Digital Low Light Photography: Ho Nka Litšoantšo tse Hlollang ka Maemo a Thata

Mehleng ea kajeno ea dijithale, ho nka lifoto ho se ho fumaneha habonolo ho batho ba bangata ka ho fihla ha li-smartphone le lik'hamera tse tsoetseng pele tsa digital. Ho nka linepe tse bobebe bo tlase ke se seng sa libaka tseo ho buuoang haholo ka tsona tsa ho nka linepe moo baetsi ba lifoto ba nkang litšoantšo tse makatsang maemong a mabone a thata. Ha theknoloji ea dijithale e ntse e tsoela pele, baetsi ba lifoto ba se ba na le lisebelisoa tsa ho nka linepe tse makatsang maemong a bobebe bo tlase.

Ho nka lifoto tse bobebe bo tlase ho kenyelletsa ho nka litšoantšo sebakeng se nang le khanya e fokolang ea tlhaho, joalo ka bosiu kapa tikolohong e lerootho ea ka tlung. Mofuta ona oa ho nka lifoto o tla le liphephetso tse ikhethang, tse kenyelletsang ho se bonahale hantle, lerata le phahameng, le tlhoko ea nako e telele ea ho pepeseha. Leha ho le joalo, ka lisebelisoa le mekhoa e nepahetseng ea digital, lifoto li ka finyella liphello tse tsotehang maemong a tlaase a khanya.

E 'ngoe ea likhatelo-pele tsa bohlokoa tsa ho nka lifoto tse bobebe tse tlase tsa dijithale e bile nts'etsopele ea bokhoni bo phahameng ba ISO lik'hamera tsa dijithale. ISO e bua ka kutlo ea sensor ea khamera ho khanya, 'me litlhophiso tse phahameng tsa ISO li lumella lifoto ho nka litšoantšo maemong a khanya e tlase ntle le ho sebelisa mohloli o mong oa leseli. Ka bokhoni ba ho thunya maemong a holimo a ISO, baetsi ba lifoto ba ka fihlela litšoantšo tse khanyang, tse hlakileng haholoanyane libakeng tse lefifi, ho fokotsa tlhoko ea mabone a maiketsetso.

Ntle le bokhoni bo phahameng ba ISO, lik'hamera tsa dijithale li na le theknoloji e tsoetseng pele ea ho fokotsa lerata e thusang ho fokotsa lerata le lerata la dijithale hangata le bonoang litšoantšong tse bobebe bo tlase. Mekhoa ena ea ho fokotsa lerata e boloka boleng ba setšoantšo le lintlha tse qaqileng esita le maemong a thata a mabone, a lumellang lifoto ho nka litšoantšo tse hlakileng, tse hlakileng libakeng tse nang le khanya e tlaase.

Ho feta moo, tsoelo-pele ea theknoloji ea sensor ea dijithale e ntlafalitse ts'ebetso ea lik'hamera tsa digital maemong a bobebe bo tlase. Lik'hamera tse ngata tsa morao-rao tsa digital li na le li-sensor tse khōloanyane tse tšoarang khanya e eketsehileng le ho hlahisa litšoantšo tsa boleng bo phahameng maemong a tlaase. Ho feta moo, nts'etsopele ea li-sensor tse khanyang ka morao (BSI) e ntlafalitse ts'ebetso ea khanya e tlase ea lik'hamera tsa digital, ho fa lifoto lisebelisoa tsa ho nka litšoantšo tse tsotehang esita le libakeng tse thata ka ho fetisisa tsa mabone.

Lefapheng la ho nka lifoto ka li-smartphone, bokhoni ba khanya e tlase le bona bo ntlafetse haholo lilemong tsa morao tjena. Ka ho kopanya li-algorithms tse tsoetseng pele tsa ts'ebetso ea litšoantšo le ts'ebetso ea Night Mode, lik'hamera tsa smartphone joale li ka hlahisa litšoantšo tse khahlang tse bobebe ntle le tlhoko ea lisebelisoa tse eketsehileng. Tsoelo-pele ena e entse hore ho nka lifoto tse bobebe bo tlase ho fihlellehe ho bamameli ba bangata, ho lumella mang kapa mang ea nang le smartphone ho nka litšoantšo tse khahlang libakeng tse lefifi.

Ka motsoako oa bokhoni bo phahameng ba ISO, thekenoloji ea ho fokotsa lerata le theknoloji e tsoetseng pele ea li-sensor, ho nka lifoto tse tlaase tsa digital ho fetohile tšimo e thabisang le e matla bakeng sa lifoto. Ebang ke ho nka mabone a benyang a toropo bosiu kapa moea o haufi oa lijo tsa mantsiboea tse khantšitsoeng ka likerese, ho nka linepe tse bobebe bo tlase ba dijithale ho fana ka menyetla e sa feleng ea hore baetsi ba lifoto ba hlahlobe le ho bonts'a pono ea bona ea bonono.

Ha theknoloji ea dijithale e ntse e tsoela pele ho fetoha, bokamoso ba ho nka lifoto tse bobebe bo tlase bo bonahala bo khanya ho feta leha e le neng pele, ho fa baetsi ba lifoto lisebelisoa tsa ho sutumelletsa meeli ea boqapi le ho hapa litšoantšo tse makatsang esita le maemong a thata ka ho fetesisa a mabone. Litšoantšo tse makatsang.
