Njengoba sonke sazi,ilensi ye-telecentricuhlobo lwelensi ekhethekile yezimboni eyenzelwe ukusetshenziswa kokubona komshini. Akukho mthetho oqinile wokukhetha kwayo, futhi kuncike kakhulu ekutheni ingahlangabezana yini nezidingo zokudubula.
Kanjani ukukhetha ilensi ye-telecentric? Yiziphi izinto okufanele zicatshangelwe?
Ngokuvamile, ngaphambi kokukhetha ilensi ye-telecentric, izici ezilandelayo zidinga ukucatshangelwa:
Ubude be-focal kanye nensimu yokubuka
Kuyadingeka ukukhetha ubude obufanele bokugxila kanye ne-Engela yensimu ngokuya ngezidingo zangempela zokusetshenziswa kanye nosayizi nezici zethagethi. Ubude obude bokugxila bunganikeza ukucaca okuphezulu kanye nemininingwane, kuyilapho ama-engela amakhulu ensimu angamboza indawo ebanzi.
Ubude be-focal lens ye-telecentric ngokuvamile buphakathi kuka-17mm no-135mm, futhi ukukhetha ubude be-focal kuncike kakhulu kulokho ohlose ukukuthatha. Abathwebuli bezithombe ze-landscape bangadinga ubude be-focal obubanzi, kuyilapho abathwebuli bezithombe bezakhiwo bangadinga okungaphezu kuka-35mm.
Ukukhetha ubude bokugxila kwezithombe ezahlukene
Ikhwalithi yokukhanya
Khethailensi ye-telecentricngenqubo yokuklama nokukhiqiza okubonakalayo kwekhwalithi ephezulu ukuqinisekisa ukucaca nokunemba kwesithombe esibukwayo. Ikhwalithi yokubonakalayo ifaka phakathi izinto zelensi, ubuchwepheshe bokumboza, inkomba yokukhanya kwezingxenye zelensi nokunye.
Usayizi wembobo
Usayizi wembobo uthinta ukusebenza kwelensi ezindaweni ezinokukhanya okuphansi kanye nokulawulwa kokujula kwesizinda. Ngokuvamile, imbobo engu-f/2.8 noma ngaphezulu ifaneleka kakhulu ukusetshenziswa ezindaweni ezimnyama, kanti imbobo engu-f/4 noma encane ifaneleka kakhulu ukusetshenziswa ezindaweni ezikhanyayo.
Umphumela wobukhulu bembobo ekudubuleni
Umklamo kanye nesakhiwo
Cabanga ngomklamo kanye nezici zesakhiwo seilensi ye-telecentric, njengohlelo lokulungisa ingxenye egxile, uhlelo lokulungisa ukugxila, ukumbozwa kwelensi neminye imisebenzi. Ukwakheka kanye nesakhiwo salezi zici kuzothinta ngqo ukusebenziseka kalula kanye nomphumela wokubuka kwelensi ye-telecentric.
Isabelomali kanye nezidingo zangempela
Uma ukhetha ilensi ye-telecentric, udinga futhi ukulinganisa izici ezahlukahlukene ngokuya ngesabelomali sakho kanye nezidingo zangempela zokubuka. Amanye amalensi e-telecentric angabiza kakhulu, kodwa anganikeza imiphumela yokubuka engcono; Kunemikhiqizo ethile engabizi maqondana nokusebenza futhi intengo nayo ingaba ukukhetha okuhle. Ngokuvamile kunconywa ukukhetha imikhiqizo engabizi ngaphansi kwesisekelo sokuhlangabezana nesidingo.
Umkhiqizo kanye nensizakalo
Imikhiqizo ehlukene ingathinta ukusebenza kanye nekhwalithi yelensi. Ngaphansi kwezimo ezivamile, ukukhetha imikhiqizo eyaziwayo kanye nedumela elihleilensi ye-telecentricimikhiqizo ingaqinisekisa ikhwalithi yomkhiqizo kanye nensizakalo yangemva kokuthengisa. Amanye amabhrendi anganikeza iziqinisekiso zesikhathi eside noma abe nezikhungo zokulungisa ezigunyaziwe kakhulu.
Imicabango Yokugcina:
Ngokusebenzisana nochwepheshe eChuangAn, kokubili ukuklama kanye nokukhiqiza kuphathwa onjiniyela abanekhono eliphezulu. Njengengxenye yenqubo yokuthenga, ummeleli wenkampani angachaza ngokuningiliziwe ulwazi oluthile mayelana nohlobo lwelensi ofisa ukuyithenga. Uchungechunge lwemikhiqizo yelensi kaChuangAn lusetshenziswa ezinhlobonhlobo zezicelo, kusukela ekuqapheni, ekuskeneni, kuma-drones, ezimotweni kuya emakhaya ahlakaniphile, njll. I-ChuangAn inezinhlobo ezahlukene zamalensi aqediwe, angashintshwa noma enziwe ngezifiso ngokwezidingo zakho. Xhumana nathi ngokushesha okukhulu.
