Guhindagurika ni ibintu bitazibagirana mu ifatwa ry'amashushoindorerwamo z'amaso. Impinduka zikunze kugaragara zirimo ihindagurika rya chromatic, ihindagurika ry’umubumbe, ihinduka ry’imiterere y’inyuma, ihindagurika ry’imiterere y’ubutaka, no kugorama.
Ubwoko bw'amakosa agaragara cyane butandukana bitewe n'imiterere y'urumuri, umuntu ufatwa, n'ibisabwa mu miterere y'amashusho atandukanye. Gusobanukirwa no kwiga uburyo bwo kwirinda amakosa mu mashusho atandukanye bishobora kongera cyane ireme ry'ishusho.
Hasi aha, turasuzuma ibisubizo byo kwirinda ikosa rishingiye ku kurasa ahantu hatandukanye n'ibyo bakeneye byihariye:
1.Amafoto y'amafoto
Amafoto agaragara nk'ikintu gisobanutse neza, inyuma hadasobanutse neza, n'imiterere y'umubiri karemano. Umucyo ukoreshwa ushobora kuba usanzwe cyangwa uw'ubukorano. Impinduka zikunze kubaho zirimo imiterere y'uruziga, koma, guhindagurika, no guhinduka kw'urumuri.
Ubusanzwe gufotora amashusho bisaba umwanya munini kugira ngo hakorwe bokeh, ariko iyi nayo ni impamvu ikomeye yo guhinduka kw'uruziga. Iyo ukoresheje lens ifite inguni nini, guhagarika guhagarara inshuro 1-2, nko guhindura F2.8 ukajya kuri F4, bishobora kunoza cyane guhinduka kw'uruziga no kugorama k'umurima.
Irinde gukoresha lenzi zifite inguni nini cyane ku mashusho yegereye cyangwa igice cy'umubiri. Mu gihe ukoresha lenzi ifite inguni nini ku mashusho yuzuye, gerageza gushyira hagati y'umuntu (cyane cyane amaso) mu gitereko, kure y'impande.
Byongeye kandi, ni ngombwa kwirinda ko umusatsi cyangwa ingohe by'umuntu bireba neza ahantu hafite urumuri rukomeye. Amatara akomeye yo gusubiza inyuma azongera imiterere y'urumuri ihagaze neza ndetse n'uburangare.
Ushobora gukoresha amatara yo ku ruhande hamwe n'urumuri rwuzuye kugira ngo ugabanye itandukaniro riri hagati y'ikintu n'inyuma. Niba hari urumuri rw'inyuma inyuma, irinde kurishyira ku nkengero z'ishusho kugira ngo ugabanye ingaruka za koma.

2.Amafoto yo gufotora ahantu nyaburanga
Amafoto yo gufotora ahantu nyaburanga arangwa n'aho agaragara cyane, kuba akeneye ishusho yuzuye, ahantu henshi hatandukanye cyane, ndetse n'urumuri rusanzwe (urumuri rwinshi ku manywa n'urumuri ruto nijoro). Harimo guhindagurika, kugorama kw'ubutaka, kugorama kw'amashusho, kugorama kw'umubumbe, no kuruhuka.
Ku mafoto asanzwe yo ku manywa, guhagarika uwo mwobo kuri F8-F11 bizagabanya ihindagurika ry’umubumbe, ihindagurika rya chromatic, no kugorama k’umurima, bitume ishusho yose irushaho kuba nziza. Irinde gukoresha uwo mwobo ntarengwa cyangwa utwobo duto cyane, nka F16 no munsi yawo, kuko ibi bizatera ihindagurika ry’umubumbe, bigabanye ubukana, kandi bigatera amashusho n’ihindagurika ry’umubumbe.
Iyo urasa inyubako ifite ultra-lenzi ifite inguni nini, shyira imbere lens zo gushushanya zifite inguni nini cyane kugira ngo urebe neza ko imirongo yubatswe igororotse n'inkombe z'amashusho zityaye. Mu gihe utunganya, shyira imbibi zifite itandukaniro rinini (nk'impande cyangwa imiterere y'imisozi) hagati cyangwa hagati y'ishusho, kure y'inkombe zihenze cyane, kugira ngo ugabanye ihindagurika ry'impande. Gukoresha agakoresho ko gushushanya lens bishobora gukumira urumuri rukomeye ku ifoto y'lens, bigagabanya ihindagurika ry'ishusho n'ihindagurika ry'ishusho.
