Ngaba i-gelatin ingasetyenziswa kwizicelo zeefoto?

Mna.Ukubaluleka Kwembali​

i-gelatin yaguqula indlela yokufota ngenkulungwane ye-19, ithatha indawo yeenkqubo ezinzima zepleyiti emanzi. Njengesihlanganisi kwi-emulsions yesilivere ye-halide, yasasaza ngokulinganayo iikristale ezinobuthathaka ekukhanyeni kwifilimu, ivumela imifanekiso ebukhali. Amandla ayo okudumba emanzini avumela uphuhliso olulula, okwenza ukufota kufikeleleke kubantu abangengabo.​

II.Iingenelo zobugcisa​

I-Gelatin ilawula ukukhula kwekristale yesilivere ye-halide, ichaphazela isantya sefilimu kunye nomahluko. Ii-emulsions ze-fine-grain ze-portraits zisebenzisa ubuninzi be-gelatin ephantsi, ngelixa iifilimu ezikhawulezayo zifuna i-gelatin engaphezulu ukuzinzisa iikristale ezinkulu. Ikwakhusela ii-emulsions kumonakalo woomatshini kunye nokufuma, nto leyo eyandisa ubomi beshelufu yefilimu. Nanamhlanje, ukuhambelana kwe-gelatin neekhemikhali ezibuthathaka ekukhanyeni akukabi nakuthelekiswa.​

III.Ukufaneleka Kwanamhlanje​

Iifoto zedijithali zinciphise ukusetyenziswa kwegelatin, kodwa iyaqhubeka nokusetyenziswa kwiindawo ezithile: amaphepha okuprinta obugcisa obuphezulu, apho ubume bayo buphucula ubunzulu bomfanekiso; kunye neefilimu ezigciniweyo, ezixabisa uzinzo lwexesha elide. Amashishini akhethekileyo afana ne-medical imaging (ii-X-ray) asasebenzisa ii-emulsions ezisekelwe kwigelatin ngenxa yesisombululo sazo esiphezulu kunye nokuthembeka, nto leyo ebonisa ixabiso layo lobugcisa elihlala lihleli.​
