1.Ngaba ilensi enekona ebanzi ifanelekile kwiifoto?

Impendulo idla ngokuba hayi,iilensi ezineekona ezibanzingokubanzi azifanelekanga ukufota imifanekiso. Ilensi ebanzi, njengoko igama lisitsho, inombono omkhulu kwaye ingabandakanya indawo engaphezulu kwifoto, kodwa iya kubangela ukugqwetheka kunye nokuguquguquka kwabalinganiswa abakumfanekiso.

Oko kukuthi, ukusebenzisa ilensi ebanzi ukufota imifanekiso kunokutshintsha iimpawu zobuso zabalinganiswa. Umzekelo, ubukhulu bentloko nomzimba bubonakala bukhulu, kwaye imigca yobuso nayo iya kwandiswa kwaye igqwetheke. Olu ayilokhetho olufanelekileyo lokufota imifanekiso.

Ukuba ufuna ukuthatha imifanekiso, kuyacetyiswa ukuba usebenzise ubude obuphakathi okanye ilensi ye-telephoto ukuze ufumane isiphumo somfanekiso esibonakalayo nesinobukhulu obuthathu. Ngoko ke, yeyiphi ilensi ebanzi efanelekileyo yokudubula?

A ilensi enekona ebanziinobude obufutshane bokugxila, idla ngokuba phakathi kwe-10mm kunye ne-35mm. Umbono wayo mkhulu kunoko iliso lomntu linokukubona. Ifanelekile ukufota ezinye iindawo ezixineneyo, iindawo ezibanzi, kunye neefoto ezifuna ukugxininisa ubunzulu bentsimi kunye nemiphumo yombono.

Umfanekiso wokudubula ngelensi ebanzi

Ngenxa yombono wayo obanzi, ilensi ene-engile ebanzi inokubamba izinto ezininzi, yenze umfanekiso ube mhle kwaye ube nomgangatho ophezulu. Ilensi ene-engile ebanzi inokuzisa izinto ezikude nezikufutshane emfanekisweni, inike umbono wokuvuleka. Ke ngoko, iilensi ezine-engile ebanzi zihlala zisetyenziselwa ukufota izakhiwo, imifanekiso yesitalato sesixeko, iindawo zangaphakathi, iifoto zamaqela, kunye nokufota emoyeni.

2.Umgaqo wokwenza imifanekiso kunye neempawu zeiilensi ezineekona ezibanzi

Ukufotwa kwelensi ene-engile ebanzi kufezekisa isiphumo se-engile ebanzi ngoyilo lwenkqubo yelensi kunye ne-engile yokubonisa ukukhanya (ngokudlulisa ukukhanya kwinkqubo ethile yelensi, indawo ekude ne-axis ephakathi iboniswa kwi-sensor yomfanekiso wekhamera okanye ifilimu), ngaloo ndlela ivumela ikhamera ukuba ibambe umbono obanzi. Lo mgaqo usetyenziswa kakhulu kwiifoto, kwiintengiso nakwezinye iindawo.

Singawuqonda umgaqo wokwenza imifanekiso yeelensi ezinee-engile ebanzi kwezi zinto zilandelayo:

Inkqubo yelensi:

Iilensi ezibanzingokwesiqhelo zisebenzisa indibaniselwano yobude obufutshane befocal kunye neelensi ezinkulu ezinobubanzi. Olu yilo luvumela ilensi ebanzi ukuba iqokelele ukukhanya okungakumbi kwaye ikudlulisele ngokufanelekileyo kwisenzi somfanekiso sekhamera.

Ulawulo lokungahambelani:

Ngenxa yoyilo olukhethekileyo, iilensi ezibanzi zihlala zisengozini yeengxaki zokuphambuka, ezifana nokugqwetheka, ukusasazwa, njl. Ukujongana nale micimbi, abavelisi basebenzisa izixhobo ezahlukeneyo zokukhanya kunye nobuchwepheshe bokugquma ukunciphisa okanye ukuphelisa ezi ziphumo zimbi.

I-engile yoqikelelo:

Ilensi ene-engile ebanzi ifumana isiphumo se-engile ebanzi ngokwandisa i-engile ephakathi kwendawo kunye ne-axis esembindini yelensi. Ngale ndlela, kuya kufakwa indawo engaphezulu kumfanekiso kumgama ofanayo, nto leyo ebonisa indawo ebanzi yokujonga.

Ilensi enekona ebanzi

Kwizicelo ezisebenzayo, kufuneka sikhethe ilensi ebanzi efanelekileyo ngokusekelwe kwiimfuno ezithile zokuthatha imifanekiso kunye nemiboniso. Ngokubanzi, iimpawu zokuthatha imifanekiso zeelensi ezibanzi zezi zilandelayo:

Ukuphazamiseka kwembono:

Xa udubula izinto ezikufutshane ngeilensi enekona ebanzi, kwenzeka ukuphambuka kwendlela obona ngayo izinto, nto leyo ethetha ukuba kumfanekiso othathweyo, izinto ezikufutshane ziya kubonakala zinkulu, ngelixa izinto ezikude ziya kubonakala zincinci. Isiphumo sokuphambuka kwendlela obona ngayo izinto singasetyenziselwa ukudala isiphumo esibonakalayo esikhethekileyo, njengokugqithisela indlela obona ngayo izinto kunye nokugxininisa izinto ezingaphambili.

Imbono ebanzi:

Ilensi ene-engile ebanzi inokubamba indawo ebanzi yokujonga kwaye inokubamba indawo okanye izigcawu ezingaphezulu. Ke ngoko, iilensi ezine-engile ebanzi zihlala zisetyenziselwa ukufota izigcawu ezifana neendawo zomhlaba, izakhiwo, ngaphakathi, kunye nezihlwele ezifuna ukubonisa imvakalelo yendawo ebanzi.

Imiphetho egobileyo:

Iilensi ezineekona ezibanzi zinokuphazamiseka okanye zijijeke, ingakumbi kwiikona ezithe tye nezithe nkqo. Oku kungenxa yokunqongophala kwendalo koyilo lwelensi kwaye ngamanye amaxesha zinokusetyenziselwa ukudala ngabom isiphumo esikhethekileyo okanye ulwimi olubonakalayo.

Ubunzulu obubanzi bentsimi:

Ilensi ene-engile ebanzi inobude obuncinci be-focal, ngoko ke inokuvelisa ubunzulu obukhulu bentsimi, oko kukuthi, zombini indawo engaphambili nengasemva zinokugcina umfanekiso ocacileyo. Le propati yenzaiilensi ezineekona ezibanziiluncedo kakhulu kwiifoto apho kufuneka kugxininiswe khona ubunzulu besiganeko.
