Web and Social Media Optimization

Konzani zithunzi zanu kuti zigawidwe pa digito popanda kusiya zomwe mukuziganizira:

Gwiritsani ntchito makonda amtundu wa JPEG pakati pa 70-85% pamlingo wabwino kwambiri wa kukula kwake
Ganizirani za WebP kuti tsamba lanu liwonjezere nthawi yotsitsa
Sinthani zithunzi kukhala miyeso yoyenera malinga ndi mawonekedwe ake
Gwiritsani ntchito ma JPEG opita patsogolo kuti muzitha kutsitsa bwino
Chotsani metadata yosafunikira kuti mutsegule mwachangu (koma sungani zambiri zaumwini)
Dziwani kukhathamiritsa kwapapulatifomu (Instagram, Facebook, etc.)
Gwiritsani ntchito ma CDN amakono omwe amatha kukhala ndi mawonekedwe okongoletsedwa kutengera chithandizo cha msakatuli

Metadata Management

Konzani bwino metadata yazithunzi pamawonekedwe osiyanasiyana:

Onjezani kukopera ndi zambiri zolumikizirana ndi zithunzi zonse zomwe zagawidwa
Gwiritsani ntchito mawu osasinthika kuti mufufuze bwino m’mabuku anu
Dziwani kuti mitundu ina imasunga ma metadata ambiri kuposa ena
Phatikizani ndi data yamalo a malo ndi zithunzi zapaulendo ngati kuli koyenera
Lembani zambiri zaukadaulo zomwe zingakhale zothandiza pokonzanso mtsogolo
Ganizirani zachinsinsi mukagawana zithunzi ndi data yamalo ophatikizidwa
Mvetsetsani momwe mapulogalamu osiyanasiyana amagwirira ntchito metadata panthawi yosintha mawonekedwe

Mafunso Omwe Amafunsidwa Kawirikawiri Okhudza Mafayilo Azithunzi

Kodi ndiyenera kuwombera mumtundu wa RAW nthawi zonse?

Ngakhale RAW imapereka mawonekedwe apamwamba komanso kusinthasintha kosintha, sikofunikira nthawi zonse. RAW ndiyabwino pantchito yaukadaulo, zovuta zowunikira, kapena pakafunika kuwongolera kopitilira muyeso. JPEG ikhoza kukhala yokwanira kujambula wamba, nthawi yomwe mukufuna kuwombera mosalekeza, kukhala ndi malo ochepa, kapena mukufuna kugawana nawo mwachangu. Akatswiri ambiri amagwiritsa ntchito RAW+JPEG kuti akhale ndi njira zonse ziwiri.

Chifukwa chiyani mitundu yanga imawoneka yosiyana ndikagawana zithunzi pa intaneti?

Kusiyana kwamitundu pa intaneti kumatha kuchitika pazifukwa zingapo: kusintha kolakwika kwa malo (osasintha kukhala sRGB kuti mugwiritse ntchito intaneti), kusowa mbiri yamitundu yophatikizidwa, kasamalidwe kamitundu yosiyanasiyana ya asakatuli, mawonekedwe osiyanasiyana owonetsera, komanso kuphatikizika ndi kukonza kwamasamba ochezera. Kuti muchepetse zovutazi, nthawi zonse tembenuzirani ku malo amtundu wa sRGB, lowetsani mbiri yamitundu, gwiritsani ntchito mapulogalamu omwe ali ndi kasamalidwe koyenera, ndikuwona zithunzi zanu pazida zingapo musanagawane.

Kodi pali kusiyana kotani pakati pa kuponderezana kotayika ndi kopanda kutaya?

Kuphatikizika kosataya kumachepetsa kukula kwa fayilo osataya chithunzi chilichonse, kulola kukonzanso kwabwino kwa chithunzi choyambirira (zitsanzo: PNG, TIFF yokhala ndi compression ya ZIP). Kuphatikizika kotayika kumataya zonse zazithunzi kuti mukwaniritse kukula kwa mafayilo ang’onoang’ono (zitsanzo: JPEG, WebP mumayendedwe otayika). Lossless ndi yabwino kwa mafayilo ogwirira ntchito ndikusunga, pomwe kutayika ndikoyenera kutumizidwa komaliza ngati kukula kwa fayilo kuli kofunikira. Kusiyana kwakukulu ndikuti kukanika kotayika sikungasinthidwe kuti mubwezeretse deta yoyambirira.

Kodi ndisinthe mafayilo anga a RAW kukhala mtundu wa DNG?

