He maha ngā āhuatanga e pāngia ai te tirohanga a te pouaka whakaata me te ahua o te whakaahua, mai i ngā āheinga o te mata whakaatu ki ngā āhuatanga roro me ngā āhuatanga tangata. Haunga te mata whakaatu, he nui te pānga o te taiao e mātakitaki ana tātou i te ahua ki te tirohanga a te tangata ki te ahua o te ahua. 

Hei whiwhi i tētahi pikitia tino rerekē, me whakakore te māramatanga o te taiao e pā ana ki te mata. Engari ehara te pōuri rawa i te otinga pai nā te mea ka pāngia ngā kanohi e te mamae.  

E ai ki tā Joe Kane i tuhi ai hei heamana mō te Rōpū Mahi Aroturuki Ngaio/Studio a SMPTE,Ko te tae o te mārama i muri i te huinga me rite ki te tae o te rā i te rangi pōuriuri, arā, ki te 6500K. He rite tonu tēnei ki te tae hina i runga i te huinga kua arotauhia tika. Kaua te mārama ā-taiao e neke ake i te 10% o te mārama tihi e puta mai ana i te huinga tonu, koia te mea nui hoki o te whakamahi i te dimmer.

Rama Maama bias lights he tino tata ki te 6500K me te CRI o te 90+. Engari i te hoko i ngā rīpene LED hokohoko e kiia ana he bias lights, ka tiki mātou i ngā diode o te kounga teitei, ā, ka hangaia ngā rīpene mā mātou anake. Arā, ko ngā rā o ngā LED kikorangi, kakariki rānei te tae bias lights kei muri i a mātou, he waimarie.
