I tried to calibrate to 80 cd/m^2 this morning and encountered a "new" problem - the program no longer allows me to select candelas! I know - I'm probably missing something in Settings or Preferences, but I can't find it.
The first couple of times I used the upgrade to Spyder3 Pro 4.0.2, there was the option to set the colorimeter on its ambient light stand, and measure ambient light. I always calibrate, edit images, and print in fairly dim room light. The program indicated low ambient and recommended 120 cd/m^2 brightness of the monitor. I set the monitor at 121 cd/m^2 - the closest I could get it. This morning, that option to set candelas is gone. All that remains is the instruction to set the monitor to factory settings, and then choose a monitor brightness which "is comfortable". The default monitor brightness is 90%, which of course is way higher than recommended.
What am I missing in the Spyder3 Pro program? I know that previous versions did not allow candelas to be measured, but after the upgrade, the option was available originally. Now it's gone - or at least, I can't find it.
