I-Spectrum Egcwele kanye ne-Infrared Photography

Ngaphandle Kokubonakala: Isethulo Sezithombe Ezigcwele Ze-Spectrum Ne-Infrared

Ukuthatha izithombe, emnyombweni wako, kuwubuciko bokuthwebula ukukhanya. Kodwa kuthiwani uma ukukhanya esikubonayo kuyingxenyana nje yendaba? Ukuthwebula okugcwele kwe-spectrum ne-infrared kusimema ukuthi sidlulele ngale kwemikhawulo yombono womuntu namakhamera ethu ajwayelekile, okuveza izwe elifihliwe lobuhle be-ethereal nemininingwane yesayensi. Lezi zindlela, ezihlanganisa ukuthwebula ubude bamaza okukhanya okungabonakali ngeso lenyama, ziguqula izigcawu ezivamile zibe imibono engavamile. Kochwepheshe bokudala namabhizinisi aphethe amaphrojekthi ayinkimbinkimbi, lokhu kunwetshwa kokubuka kuyisingathekiso esinamandla. Njengoba nje ikhamera elungisiwe ingadalula idatha engabonakali, i-OS yebhizinisi eyimojula efana ne-Mewayz ingakhanyisa imininingwane efihliwe nokugeleza komsebenzi, iguqule ulwazi olungahluziwe lube isithombe esicacile, esingasetshenzwa.

Ukubona Okungabonakali: Isayensi Yokukhanya Okushintshiwe

Amakhamera edijithali ajwayelekile afakwe isihlungi, esibizwa ngokuthi isibuko esishisayo, esivimba ukukhanya kwe-ultraviolet (UV) kanye ne-infrared (IR) ukuze kukhiqizwe izithombe ezifana nokubona kwethu komuntu. Ukuthwebula okugcwele kwe-spectrum ne-infrared kudinga ukulungisa le hardware. Ukuguqulwa kwe-spectrum okugcwele kuhilela ukususa lesi sihlungi sangaphakathi, okuvumela inzwa yekhamera ukuthi ithwebule uhla olukhulu lwamaza amaza—kusuka ku-ultraviolet, ku-spectrum ebonakalayo, kanye nokujula ku-infrared. Ukuze bese uhlukanisa amabhendi athile, abathwebuli bezithombe banamathisela izihlungi zangaphandle. Isihlungi se-infrared-pass, ngokwesibonelo, sivimba konke ukukhanya okubonakalayo, sivumela ubude beza beza be-IR kuphela ukuthi bushaye inzwa, sidale izithombe ezifanekisela iphupho lapho amahlamvu acwebezela abe mhlophe nesibhakabhaka siba mnyama.

"Ukuthwebula izithombe nge-infrared akubonisi nje umhlaba ngendlela ehlukile; kukubonisa umhlaba ohlukile ngokuphelele. Kwembula impilo yezitshalo, ukuthungwa kokukhanya, kanye nezindawo ezilele ngaphansi kwelanga esingenakulibona."

Izinhlelo Zokudala Nezisebenzayo

Ukusetshenziswa kwalobu buchwepheshe kusuka kubuciko obumsulwa kuya ekuhlaziyeni okubalulekile. Ngobuchule, ukuthwebula izithombe kwe-infrared kwaziwa ngobuhle bako be-surreal, bamanye amazwe, okukwenza intandokazi yobuciko obuhle, imfashini, kanye nezindawo ezivusa inkanuko. "I-Wood Effect" ibangela uhlaza olucebile nge-chlorophyll ukuthi lubonise ukukhanya kwe-IR ngokukhazimulayo, okunikeza amaqabunga aluhlaza abe mhlophe ngokukhazimulayo. Emikhakheni engokoqobo, ukuthwebula izithombe kwe-spectrum okugcwele kubalulekile. Isetshenziswa kusayensi yezobunhloli ukuze kwembule ubufakazi obufihlekile, ekubuyiseleni ubuciko ukubona ngaphansi kwezingqimba zopende, kwezolimo ukuze kuhlolwe impilo yezitshalo, nasekuhloleni izakhiwo ukuze kutholwe umonakalo wamanzi noma ukuvuza okushisayo. Leli khono lokukhipha idatha ethile ku-spectrum yokukhanya lifana nendlela inkundla efana ne-Mewayz evumela ngayo ibhizinisi ukuthi lihlunge futhi lihlaziye ukusakazwa kwedatha ethile kusukela ekusebenzeni kwalo, liguqule ulwazi olunamandla lube ubuhlakani obuqondisiwe, obuwusizo.

Igiya Elibalulekile Lokuqalisa

Ukungena kulo mkhakha kudinga okokusebenza okubalulekile nokucatshangelwa. Akusona nje isihlungi osigoqa kulensi yakho; iqala ngokuguqulwa kwekhamera.

• Ukuguqulwa Kwekhamera: Isinyathelo esibaluleke kakhulu. Lokhu kuhilela ukususa ngokomsebenzi isihlungi sangaphakathi se-IR-cut yekhamera. Ungakhetha ukuguqulwa okugcwele kwe-spectrum (okuguquguquka kakhulu) noma ukuguqulwa okuzinikele kwe-infrared (isb., 720nm) ukuze uthole ukubukeka okuthile.
• Izihlungi Zangaphandle: Ukuze uthole amakhamera e-spectrum agcwele, isethi yezihlungi (UV, IR, njll.) iyadingeka ukuze kuhlukaniswe ubude begagasi. Kumakhamera aguqulelwe yi-IR, isihlungi sakhelwe ngaphakathi.
• Ukucatshangelwa Kwelensi: Amanye amalensi angabangela "ama-hotspots" (izindawo ezikhanyayo ezingezona ezemvelo) ku-IR. Ukucwaninga ukuhambisana kwamalensi kubalulekile.
• Ukucubungula Ngemva: Izithombe ze-IR ngokuvamile zidinga ukulungiswa kwebhalansi emhlophe ngokwezifiso kanye nokushintshaniswa kwesiteshi kusofthiwe efana ne-Adobe Photoshop ukuze kuzuzwe ukubukeka kwemibala engamanga yakudala noma ama-monochrome ahlanzekile.

Ukuveza Umbono Omusha Ngomhlaba Wakho

I-spectrum egcwele nezithombe ze-infrared zishintsha kakhulu ubudlelwano bethu nendawo ezungezile, zibhale amandla angabonakali kanye nokusebenzisana okulolonga iqiniso lethu. Kumculi, kuyisango lokubonisa okuhlukile. Kusosayensi noma umhloli, ithuluzi elibalulekile lokuxilonga. Lesi simiso sokwembula izendlalelo ezifihliwe namaqiniso okusebenza siyisisekelo ekusebenzeni kahle kwebhizinisi lesimanje. Ukuphatha amaphrojekthi wokudala anezinhlangothi eziningi noma ukugeleza komsebenzi wokuhlaziya kudinga isistimu engenza yonke ingxenye ibonakale ngokucacile. Ngale ndlela, ukuhlola i-spectrum egcwele yokukhanya kuhambisana nesidingo sokusebenzisa i-spectrum ephelele yedatha yebhizinisi lakho—into ebanzi, ne-modular OS efana ne-Mewayz eklanyelwe ukuyifeza, iqinisekisa ukuthi akukho ukuqonda okubalulekile okusala ethunzini.
