Raziskava se osredinja na kakovost barvne reprodukcije pri uporabi različnih svetlobnih virov, ki se pogosto uporabljajo
za osvetljevanje scen v fotografskem studiu, in različnih vrst tkanin kot nastavkov za oblikovanje svetlobe. S temi lahko
svetlobo preoblikujemo v mehkejšo in bolj razpršeno, vendar lastnosti uporabljenih tkanin vplivajo na barvni vtis
in posledično na kakovost reproduciranih barv. Le-to smo vrednotili z analizo barvnih razlik, ki smo jih izračunali iz
odčitanih kolorimetričnih vrednosti barvnih polj testne tablice X-Rite ColorChecker Passport. Ta je bila fotografirana v
nadzorovanem okolju in izpostavljena različnim kombinacijam svetlobnih virov ter testiranih tkanin. Rezultati potrjujejo,
da niso vse kombinacije spremenljivk primerne za uporabo, če je cilj fotografiranja kakovostna barvna reprodukcija.
