The human eyes have "only" 3 different colour receptors, so multiple spectra can be perceived as the same colour.
(And this without considering all the ways the signal is processed before you actually "see" it.) #Optics#Colour#Color#Vision
A small selection of shots from last night’s spectacular light show over #Groomsport, #CountyDown. #Aurora hunting here has always involved squinting at a faint green smudge on the northern horizon.
Not last night! 😎🤯
I am grateful for the opportunity to walk around the base of Mount Maunganui (Mauao) on such a beautiful day. I was very lucky to visit this beautiful place with friends in the weekend.
I have 3+ #scanners, all with wildly different #color results, as you can see below. At least 2 of them can scan directly over LAN (in Simple Scan).
Ideally I'd want #colormanagement / calibration of scans, ideally with "Simple Scan" (otherwise, how do you do it with XSane?). I have a ColorMunki spectrophotometer, if it helps.
