Isizathu sokuba Ufuna ukulinganisa umlenze wakho
I-Gamma yintsebenziswano engaxilwanga ekusebenziseni ikhowudi kwaye ihlaziya imilinganiselo yokukhazimula kwiimifanekiso eziqhubekayo nezihambayo. Isetyenziselwa ukucacisa ukuba ixabiso leenombolo zepikseli libhekiselele ekugqibeleni kwayo.
Nangona i-gamma kunzima kakhulu ukuyiqonda ngokubanzi, kubalulekile ukuba abafoto bezedijithali baqonde ukuba kusebenza njani kwimifanekiso. I-Gamma ithintela kakhulu indlela umfanekiso wesitrajethi ubheka kwikhompyutheni yekhompyutha.
Ukuqonda iGamma kwi-Photography
I-gamma yegama isebenza kwimigangatho yefoto xa sifuna ukujonga imifanekiso kwi-ordinators. Ingqiqo ibalulekile ukuqonda (nangona nje ephezulu) kuba injongo kukukwenza umfanekiso wesigodi okhangeleka kakuhle kangangoko kunokwenzeka kwi-monitor and uncalibrated surveillance.
Kukho iintlobo ezintathu ze-gamma ezibandakanyeka kwimifanekiso yezedijithali:
- Imifanekiso yeGamma - Isetyenziswe yikhamera okanye isofthiwe yokuguqula umfanekiso we- RAW ukuguqula umfanekiso kwifayile ecindezelweyo (JPG okanye iTIFF).
- Bonisa i-Gamma - Isetyenziswe ngabahloli bekhompyutha kunye namakhadi evidiyo ukuze ulungelelanise imveliso yomfanekiso. I-gamma ephezulu yokubonisa izakudala imifanekiso ebonakala ibumnyama kwaye ihluke ngakumbi.
- I-Gamma ye-System - Ebizwa nangokuthi 'ukubukela i-gamma,' oku kubonakaliswe kuyo yonke imilinganiselo ye-gamma esetyenziselwa ukubonisa umfanekiso: ngokukodwa, umfanekiso kwaye ubonise i-gammas ehlangeneyo. Ngokomzekelo, umfanekiso ofanayo ujongwa kwi-esweni kunye neembonakaliso ezahlukeneyo ze-gamma aziyi kubonakala efanayo kuba 'ukubuka i-gamma' kuhluke.
Ukuvela kwiKhamela yokujonga: Indlela iGamma isebenza ngayo
I-pixel ngayinye kwisithombe somdijithali inikwe ixabiso elinqumle izinga layo lokukhanya. Iliso lekhompyutheni lisebenzisa le miqobo xa ibonisa imifanekiso yezedijithali. Nangona kunjalo, i-CRT kunye ne- LCD zekhompyutheni zimele zisebenzise la maxabiso ngendlela engafanelekanga, oku kuthetha ukuba ixabiso kufuneka lihlonyelwe ngaphambi kokuba luboniswe.
Ukuchaneka ngaphandle kwebhokisi, umboniso wekhompyutha udla ngokuba ne-gamma ye-2.5. Uninzi lweekhamera ze-DSLR zidubula ngendawo yombala we-sRGB okanye i-Adobe RGB kwaye isebenza kwi-gamma ye-2.2.
Ukuba ikhompyutheni yekhompyutheni ayinakulinganiswa ukufana nale 2.2 i-gamma ngoko imifanekiso evela kwi-DSLR ibonakala ibumnyama kwaye ihluke ngokupheleleyo imifanekiso idutshulwa kwindawo yokuqala!
Kutheni i-Monitor Calibration ibalulekile?
Kuzo zonke ezi zizathu isethi yemigangatho isetyenziswe ukwenzela ukuba umfanekiso kweso siqhamo uza kubonakala njengomfanekiso ofanayo kumlindi wakho. Le nkqubo ibizwa ngokuba yi- calibration kwaye isetyenziselwa ukufumana uvavanyo oluthile lwe-gamma olufana nolunye uvavanyo olulinganiselweyo kwihlabathi.
Akukho mfufti-zithombe, nokuba ingaba ngumtsalane okanye oyingcali, kufuneka asebenze ngemifanekiso ngaphandle kokujonga ilanga. Kutyalo-mali oluncinci oluya kuqinisekisa ukuba zonke iifoto ozibelana nge-intanethi okanye ukuthumela kwi-lab yebhile yokuprintwa ibonakala ngendlela oyihlose ngayo. Akunakulungile ukudala umfanekiso okhangeleka kuwe kwaye ukhangeleka kumntu wonke!
Unokusebenzisa iindlela ezahlukeneyo zokulinganisela umlindo wakho, kubandakanywa i-hardware kunye neenketho zekhompyutha.
Umsebenzisi oqhelekileyo wekhompyutheni akakwazi ukulinganisela umlindo wabo. Oku kungabangela inkinga kubafoto bezithombe abazama ukubonisa (okanye ukuthengisa) imifanekiso yabo. Nangona kunjalo, ukuba iliso lakho lilinganiselwe, ngoko wenze okusemandleni akho ukubonisa imifanekiso yakho ngendlela engcono kakhulu. Eyona nto ingcono ongayenza kukuba uchaze ukulinganisela kunoma yimuphi umbonisi obona umfanekiso 'omnyama' okanye 'okhanya kakhulu.'
