Re: [datacolor_group] Re: candelas?

2015-01-27 by billhansen2008@...

The Ticket repeated what we all know about use of the Spyder3 program, but it suggested one thing I hadn't tried - setting the monitor's brightness slider all the way to zero. That allowed the Spyder3 Elite program to measure a brightness of 70 cd/m^2. At that brightness, monitor appearance almost exactly matches prints made with a custom printer profile. The value of 70 cd/m^2 is much lower than any I've read about, but it works. Thanks to David Miller for suggesting that I write a support ticket, and to DataColor for a prompt reply and advice which seems to have solved the monitor/printer problem, for the present.

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.

Bill,

Please file a support ticket so that Datacolor support can help you with this.

(Either you're accidentally clicking and running the older version of Spyder
software which didn't support this feature; and which may still be on
your hard drive; or you're using the newer software but you've skipped past
the screens that let you select the brightness to calibrate to. If those hints
don't help, Datacolor support will).
