Umklamo we-Ergonomic weKhamera Yedijithali
Ukuthuthukiswa kwamakhamera edijithali akunqunywa kuphela yikhwalithi yenzwa, isixazululo, noma amakhono okuqopha ividiyo. Ngaphandle kwezithombe ezibukhali nemibala enembile, kunesici esisodwa esibalulekile esivame ukunquma induduzo yomsebenzisi kanye nokuvumelana ekuthwebuleni: ukwakheka kwe-ergonomic. I-ergonomic yamakhamera edijithali ihlola indlela ukuma, usayizi, isisindo, ukwakheka kwezinkinobho, kanye nokuthungwa kwezinto ezisekela ngayo ukusebenzisana kwabantu okuphephile, okukhululekile, nokusebenza kahle nedivayisi. Ukwakheka kwe-ergonomic kuvumela ikhamera ukuthi izizwe "ivumelana" nesandla, kunciphisa ukukhathala futhi kusize abathwebuli bezithombe ukuba basabele ngokushesha lapho kuvela izikhathi ezibalulekile.
Incazelo ye-Ergonomics ekusetshenzisweni kwekhamera
I-Ergonomics ivela ekuhlanganisweni kwemibono "yomsebenzi" kanye "nemithetho yemvelo yomzimba." Ngokomongo wamakhamera edijithali, i-ergonomics isho ukwakheka okubheka ukwakheka kwesandla, indlela iso elibona ngayo nge-viewfinder noma isikrini, ukuma komzimba lapho uthwebula, kanye nemikhuba yomsebenzisi lapho eshintsha izilungiselelo. Ikhamera ye-ergonomics ivumela abasebenzisi ukuthi bathwebule isikhathi eside ngaphandle kobuhlungu besandla, inciphisa ingozi yokushelela kwekhamera, futhi inciphise amaphutha ngenxa yezinkinobho okunzima ukuzifinyelela.
Umklamo we-ergonomic uphinde usize ekusebenzeni kahle. Abathwebuli bezithombe bavame ukudinga ukushintsha isivinini se-shutter, i-aperture, i-ISO, i-focus, noma imodi yokudubula ngemizuzwana embalwa. Ukuhlelwa okuhle kokulawula kunciphisa isikhathi sokusesha izinkinobho, okuvumela ukunaka ukuthi kuhlale kugxile ekubunjweni kanye nesikhathi.
Ukulinganisela Kokubamba Nokukala Isisindo
Esinye sezingxenye ezibaluleke kakhulu zekhamera yedijithali ukubamba. Ukubamba okuhle kuvame ukuba nomugqa olandela ukuma kweminwe nesandla, futhi kujule ngokwanele ukubamba ikhamera iqine, ikakhulukazi uma usebenzisa amalensi anzima. Kumakhamera e-DSLR, ukubamba kuvame ukuba kukhulu futhi kuvelele ngenxa yomzimba ojiyile. Kumakhamera angenazibuko, inselele iyinkimbinkimbi kakhulu: umzimba uncane kakhulu, kodwa usadinga ukukhululeka ezandleni zabo bonke osayizi.
Ukulinganisela kwesisindo phakathi komzimba nelensi nakho kuthinta induduzo. Ikhamera elula kakhulu kodwa ehambisana nelensi enkulu ingazizwa "iyisicaba" phambili, ibeke ubunzima esihlakaleni. Ngokuphambene nalokho, ikhamera esindayo kakhulu ingakhathaza intamo namahlombe ngokushesha uma ithwalwa isikhathi eside. Abaklami bamakhamera ezimboni balwela ukubeka ibhethri, ibhodi lesifunda, kanye nohlaka lwangaphakathi ukuze isikhungo samandla adonsela phansi sibe seduze nokubamba, okuqinisekisa ukuqina kwekhamera uma ibanjwe ngesandla esisodwa.
