If you pardon the pun colour deficiency is not a black and white issue. I have always been borderline on red green deficiency. With focus and concentration I can see some subtle differences. My grandfather was an Optemetrist and my mother an Optician so the Ishihara couloir dot test was commonly available around our home growing up. I knew my deficiency from early on. It was not until I learned of the Farnsworth D-15 test and the availability to order a set for myself that I finally had a chance to practice sorting colours for myself that I was able to make some progress. For me it was the professional marine industry tests that I was able to pass.
Excellent little booth which enables me to view prints beside my calibrated display. This helps me to fine tune my images better than I would otherwise be able. Booth illumination brightness can be adjusted to match that of the display.
The Eizo ColorEdge sets the bar in terms of color accuracy and ease of calibration. The self-calibration on a timer is simply the easiest way to keep the device at its best. Nothing else I have ever used comes close. Pricey, but so worth it, and RPImaging really went out of their way to provide great service.
We have been very pleased with the accuracy and improved workflow the eXact has afforded us. It’s ability to easily manage spot libraries for multiple customers through the computer interface is awesome! In addition, its repeatability is far superior to any other units I have ever used. I highly recommend spending a little more for something that will ultimately save you tons in manpower expense in the long run.
