I (finally!) got my x-rite ColorChecker and I'm about to calibrate my camera for Lightroom.
However, one of my photog friends just told me that these expensive things fade and after 3 months (!) they're not accurate anymore.
That just doesn't sound right - I bet many spend longer time on shelves before being sold! Also they typically only get out of their cover for a few moments when one needs them, right?
Is there any concern about ColorChecker's longevity - assuming I'm not keeping it at the window exposed to the sun all the time?
