He maha amateurs ui te kaha tātari o radiation hihi katinga, no te mea ko ngā te whakaahua kore pānga (rite ki te kaiwhakanao, tiaki tātari kopu mamati). E ai ki taua whakaahua mo te hanga o ngā kamupene tuku kōrero whakaahua e noa haki i roto i runga i te photographer runaruna.

Whakamahia UV-whiriwhiringa ranei kahore, e whakatau ia he photographer runaruna, engari ki te tango mehua ki te tiaki i te arotahi, he tika taua mea, no te mea kia ara ki runga ake i te utu o te kāmera iho te utu o te pūnaha whatu pai.