Kutembenuzira ku DNG kuli ndi maubwino angapo: kugwirizanitsa kwanthawi yayitali ngati mulingo wotseguka, makulidwe ang’onoang’ono a mafayilo osatayika, ma metadata ophatikizidwa omwe safuna mafayilo am’mbali, ndikuchita mwachangu mu pulogalamu ya Adobe. Komabe, pali zoganizira: kutembenuka kumatenga nthawi, deta yokhudzana ndi kamera ikhoza kutayika, ndipo si mapulogalamu onse omwe amathandiza DNG mokwanira. Ojambula ambiri amasintha kukhala DNG pazosunga zakale pomwe amasunga mafayilo oyambira a RAW ngati zosunga zobwezeretsera.

Kodi njira yabwino yosindikizira zithunzi zanga ndi iti?

Pakusindikiza kwaukadaulo, TIFF nthawi zambiri imatengedwa ngati mtundu wabwino kwambiri chifukwa imasunga mtundu wonse komanso imathandizira kuya kwa mitundu 16 ndi malo osiyanasiyana amitundu. Kwa ma laboratory azithunzi ogula, JPEG yapamwamba (90-100% khalidwe) nthawi zambiri imakhala yokwanira komanso yovomerezeka kwambiri. Pokonzekera mafayilo osindikizira, gwiritsani ntchito Adobe RGB color space for wider gamut, onetsani kusamvana koyenera (300 PPI is standard), ndipo onani zofunikira za ntchito yanu yosindikiza chifukwa zingakhale ndi zokonda kapena zolepheretsa.

Kodi ndimakonza bwanji zithunzi za tsamba langa popanda kutayika bwino?

Kuti muwongolere zithunzi zapaintaneti ndikusunga zomwe zimawoneka bwino: sinthani kukula kwazithunzi kukhala miyeso yeniyeni yomwe ikufunika (musadalire kukulitsa kwa osatsegula), gwiritsani ntchito JPEG pamtundu wa 70-80% pazithunzi, lingalirani mawonekedwe a WebP akusakatula amakono, gwiritsani ntchito PNG pazithunzi zokhala ndi mawu kapena kuwonekera, khazikitsani zithunzi zomvera ndi makulidwe angapo, gwiritsani ntchito ma CDN amakono okhathamiritsa, ndikuwongolera zithunzi zamasiku ano. Zida monga ImageOptim, Squoosh, kapena ShortPixel zingathandize kupeza bwino pakati pa khalidwe ndi kukula kwa fayilo.

Kodi pali kusiyana kotani pakati pa zithunzi za 8-bit ndi 16-bit?

Kuzama pang’ono kumatanthauza kuchuluka kwa chidziwitso chamtundu chomwe chasungidwa pa tchanelo chilichonse pachithunzi. Zithunzi za 8-bit zimasunga milingo 256 pa tchanelo chilichonse (mitundu yotheka 16.7 miliyoni), pomwe zithunzi za 16-bit zimasunga milingo 65,536 panjira (mamiliyoni amitundu yotheka). Ubwino wothandiza wa 16-bit ndi wosalala bwino komanso kusinthasintha kokulirapo kusanachitike bandi kapena posterization. Gwiritsani ntchito 16-bit posintha komanso pamafayilo apamwamba, makamaka posintha kwambiri mawonekedwe, mtundu, kapena kamvekedwe. Pomaliza kutumiza, 8-bit nthawi zambiri imakhala yokwanira chifukwa zida zambiri zowonetsera zimatha kuwonetsa mtundu wa 8-bit.

Kodi ndingasungire bwanji zithunzi zanga motetezedwa kwazaka zambiri?

Kusungirako nthawi yayitali: sungani mafayilo oyambirira a RAW / DNG ndi ambuye osinthidwa (TIFF / PSD), gwiritsani ntchito mitundu yambiri yosungiramo (ma drive akunja, kusungirako mitambo, archival optical media), gwiritsani ntchito njira yosungiramo 3-2-1, kuyendetsa sitolo kumalo olamulidwa ndi nyengo, fufuzani nthawi zonse kukhulupirika kwa archive ndi ma checksums, kusamukira ku mtundu watsopano wa zaka zosungirako NG5 (FFD) lowetsani metadata yokwanira (kukopera, mawu osakira, mafotokozedwe), sungani dongosolo lamakalata, ndikulemba gulu lanu losungira kuti mudzazigwiritse ntchito mtsogolo. Kutsimikizira nthawi zonse ndi kusamuka ndikofunikira chifukwa zonse zosungirako zimawonongeka pakapita nthawi.

Yang’anirani Ntchito Yanu Yojambula

Kumvetsetsa mafayilo amafayilo ndi gawo limodzi chabe lazithunzi. Onani maupangiri athu ena owonjezera kuti mukweze luso lanu ndikusintha mayendedwe anu kuchokera pakujambulidwa mpaka kusindikiza.
