Hi everyone 1. Can I measure spectro of ambient light using ColoMunki (not just its chromaticity)? 2. For ambient light measurement I need rev. D of i1 device? 3. In general, i1 without UV filter is better for colour management purposes and it more versatile? 4. And most important question: how bad second-hand i1 or Spectrolino device from ebay? It strongly need recertification? Or recertification is not so needed, in general? Thanks for attention
