Defect Maps (again)

[aworonow]

Hi All,
  I'm trying to use binarization to make a bad-pixel map with both hot and cold pixels. I load my master dark and run binarize. If the slider is to the left, I get a preview with black pixels on a white background. Slider to the right and I get white pixels on a black background. The flip from one to the other is very sharp! I take it one of these shows hot and the other cold pixels--right? So, I can invert one, add it to the other (pixel math) and save the result as the defect map. But should the defect map be black pixels on white or white pixels on black? Does it matter?
  Thanks, Alex

Hi
Try the binarize process on a real preview, not the real time one. You need a carefull fine tunning to get the bad pixels.

In DefectMap's philosofy, white is related to good pixels, and black to the bad ones. You may also interpret that as a percentage value (black is 0.00 and white is 1.00) of "goodness".

Much thanks...I'll get it with this help!