Mu gihe ufata amashusho mu kirere nijoro, shyira imbere gukoresha lensi nini ifite angle yagutse cyane kugira ngo ugenzure neza imiterere y'inyenyeri; irinde gukoresha uburyo ntarengwa bwo gufata amashusho ya zoom kugira ngo ufate amashusho mu kirere nijoro, kuko bizatuma ugaragara cyane.
Kwibanda ku budashira no gushyira inyenyeri hagati mu ishusho bishobora kugabanya inyenyeri zikurikiraho bitewe na koma. Niba hari uduce tw'amabara ku nyenyeri, koresha uburyo bwo gukosora icyerekezo cya chromatic muri kamera kugira ngo uhagarike icyerekezo cya chromatic mbere y'igihe.
Gukoresha tripod na cable release mu gihe cyo gufata amashusho bishobora gukumira ubukana bw'urusaku ruterwa no gutigita kwa kamera no kutumvikana. Zimya kugabanya urusaku kuri kamera yawe igihe kirekire, kuko kugabanya urusaku kuri bamwe mu banyamideli bishobora gukanda amakuru no kongera ubusumbane; kugabanya urusaku muri porogaramu bishobora gukoreshwa mu gutunganya amashusho nyuma yo kuyatunganya.

3.Amafoto ya macro
Gufotora amashusho macro birangwa n'ikintu kidahinduka, urumuri rugenzurwa, no gushaka ishusho isobanutse neza. Ariko, ibintu bishobora guhinduka, nko kugorama kw'uruziga, kugorama k'umurima, kutagira ishusho isobanutse, no kugorama kw'urumuri, birushaho kwiyongera mu bihe bya macro.
Ku mafoto macro, ni byiza gukoresha lens ya macro yihariye, ikoreshwa mu gufotora hafi kandi igakosora imiterere y'aho ibintu biherereye n'impinduka. Ugereranyije no gukoresha backlight cyangwa zoom lens mu kongera ubwiza,amatara maninibigabanya cyane kugoreka no guhinduka kw'amashusho.
Hagati aho, gufotora macro bisaba ubujyakuzimu buto cyane bw'ubutaka, akenshi bisaba umwanya muto kugira ngo haboneke ubukana buhagije kandi binafasha kugabanya ubusumbane. Ariko, hakwiye kwitabwaho ingaruka zo gukwirakwiza, zishobora gusaba guhuza uburebure bw'ubutaka. Ni byiza gushyira imbere lenses macro zifite imiterere ya apochromatic kugira ngo zihagarike ubusumbane bwa chromatic mu buryo bw'amashusho.
Byongeye kandi, gukoresha urumuri rworoshye bishobora kugabanya itandukaniro ry'amabara ku mpande z'ikintu zigaragaza itandukaniro rikomeye; mugihe ureba, hitamo agace ko hagati k'ishusho, hanyuma ushyire umutwe w'ingenzi w'ifoto hagati y'ishusho uko bishoboka kose kugira ngo ugabanye ingaruka zo guhinduka k'inkombe; ku buzima busanzwe bw'imiterere minini, ushobora gukoresha uburyo bwo kwibanda ku gice kugira ngo usubize ikibazo cyo kugabanuka k'inkombe bitewe n'impinduka z'aho ureba.

4.Ubwubatsi n'iimberepgushushanya
Amafoto y’ubwubatsi arangwa no gukurikirana imirongo y’ubwubatsi igororotse, ibipimo nyabyo, n’ibisobanuro birambuye mu ishusho yose. Amatara ashobora kuba asanzwe cyangwa ay’ubukorano, kandi ashobora guhinduka nko kugorama, kugorama k’ubutaka, kugorama k’amashusho, no kugaragara nk’aho ari astigmatism.
Indorerwamo zo mu bwoko bwa Tilt-shift ni zo zikundwa cyane mu gufotora inyubako. Zishobora gukosora burundu uburyo bwo kugena aho ibintu biherereye no kugena aho ibintu biherereye binyuze mu guhindura cyangwa kugena aho ibintu biherereye, mu gihe zikuraho uburyo bwo kuzenguruka aho ibintu biherereye, zigatuma hagati n'impande z'ishusho bingana, bityo hirindwa ko imiterere y'imbere y'ishusho ihinduka bitewe n'uburyo bwo kureba aho ibintu biherereye.
Gukoresha uburyo bwa ultra-lenzi ifite inguni niniishobora gufata umwanya, ariko ikunze kugorama mu mwanya wayo. Mu gihe ufata indorerwamo y'inguni nini, ni byiza guhagarika umwobo wo kumanuka kuri F8-F11 kugira ngo ugabanye imiterere y'aho uherereye n'ihindagurika rya chromatic.