Izinto kanye Nokwakheka Komphezulu
Izinto zomzimba wekhamera azigcini nje ngobuhle; zithinta nokuzwakala kwesandla. Irabha enobuthi esibambweni isiza ukuvimbela ukushelela, ikakhulukazi lapho izandla zakho zijuluka noma lapho zidubula emvuleni encane. Amanye amakhamera asebenzisa iziqeshana zesikhumba zokwenziwa noma izembozo ezikhethekile ezivimbela ukushelela. Ezingeni lobuchwepheshe, imizimba ye-magnesium alloy ivame ukukhethwa ngenxa yamandla ayo kodwa nokukhanya okulinganiselwe, kuyilapho amakhamera asezingeni lokuqala evame ukusebenzisa i-polycarbonate engabizi kakhulu.
Ukuthungwa kwenkinobho nakho kubalulekile. Izinkinobho ezinezindawo ezahlukene—isibonelo, inkinobho yokucisha evelele futhi ebushelelezi—zisiza abasebenzisi ukuthi babone izilawuli ngokuthinta nje, ngaphandle kokubheka. Lokhu kuwusizo ikakhulukazi lapho bedubula ekukhanyeni okuphansi noma ezimweni ezidinga izimpendulo ezisheshayo.
Inkinobho kanye nesakhiwo sokudayela
Ukwakheka kwekhamera yesimanje kunqunywa kakhulu ngokubeka izinkinobho nama-dial. Umgomo ukufinyelela okusheshayo ngokunyakaza okuncane. Ngokuvamile, izinkinobho ezibalulekile zifakwa eduze kwesithupha nomunwe wokukhomba, njengoba le minwe emibili inokuguquguquka okukhulu.
Ama-dial amakhulu nawesibili avame ukutholakala eduze kwenkinobho yokushutha noma ngemuva ukuze kulungiswe ukuvezwa. Amakhamera e-Ergonomic aklanyelwe ukuvumela izinguquko zokusetha ngenkathi ugcina iso lakho ku-viewfinder. Amanye amakhamera afaka i-joystick yokuhambisa ngokushesha iphuzu lokugxila. Le joystick ijwayelekile kumakhamera amaningi aphakathi nendawo kanye nasezingeni eliphezulu, njengoba ivumela ukukhetha okusheshayo kokugxila ngaphandle kokudinga ukunyakaza okukhulu kweminwe.
Ngaphezu kwalokho, ukuba khona kwezinkinobho ezenziwe ngokwezifiso kuthuthukisa i-ergonomics. Abasebenzisi bangenza ngezifiso imisebenzi ngokwezidingo zabo—isibonelo, ukwenza i-eye autofocus isebenze, ukushintsha i-metering, noma ukubiza ama-preset athile—okwenza imisebenzi isebenze ngendlela yomuntu siqu futhi isebenze kahle.
Isikrini, Isitholi Sokubuka, kanye Nokuxhumana Okubonakalayo
Induduzo yokubuka nokudubula nayo iyingxenye ye-ergonomics. Kokubili i-electronic viewfinder (EVF) kanye ne-optical viewfinder (OVF) kufanele kubekwe kahle ukuze kuvinjelwe ukukhungatheka kwentamo. Izinkomishi zamehlo ezithambile zinganciphisa ingcindezi endaweni yamehlo. Kubathwebuli bezithombe abagqoka izibuko, ibanga lokukhululeka kwamehlo liyinto ebalulekile okufanele icatshangelwe ngoba lithinta ukuthi uhlaka lonke lungabukwa yini.
Isikrini se-LCD esicacile noma esitshekile sisiza abasebenzisi ukuthi bathathe izithombe besuka ema-engeli aphansi, ama-engeli aphezulu, noma lapho beqopha ama-vlog. Ngokombono we-ergonomic, isikrini esiguquguqukayo sivimbela abasebenzisi ukuthi bagobe noma baphakamise izingalo zabo phezulu kakhulu. Ngaphezu kwalokho, isikhombikubona sesikrini sokuthinta esiphendulayo singasheshisa ukukhetha ukugxila noma izilungiselelo zemenyu, yize izinkinobho ezibonakalayo zisadingeka ezimweni ezithile, njengalapho ugqoke amagilavu.
