Iyini i-HDR?
I-HDR (i-High Dynamic Range) Kuyisu elisetshenziswa ekuthwebuleni ukuze kugqanyiswe imininingwane emithunzini nakumaphuzu avelele esithombe. Ivumela abathwebuli bezithombe ukuthi bathwebule uhla olubanzi lwamathoni okukhanya nombala, benqoba imikhawulo yekhamera.
Inqubo ye-HDR isuselwe ekuthatheni izithombe ezimbalwa zesigcawu esifanayo ngokuchayeka okuhlukile: esivamile, esingavezwanga ngokwanele, kanye nesivezwe ngokweqile. Lezi zithombe zibe sezihlanganiswa kusofthiwe yokuhlela izithombe ukuze kwakhiwe isithombe esisodwa esiqukethe yonke imininingwane yezithombe ezintathu zangempela.
Shayela>Ukusetshenziswa kwe-HDR Kumakhamera Edijithali
Amakhamera esimanje edijithali, okuhlanganisa nama-smartphone, anomsebenzi wokuthatha izithombe ze-HDR. Uma ukhetha imodi ye-HDR, ikhamera ithatha ngokuzenzakalelayo izithombe eziningi emazingeni okuchayeka ahlukene bese izihlanganisa ukuze idale isithombe se-HDR.
Ukusebenzisa isici se-HDR kungaba usizo ezimeni lapho kunomehluko omkhulu phakathi kwezindawo ezikhanyayo nezimnyama, njengalapho uthwebula ukushona kwelanga, indawo yangaphakathi ekhanyiswe ngokwemvelo, noma izigcawu ezihluke kakhulu. Nokho, kubalulekile ukukhumbula ukuthi akuzona zonke izimo ezizuzayo ekusetshenzisweni kwe-HDR.
Ungazithatha kanjani izithombe nge-HDR
Ukuthwebula izithombe nge-HDR akuyona inkimbinkimbi, kodwa ezinye izinto eziyisisekelo ziyadingeka ukuze uthole imiphumela engcono kakhulu. Nazi ezinye izinyathelo zokuthatha isithombe nge-HDR:
- Thola indawo enebanga eliphezulu lokukhanya nezithunzi.
- Setha ikhamera yakho kumodi ye-HDR.
- Thatha isithombe. Ikhamera yakho izoqoqa izithombe ezimbalwa ezinamaleveli ahlukene okuchayeka.
- Ikhamera noma isofthiwe yokucubungula izohlanganisa izithombe zenze isithombe se-HDR.
Izinzuzo kanye Nemibi ye-HDR
I-HDR inezinzuzo eziningi; ivumela imininingwane eyengeziwe ezindaweni ezimnyama nezigqamile, ihlinzeka ngokubukeka okungokoqobo ezithombeni, futhi ingasiza ukuthuthukisa ikhwalithi yezithombe ezithathwe ngaphansi kwezimo zokukhanya ezifanele.
Kodwa-ke, kuphinde kube nokubi njengoba i-HDR ingaholela ezithombeni ezibukeka zigcwele ngokweqile noma zokwenziwa uma zisetshenziswa ngokungalungile. Ukwengeza, i-HDR ayisebenzi kahle ezimeni ezihamba ngokushesha, njengoba izithombe ezithathwe ekuchaweni okuhlukene zingahle ziqondaniswe ngokungeyikho.
I-Postproduction Techniques ku-HDR
Ingxenye enkulu yempumelelo ekuthwebuleni izithombe ze-HDR ivela ekucutshungulweni kokuthunyelwe. Usebenzisa izinhlelo zokuhlela izithombe ezifana ne-Adobe Photoshop noma i-Lightroom, ungasebenzisa ukulawula okwengeziwe kokuthi isithombe sokugcina sihlangana kanjani. Amathuluzi angemuva kokukhiqiza avumela ukulungiswa okuhle kokugqamayo, ukukhanya, kanye nemininingwane kokubekwe obala kanye nezibani eziphansi.
Umkhuba omuhle awukona ukwenza ihaba ngezilungiselelo ze-HDR, zama ukuthola umphumela obukeka ungokwemvelo. Njenganoma iyiphi enye indlela yokuthatha izithombe, isihluthulelo sempumelelo nge-HDR ukuzilolonga nokuhlola izigcawu nezimo ezahlukahlukene.
