I. ijambo
Irangi ryerekana irangi: bivuga umubare ushobora gushyirwa muburebure bwa santimetero imwe; igice: PDI
Ubwinshi bwa optique: bivuga ingano ya feza yagabanutse muri firime ya emulsiyo, ni ukuvuga ubushobozi bwo guhagarika urumuri, igice ni "D", formula: D = lg (ingufu zumucyo wabaye / ingufu zumucyo zanduye)
Gamma: Gamma bivuga urwego ubwinshi bwa optique ya firime mbi ihinduka nyuma yo gukorerwa ubukana butandukanye bwurumuri?
II. Ibigize n'imikorere ya firime yo gushushanya
Igice cyo hejuru:
Ifite uruhare mukurinda gushushanya kandi ikingira umunyu wa feza emulsion yangiritse!

2.Ikinyobwa cyibiyobyabwenge (silver umunyu emulsion layer)
Mubishusho, ibice byingenzi bigize emulioni ni bromide ya silver, chloride ya silver, iyode ya silver nibindi bintu byumunyu wumunyu wa feza, hamwe na gelatine na pigment bishobora kugarura centre yibanze ya feza ikoresheje urumuri. Ariko umunyu wa feza ntushobora gushonga mumazi, gelatine rero ikoreshwa kugirango ihindurwe ihagaritswe kandi isizwe hejuru ya firime. Pigment muri emulsion igira ingaruka zikangura.
3. Igice gifatika
Teza imbere gufatira kumurongo wa emulsion kuri base ya firime. Kugirango tunoze imbaraga zihuza hagati ya emulsion na firime ya firime, igisubizo cyamazi ya gelatine na chrome alum ikoreshwa nkigice cyo guhuza kugirango gihuze neza.
4. Polyester shingiro
Abatwara firime ishingiro hamwe na firime mbi muri rusange bakoresha nitrocellulose, acetate cyangwa polyester base. Ubwoko bubiri bwa mbere bwibanze bwa firime bufite ihinduka ryinshi, kandi ingano ya firime ya polyester irahagaze neza
5. Anti-halo / static layer
Amashanyarazi arwanya halo na static. Mubihe bisanzwe, hejuru yubuso bwa firime yerekana amafoto azagaragaza urumuri, bigatuma urwego rwa emulsion rwongeye gukangurirwa kubyara halo. Kurinda halo, igisubizo cyamazi ya gelatine wongeyeho fuchsin yibanze ikoreshwa mugutwikira inyuma ya firime kugirango ikuremo urumuri. Yitwa anti-halation layer.

III, inzira yo gukora firime yo gushushanya
1. Gushushanya byoroheje
Gushushanya urumuri mubyukuri ni inzira yoroheje. Filime imaze gushyirwa ahagaragara, umunyu wa feza ugarura centre ya feza, ariko muriki gihe, nta shusho ishobora kugaragara kuri firime, yitwa ishusho yihishe. Imashini zikoreshwa cyane zikoreshwa ni: imashini-yerekana imashini ishushanya urumuri, Imbere yimbere yubwoko bwa laser yumucyo, ubwoko bwinyuma bwubwoko bwa laser, nibindi.
2. gutera imbere
Umunyu wa feza nyuma yo kumurikirwa uhinduka ibice bya feza byirabura. Ubushyuhe bwuwitezimbere bugira uruhare runini kumuvuduko witerambere. Ubushyuhe buri hejuru, niko umuvuduko witerambere wihuta. Ubushyuhe bukwiye bwiterambere ni 18 ℃ ～ 25 ℃. Ibice byingenzi bigize igicucu cyamazi bigizwe niterambere, kurinda, kwihuta na inhibitor. Imikorere yayo niyi ikurikira:
1) .Iterambere: Igikorwa cyuwitezimbere ni ukugabanya umunyu wa feza wunvikana kuma feza. Imiti ikunze gukoreshwa nkigabanya imiti irimo hydroquinone na p-cresol sulfate.
2). Umukozi urinda: Umukozi urinda abuza uwatezimbere okiside, kandi sodium sulfite ikoreshwa kenshi nkumurinzi.
3) .Umuvuduko: Kwihuta nikintu cya alkaline umurimo wacyo nukwihutisha iterambere. Byihuta bikoreshwa cyane ni sodium karubone, borax, hydroxide ya sodium, nibindi, muri byo hydroxide ya sodium niyihuta cyane.
4). Inhibitor: Uruhare rwa inhibitor ni ukubuza kugabanya umunyu wa feza woroshye kuri feza, bishobora kubuza igice kitamurika kubyara igihu mugihe cyiterambere. Potasiyumu bromide ninzitizi nziza, kandi ifite imbaraga zikomeye zifotora Ahantu harabujijwe intege nke, kandi ahantu hafite intege nke zumucyo birakomeye.

IV. Gukosora
Koresha amonium thiosulfate kugirango ukureho umunyu wa feza utagabanijwe kuri feza, bitabaye ibyo iki gice cyumunyu wa feza kizongera kugaragara, gisenya ishusho yumwimerere.
