Ukukhanya, kusebenza imifanekiso ye-HDR evela ku-Ubuntu

Imifanekiso I-HDR (imifanekiso ephezulu yoluhlu) Beza njengokujija ingcamango yesiko lokufota. Iimodeli ezintsha zekhamera zibandakanya izixhobo zokubamba iifoto ezininzi zesifundo esinye ngokuchasana okwahlukileyo (okubizwa ngokuba yi "bracketing"). Banokuqhubekeka nokwenza ezi foto kwaye babuyisele umfanekiso ophakamileyo oguqukayo kuwe ngaphandle kokwenza nantoni na. Ndicinga ukuba kuzakubakho iselfowuni enokuyenza, andazi. Inyani yile yokuba i-HDR ikhona, ke indlela elula yokusebenza nale mifanekiso ikwakhona kwiLinux. Kungenxa yoko le nto iLuminance HDR yaphuhliswa.

Ukukhanya ngumboniso wamagqala kangangokuba ubenalo nexesha lokutshintsha igama lakhe, Phambi kokuba yaziwe njenge «Qtpfsgui». Ngethamsanqa abaqulunqi bayo babenombono osempilweni wokuyinika igama elinobuntu ngakumbi. Ndishiya apha eyakho iphepha elisemthethweni.

Ukukhanya kwe-HDR 2.5.1 Luhlobo lwamva nje oluzinzileyo lwenkqubo. Le yokugqibela yinguqulelo ye-bugfix kunye nophuculo oluncinci kwiinguqulelo zangaphambili.

Olunye utshintsho olusizisela le nguqulo yamva lulandelayo:

• Umbundu wamanqanaba ohlengahlengiso uphuculwe kwaye wenza ukuba ukhetheke.
• Yongeza inqaku lokudibanisa ngokuzikhethela.
• Ukukhangela umfanekiso opheleleyo.
• Ngoku ungajonga amaxwebhu kwi-intanethi.

Ukuba umntu ufuna ukwazi ukuba zeziphi ezinye iindaba eziza kusinika olu hlobo lutsha, banokujongana noku kulandelayo unxibelelwano.

Iifomathi ezixhaswe yiLuminance HDR

I-Luminance HDR yinkqubo (esekwe kwizixhobo ze-Qt5) ebonelela umsebenzisi nge Umsebenzi opheleleyo wemifanekiso ye-HDR. Le nkqubo ixhasa ezi fomathi ze-HDR zilandelayo: I-OpenEXR (exr), iifomathi zeTiff: i-16 bits, i-32 bits kunye ne-LogLuv (tiff) kunye neefomathi zemifanekiso eluhlaza phakathi kwabanye. Ikwaxhasa iJPEG, iPNG, iPPM, iPBM. Ungajonga zonke iifomati ezixhaswayo kwiwebhusayithi yayo okanye kwinkqubo ngokwayo.

Ukufakwa kweLuminance HDR

Singayifaka le nkqubo kwiinguqu ezahlukeneyo zoBuntu; ukusuka kwi-16.04, 16.10, 17.04 kunye neziphumo zazo. Kwakhona kwiwebhusayithi yayo unokukhuphela usetyenziso kwezinye iinkqubo zokusebenza, ezinje ngeWindows okanye iMac OS. Zonke zingama-64-bit.

Ukuqhubeka nofakelo lweBuntu siza kuvula i-terminal ngokucinezela iCtrl + Alt + T okanye ukukhangela "iTheminali" kwinkqubo yeDash. Emva koko kufuneka ulandele la manyathelo alandelayo:

Kuqala siza kongeza indawo ehambelana nayo ukuyikhuphela. Senza umthetho wokongeza indawo yokugcina iPPA:

sudo add-apt-repository ppa:dhor/myway

Njengamaxesha onke, inkqubo iya kusicela ukuba sibhale iphasiwedi yomlawuli.

Ukuba besele sinenguqulo yangaphambili efakiweyo, sinokwazisa isiHlaziyi seSoftware (uMlawuli woHlaziyo) kwaye siyivuselele ngokulula. Ukuba akunjalo, siyaqhubeka nofakelo ngokwenza le miyalelo ilandelayo yokuhlaziya indawo yokugcina kunye nokufaka i-HDR yeLuminance:

sudo apt update && sudo apt install luminance-hdr

Nje ukuba ukufakwa kugqityiwe, sinokuyiqhuba ngokukhangela kwinkqubo yeDash.

Isicelo ngokwaso sibonisa ukusebenza ngokulula. Ifuna impumelelo ebonakalayo ibhalansi enzima phakathi kweemfuno zabasebenzisi abaphambili kunye nokusetyenziswa ngokulula ukuze uqalise ngenkqubo. Isiphumo yinkqubo ethi, ukuba igqibelele kwaye igcwele ukhetho, inakho yenza imifanekiso ye-HDR ngemizuzwana ngonqakrazo olumbalwa.

Khipha i-HDR yeLuminance

Indawo yokugcina i-PPA ingasuswa kwiiNkqubo zeNkqubo -> iSoftware kunye noHlaziyo-> Ezinye iiNkqubo. Singawusebenzisa lo myalelo ulandelayo, oya kuthi ususe isoftware efakiweyo kunye nokucoca iiphakheji eseleyo:

sudo add-apt-repository -–remove ppa:dhor/myway  && sudo apt -–purge remove luminance-hdr && sudo apt autoremove

Ukugqiba, cacisa ukuba le nkqubo akunjalo Photoshop ni Gimp. Kufuneka sihlale sikhumbula ukuba kulo mbandela wokufota eyona nto ibalulekileyo ifoto ngokwayo kunye nendlela yokuyithatha, ngaphezulu kwesoftware esisebenzisa imifanekiso kuyo. NgeLuminance kuya kufuneka ukhathalele ukuba iifoto zethu zihambelana kakuhle, ke kulula ukuba uthathe imifanekiso usebenzisa i-tripod.

Isishwankathelo, uLuminance yenye inkqubo ekufuneka ibeyinxalenye yesixhobo seLinux ukuba siyakuthanda ukuthatha imifanekiso.
