Kodi gelatin ingagwiritsidwe ntchito popanga zithunzi?

Ine.Kufunika kwa Mbiri Yakale​

gelatin Inasintha kwambiri kujambula zithunzi m'zaka za m'ma 1800, m'malo mwa njira zovuta zonyowa. Monga chomangira mu siliva halide emulsions, inagawa mofanana makhiristo owunikira kuwala pa filimu, zomwe zinapangitsa kuti zithunzi zikhale zakuthwa. Kutha kwake kudzaza m'madzi kunathandiza kuti kujambula zithunzi kukhale kosavuta, zomwe zinapangitsa kuti anthu osadziwa zambiri azitha kujambula zithunzi.​

II.Ubwino Waukadaulo​

Gelatin imawongolera kukula kwa makristalo a siliva a halide, zomwe zimakhudza liwiro la filimu ndi kusiyana. Ma emulsions a tirigu wabwino pazithunzi amagwiritsa ntchito kuchuluka kwa gelatin kochepa, pomwe mafilimu othamanga kwambiri amafunikira gelatin yambiri kuti akhazikitse makristalo akuluakulu. Imatetezanso ma emulsions ku kuwonongeka kwa makina ndi chinyezi, zomwe zimapangitsa kuti filimuyo ikhale nthawi yayitali. Ngakhale masiku ano, gelatin imagwirizana ndi mankhwala omwe amakhudzidwa ndi kuwala.

III.Kufunika Kwamakono​

Kujambula zithunzi za digito kunachepetsa kugwiritsa ntchito gelatin, koma imagwirabe ntchito m'njira zina: mapepala osindikizira aluso kwambiri, komwe kapangidwe kake kamawonjezera kuzama kwa chithunzi; ndi makanema osungidwa, omwe amagwiritsidwa ntchito kuti akhale olimba kwa nthawi yayitali. Makampani apadera monga kujambula zithunzi zachipatala (X-rays) amagwiritsabe ntchito ma emulsions ochokera ku gelatin chifukwa cha mawonekedwe awo apamwamba komanso odalirika, kutsimikizira kufunika kwake kwaukadaulo kosatha.​
