Is there a way to measure the brightness of a monitor in candelas, using the Spyder3Pro ? I recently had a professional printer profile made by a well recognized maker of such profiles. Prints using that profile are too dark. In email discussions with the profiler, he noted that the most likely reason is that my monitor is too bright. He said he keeps brightness of his monitors at ~ 20 cdm2 (candelas/square meter). He suggested that I re-check the brightness of my monitor, which of course I will do. But I don't know how to relay information about candelas to him.
FWIW - The monitor calibration is checked with Spyder3Pro every month, and it was re-checked just before the targets for the profile were printed. The appearance of images on my monitor, dating back to images shot and processed in the year 2000, is appropriate and has not changed noticeably.
