Kofetkanje.. oz ko Neza pripelje nogice na ogled.. oz test X-Rite ColorChecker Passport-a..
Verjetno že naslov pove več kot dovolj, cilj dneva je bil test novega X-Rite ColorChecker Passporta.
Neža in nogice so bile pa dodatek 
(zgornja slikca NI barvno skalibrirana, da ne bo pomote 
)
Kdor ne ve kaj je ColorChecker, ga najverjetneje niti ne potrebuje, gre pa za komplet barvnih kart za kalibracijo beline (white balance) fotoaparata in kalibracijo barv RAW formata pri kasnejši računalniški obdelavi. Do zdaj sem uporabljal sivinsko karto in lastno barvno karto, kar je zadovoljilo 90% mojih potreb, zaradi prihajajočih projektov in potrebnega čim boljšega barvnega ujemanja sem workflow nadgradil s ColorCheckerjem.
Sama uporaba ColorChecker-ja je zelo enostavna - pri vsaki spremembi svetlobe enostavno naredimo referenčni posnetek karte. Po prenosu fotk na računalnik kreiramo barvni profil, ki ga potem nanesemo na vse fotke z istimi svetlobnimi pogoji. V ColorCheckerju imamo na voljo tudi sivinsko karto, tako lahko hitro in enostavno nastavimo tudi pravo belino. Paziti moramo samo na pravilno osvetlitev in da karta zapolni večji del kadra.
Seveda pa moramo imeti tudi pravilno strojno skalibriran monitor, drugače je uporaba ColorCheckerja praktično brezupna saj barve ne bodo pravilno prikazane.
