Kuyaziwa ukuba ukuthatha imifanekiso kufutshane xa ukukhanya kumnyama kakhulu, nokuba ukukhanya okuphantsi okanye ukukhanya okumnyama kunamandla kangakanani na, akukho flash inokufotwa, kuquka ne-SLR. Ngoko ke kwifowuni, kubangele ukusetyenziswa kwe-LED flash.

Nangona kunjalo, ngenxa yokunqongophala kwetekhnoloji yezinto eziphathekayo, uninzi lweetotshi ze-LED zangoku zenziwe ngokukhanya okumhlophe + i-phosphor, nto leyo ethintela uluhlu lwe-spectral: amandla okukhanya aluhlaza okwesibhakabhaka, amandla okukhanya aluhlaza kunye nobomvu mancinci kakhulu, ngoko ke sebenzisa. Umbala wefoto ethathwe yi-flash ye-LED uya kugqwetheka (umhlophe, ithoni ebandayo), kwaye ngenxa yeziphene ze-spectral kunye nokwakheka kwe-phosphor, kulula ukufota amehlo abomvu kunye nokukhanya, kwaye umbala wesikhumba umhlophe, okwenza ifoto ibe mbi ngakumbi, nangona emva "kokuphakanyiswa kobuso" kutshanje. Isoftware nayo kunzima ukuyilungisa.

Indlela yokusombulula ifowuni ephathwayo yangoku? Ngokubanzi, isisombululo se-LED esiphindwe kabini esinombala okhanyayo osebenzisa ukukhanya okumhlophe kwe-LED + ukukhanya kombala ofudumeleyo we-LED kukwenza inxalenye ye-spectrum engekhoyo yesibane esimhlophe se-LED ngokusebenzisa ukukhanya kombala ofudumeleyo we-LED, ngaloo ndlela kulingisa i-spectrum ephantse ihambelane ngokupheleleyo ne-spectrum yelanga yendalo, elingana nokufumana ukukhanya kwendalo kwangaphandle kwelanga kwenza isiphumo sokukhanya okugcweleyo sibe ngcono, kwaye sisuse ukugqwetheka kombala we-LED flash eqhelekileyo, ulusu olukhanyayo, ukuqaqamba kunye neliso elibomvu.

Kakade ke, ngokuveliswa kweteknoloji entsha, i-dual-flash enjalo yobushushu obunemibala emibini isetyenziswa kakhulu kwiifowuni ezikrelekrele, kwaye ulungiselelo olunjalo lusetyenziswe kwiifowuni ezikrelekrele kakhulu.
