only assume that your blacks are going below 0 and whites are going above 100 IRE. I quality control all of our commercials that come in, and it’s pretty ridiculous the amount of spots that are at 115 IRE, especially when it’s so easy to fix.
