Kuyaziwa kahle ukuthi ukuthatha izithombe eduze lapho ukukhanya kumnyama kakhulu, kungakhathaliseki ukuthi ukukhanya okuphansi namandla okuthwebula izithombe anamandla kangakanani, akukho flash engathathwa, kufaka phakathi i-SLR. Ngakho-ke ocingweni, kubangele ukusetshenziswa kwe-LED flash.

Kodwa-ke, ngenxa yokulinganiselwa kobuchwepheshe bezinto ezibonakalayo, iningi lamathoshi e-LED amanje enziwe ngokukhanya okumhlophe + i-phosphor, okunciphisa ububanzi be-spectral: amandla okukhanya aluhlaza okwesibhakabhaka, amandla okukhanya aluhlaza okwesibhakabhaka nokubomvu mancane kakhulu, ngakho-ke sebenzisa Umbala wesithombe esithathwe yi-flash ye-LED uzophambuka (umhlophe, ithoni ebandayo), futhi ngenxa yamaphutha e-spectral kanye nokwakheka kwe-phosphor, kulula ukudubula amehlo abomvu nokukhanya, futhi umbala wesikhumba uphaphathekile, okwenza isithombe sibe sibi kakhulu, ngisho nangemva "kokuphakanyiswa kobuso" sekwephuzile. Isofthiwe nayo kunzima ukuyilungisa.

Indlela yokuxazulula ifoni ephathekayo yamanje? Ngokuvamile, isisombululo se-flash ye-LED ephindwe kabili enombala ophindwe kabili esisebenzisa ukukhanya okumhlophe kwe-LED okukhanyayo + ukukhanya kombala ofudumele we-LED ukwenza ingxenye ye-spectrum engekho yokukhanya okumhlophe kwe-LED ngokusebenzisa ukukhanya kombala ofudumele we-LED, ngaleyo ndlela kulingisa i-spectrum ecishe ifane ngokuphelele ne-spectrum yemvelo yelanga, okulingana nokuthola ukukhanya kwangaphandle kwelanga kwemvelo kwenza umphumela wokukhanya kokugcwalisa ube ngcono kakhulu, futhi kuqede ukuphambuka kombala we-flash ejwayelekile ye-LED, isikhumba esimpunga, ukukhanya kanye neso elibomvu.

Vele, ngokusungulwa kobuchwepheshe, i-dual-flash enjalo yokushisa enemibala emibili isetshenziswe kabanzi kumafoni ahlakaniphile, futhi ukulungiselelwa okunjalo kusetshenziswe kumafoni ahlakaniphile ngezinga elikhulu.