Imenyu kanye nesistimu yokuxhumana
I-Ergonomics ayigcini nje ngesimo somzimba, kodwa futhi ihlanganisa nokwakheka kwemenyu okunengqondo. Amamenyu aminyene, amagama adidayo, noma izilungiselelo ezifihliwe zingakhathaza abasebenzisi ngengqondo ngokushesha. Ikhamera ye-ergonomic inemenyu ehlelekile, izithonjana ezicacile, inketho ethi "Imenyu Yami" noma "Izintandokazi", kanye nesibonisi solwazi esilula ukusifunda.
Amamenyu asheshayo nawo ayisici esibalulekile. Ngenkinobho eyodwa, abathwebuli bezithombe bangafinyelela amapharamitha ayisihluthulelo ngaphandle kokudinga ukuzulazula kumamenyu amade. Lokhu kusindisa isikhathi futhi kunciphisa ingozi yokuphuthelwa yisikhashana.
Izici Zosayizi Wesandla Nokuhlukahluka Komsebenzisi
Akuwona wonke umuntu onesandla esifanayo. Ngakho-ke, umklamo ofanele we-ergonomic uvumela abasebenzisi abaningi, kusukela ezandleni ezincane kuya kwezinkulu. Abanye abakhiqizi banikeza izesekeli ezengeziwe njengezibambo zebhethri noma izithupha zokuphumula ukuze kuthuthukiswe induduzo. Izibambo zebhethri azigcini nje ngokwandisa amandla kodwa futhi zinikeza ukubamba okuqondile okuzinzile lapho kuthwetshulwa izithombe.
I-Ergonomics ibheka nabasebenzisi abanezidingo ezikhethekile. Isibonelo, izinkinobho ezincane kakhulu noma ezisondelene kakhulu zingaba nzima kubasebenzisi abanokukhubazeka kokunyakaza. Umklamo olula ukuwusebenzisa uzocabangela isikhala phakathi kwezinkinobho futhi unikeze impendulo ecacile yokuthinta.
I-Ergonomics Yezitayela Ezihlukene Zokuthatha Izithombe
Izidingo ze-ergonomic zingahluka ngohlobo lwezithombe. Abathwebuli bezithombe bezemidlalo nezilwane zasendle badinga izilawuli ezisheshayo, izinkinobho zokugxila okulula ukuzifinyelela, kanye nomzimba ozinzile onelensi ende ye-telephoto. Abathwebuli bezithombe basemgwaqweni bavame ukubeka phambili ikhamera encane, eyimfihlo, futhi ekhululekile ukuyiphatha usuku lonke. Abathwebuli bezithombe badinga inkinobho yokurekhoda efinyeleleka kalula, ukubamba okuzinzile, kanye nesikrini esisekela ukubuka kusuka kuma-engeli amaningi.
Ngakho-ke, akukho mklamo ofanela bonke. Ikhamera "engcono kakhulu" ngokwe-ergonomic yileyo efanelana kahle nezidingo zomsebenzisi kanye nemikhuba yakhe yokusebenza.
Isiphetho
Umklamo wekhamera yedijithali oqondile uyinhlanganisela yokwakheka komzimba, ingqondo yomsebenzisi, ubunjiniyela bezimboni, kanye nezidingo zokuzijwayeza ukuthatha izithombe. Ukubamba okukhululekile, ibhalansi efanele yesisindo, izinto ezingasheleli, ukuhlelwa kwezinkinobho okusebenzayo, isitholi sokubuka esiguquguqukayo kanye nesibonisi, kanye namamenyu okulula ukuwaqonda konke kuthinta kakhulu isipiliyoni sokuthwebula. I-ergonomics enhle ayigcini nje ngokwenza ikhamera ibukeke kahle; ithuthukisa ukulawula, inciphisa ukukhathala, futhi isiza abathwebuli bezithombe ukuthi bathwebule izikhathi ngokuzethemba okwengeziwe.
Ekugcineni, ukukhetha ikhamera akufanele kusekelwe kuphela ezicini zobuchwepheshe. Zama ukuyibamba, usebenzise izinkinobho zayo, bese ubona ukuthi iyasisekela yini isitayela sakho sokuthwebula. Ngoba ezweni lokuthwebula izithombe, induduzo kanye nesivinini kuvame ukunquma ukuthi umzuzu uthwetshulwe kahle noma umane uphuthelwe.