Mu gihe ufata amashusho y’inyubako uhereye hasi cyangwa hejuru, gerageza gufata kamera ijyanye n’umurongo w’inyubako kugira ngo ugabanye uburyo bwo kureba amashusho. Niba bidashoboka gufata amashusho y’inyubako, ibikoresho byo gukosora amashusho bishobora gukoreshwa mu gutunganya amashusho nyuma yo kuyakoresha.
Mu gihe ushushanya amashusho y’inyubako, menya neza ko imirongo y’ingenzi y’inyubako (nk’inkuta n’amadirishya) iteganye n’umupaka w’amadirishya kugira ngo hirindwe ko imirongo igaragara ku nkengero z’ishusho.
Koresha amatara yoroshye mu gufotora inyubako zo mu nzu kugira ngo ugabanye uburangare buterwa n'urumuri ruto, ariko kandi ugabanye itandukaniro ry'ibirahure/icyuma no gukumira ubusumbane bwa chromatic. Ku mafotora y'inyubako zo hanze, shyiramo agapfundikizo k'indorerwamo kugira ngo wirinde ko urumuri rwinshi rukura mu ndorerwamo.

5.Inyamaswa zo mu gasozi nasibyambupgushushanya
Amafoto y’inyamaswa zo mu gasozi na siporo ahanini akoresha lenzi za telephoto. Aho hantu harangwa no kugenda kw’umuntu ku muvuduko mwinshi, bisaba gukurikirana byihuse, kandi urumuri rushobora kuba rukomeye cyangwa ruto. Ibibazo bikunze kugaragara byo guhindagurika birimo koma, astigmatism, chromatic aberration, na spherical aberration.
Mu gihe urasa inyamaswa zo mu gasozi/siporo, shyira imberelenzi za telefotohamwe n'ibintu bidakwirakwira cyane kugira ngo bihagarike neza ihindagurika rya chromatic. Mu rumuri rwinshi rwo hanze, guhagarika umwanya wo guhagarara inshuro 1-2, urugero, kuva kuri F2.8 kugeza kuri F4, bishobora kongera cyane ubukana bw'imbere n'impande, gukumira koma na astigmatism, no kunoza uburyo autofocus ikora neza.
Mu gihe ufata amashusho mu mikino mu rumuri ruto kandi ugasaba umwanya munini, hitamo umwanya wa kabiri mu bushobozi bwa lens (nka F2.8). Iyo ubaye muri koma, hagarara kuri F3.5 kugira ngo uhuze uburyo bwo gufata urumuri n'uburyo bwo kugabanya urumuri. Gukoresha uburyo bwo gukurikirana ubwiyongere bwa kamera mu muvuduko mwinshi bituma ikomeza kwibanda ku kintu kigenda, bigabanye uburangare bw'ubwiyongere buterwa n'ibibazo bitagaragara.
Byongeye kandi, gukoresha agakoresho ko gufata lensi ya telephoto + tripod / monopod bishobora kugabanya gutigita kwa lensi no kwirinda astigmatism iterwa no gutigita; gushyiraho agakoresho ko gukingira lensi bishobora gukumira izuba ritaziguye gukubita lensi iyo urasa hanze, bigabanye urumuri n'impinduka; iyo urasa inyoni mu biguruka/zigenda vuba, gerageza kuzuza igice cyo hagati cy'ishusho n'ikintu kugira ngo ugabanye ingaruka zo gutigita kwa lensi.
Mu gusoza, kugira ngo wirinde ibibazo byo guhindagurika kw'indorerwamo z'amabara, ugomba kubanza gusobanukirwa indorerwamo z'amabara ukoresha. Buri ndorerwamo ifite ubushobozi bwo gukora neza. Gerageza indorerwamo yawe mbere y'igihe kugira ngo umenye uburebure bw'indorerwamo cyangwa aho guhindagurika kw'amabara bigaragara cyane, kandi uyirinde cyane mu gihe cyo gufata amashusho.
Ni ngombwa kumenya ko gukosora amakosa agaragara mu mucyo (guhitamo lens, guhagarika aperture, guhindura axis y'urumuri) ari ingenzi, mu gihe kwishyura nyuma yo gutunganya ari inyongera gusa; gutunganya cyane nyuma yo gutunganya bizatuma ishusho itaboneka neza.
