Italiano: Filtro fotografico di forma circolare con lente gialla montata su telaio in metallo Inserzione a pressione davanti all'obiettivo Il filtro è conservato in una custodia in pelle marrone con chiusura a bottone.
I filtri gialli usati in fotografia in b/n contribuiscono a sottolineare il contrasto In alternativa vanno impiegati con pellicole o lastre a colori ortocromatiche e pancromatiche e riducono la luce azzurra e violetta che giunge al negativo.
