|

It looks like there is a new meter in the store that has some really good specs. I didn't see it in the review (or I missed it). Does it still need to be profiled to a spectro? If so, is the i1 Pro good enough or do you need a Jeti?

Also, props to Connectted for bringing this to the attention of everyone.

For the best accuracy, any colorimeter should be profiled periodically (or before each use) to a known accurate meter like a spectro. Whether you use a $1K i1Pro2 or a $10K JETI depends on the accuracy you need/expect. Whether you do this at all also depends on what sort of accuracy you expect. The JETI 1211 is a reference device (5nm) while the i1Pro is "only" 10nm.
To quote our JETI order page:
Quote: | At some point many professionals conclude that their work requires a reference colour analyzer. SMPTE has established standards for such a device. It must measure color accurately to within ±0.002 xy at or above 10 cd/m2 and luminance accurately to within ±0.5 cd/m2 for white field measurements. These are very exacting specifications that no tristimulus colorimeter can achieve, at least for chromaticity. For this level of accuracy you must have a 5nm spectroradiometer.
Unfortunately, such devices are not cheap. The Photo Research and Minolta reference devices start at about $15,000 USD and go up to near $30,000 USD. The X-Rite EyeOne Pro / EyeOne Pro 2 is reasonably affordable, but it is a 10nm device that cannot routinely achieve ±0.002 xy accuracy.
Recently, a German company JETI Reference Instruments has developed two true reference spectroradiometers, the Specbos 1201 (also known in the U.S. as the Orb Optronics SP100) and the Specbos 1211, that solve most of these problems. |
The CR-100's temporarily on sale too for an extra $300 off, so pick up a couple!

I get the accuracy. I couldn't figure out if out of the box this meter was much more accurate than the less expensive colorimeters like the Display 3. I have an i1 Pro already, so it isn't that big of a deal.
Yeah, I will put one in each car for spares.
I saw the price and for someone getting into pro calibrating the package is a good price.
