I-Luminance, isebenza ngezithombe ze-HDR kusuka ku-Ubuntu

Izithombe I-HDR (izithombe ezinobubanzi obuphezulu) Beza njengokusonteka kumqondo wendabuko wokuthwebula izithombe. Izinhlobo ezintsha zekhamera zifaka amadivayisi wokuthwebula izibhamu eziningana zendaba efanayo ngokudalula okuhlukile (okubizwa nge- "bracketing"). Bangakwazi ukucubungula lezi zithombe futhi bakunikeze isithombe esisezingeni eliphezulu esinamandla ngaphandle kokwenza lutho. Ngicabanga ukuthi kuzoba khona neselula engayenza, angazi. Iqiniso ukuthi i-HDR ikhona, ngakho-ke indlela elula yokusebenza nalezi zithombe nayo kufanele ibe khona kwiLinux. Kungakho i-Luminance HDR yathuthukiswa.

ILuminance ingumbukiso omakadebona kangangokuba ize yaba nesikhathi sokushintsha igama layo, ngaphambi kwaziwa njenge «Qtpfsgui». Ngenhlanhla abadali bayo babenombono onempilo wokuyinika igama elinobuntu ngokwengeziwe. Ngishiya lapha eyakho ikhasi elisemthethweni.

I-Luminance HDR 2.5.1 Yinguqulo yakamuva ezinzile yohlelo. Lesi sakamuva yinguqulo ye-bugfix enokuthuthuka okuncane kunezinguqulo zangaphambilini.

Ezinye zezinguquko ezisilethela le nguqulo yakamuva yilezi ezilandelayo:

• Umkhawulo wamazinga wokulungisa usuthuthukisiwe futhi wenziwa wakhetha.
• Kungezwe ukufakwa kwesici ngokuzithandela.
• Ukuzulazula kwesithombe esigcwele.
• Manje usungabheka imibhalo online.

Uma othile efuna ukwazi ukuthi yiziphi ezinye izindaba le nguqulo entsha ezosinikeza zona, angaxhumana nokulandelayo isixhumanisi.

Amafomethi asekelwa yi-Luminance HDR

I-Luminance HDR wuhlelo (olususelwa kuthuluzi lamathuluzi le-Qt5) elihlinzeka umsebenzisi ngefayela le- ukusebenza okugcwele kwezithombe ze-HDR. Lolu hlelo lusekela amafomethi we-HDR alandelayo: i-OpenEXR (exr), amafomethi we-Tiff: ama-bits angama-16, ama-bits angama-32 kanye ne-LogLuv (tiff) namafomethi wesithombe samaRaw phakathi kwabanye. Ibuye ihambisane ne-JPEG, PNG, PPM, PBM. Ungahlola wonke amafomethi asekelwayo kuwebhusayithi yayo noma ohlelweni uqobo.

Ukufakwa kwe-Luminance HDR

Singakwazi ukufaka lolu hlelo ezinhlotsheni ezahlukahlukene ze-Ubuntu; kusuka ku-16.04, 16.10, 17.04 kanye nokuphuma kwawo. Futhi kwiwebhusayithi yayo ungalanda uhlelo lwezinye izinhlelo zokusebenza, njengeWindows noma iMac OS. Zonke zingama-64-bit.

Ngokuqhubeka nokufakwa kwe-Ubuntu sizovula i-terminal ngokucindezela i-Ctrl + Alt + T noma ukusesha i- "Terminal" ku-Dash yesistimu. Ngemuva kwalokho kufanele ulandele lezi zinyathelo ezilandelayo:

Okokuqala sizokwengeza indawo ehambelana nayo ukuyilanda. Sisebenzisa umyalo wokufaka okugciniwe kwe-PPA:

sudo add-apt-repository ppa:dhor/myway

Njengenjwayelo, uhlelo luzosicela ukuthi sibhale iphasiwedi yethu yomlawuli.

Uma ngabe besivele sifake inguqulo yangaphambilini, singavula iSoftware Updater (Isiphathi Sokuvuselela) bese siyivuselela kalula. Uma kungenjalo, siyaqhubeka nokufaka ngokusebenzisa imiyalo elandelayo ukuvuselela amakhosombe nokufaka i-Luminance HDR:

sudo apt update && sudo apt install luminance-hdr

Lapho ukufakwa sekuqediwe, singakuqalisa ngokukufuna kuDash yesistimu.

Isicelo uqobo sikhombisa ukusebenza okulula. Ifuna ngempumelelo enengqondo ibhalansi enzima phakathi kwezidingo zabasebenzisi abaphambili nokusebenziseka kalula ukuze uqalise ngohlelo. Umphumela wuhlelo okuthi, uma luphelele futhi lugcwele izinketho, lungakwazi izithombe ze-HDR ngemizuzwana ngokuchofoza izinkinobho ezimbalwa.

Khipha i-Luminance HDR

Indawo yokugcina ye-PPA ingasuswa ku-System Settings -> Software ne-Updates -> Ezinye Izinhlelo. Singasebenzisa futhi umyalo olandelayo, nawo ozosusa isoftware efakiwe bese uhlanza amaphakheji asalile:

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

Ukuqedela, cacisa ukuthi lolu hlelo akunjalo Photoshop ni I-Gimp. Kumele futhi sikhumbule njalo ukuthi kulolu daba lokuthatha izithombe into ebalulekile isithombe uqobo nendlela yokuthatha, okungaphezu kwesoftware esisebenza ngayo izithombe. Nge-Luminance kufanele uqaphele ukuthi amashothi ethu aqondaniswe kahle, ngakho-ke kulula ukuthatha izithombe usebenzisa i-tripod.

Ngokufingqa, i-Luminance olunye uhlelo okufanele lube yingxenye ye-arsenal yethu ye-Linux uma sithanda ukuthatha izithombe.
