Magic wand - imodzi mwa zipangizo zamakono mu Photoshop. Mfundo yogwirira ntchito ikuphatikizapo posankha ma pixels a mtundu wina kapena mtundu mu fano.
Kawirikawiri, ogwiritsa ntchito omwe sakudziwa zomwe ali nazo ndi zofunikira za chidachi amakhumudwa ndi ntchito yake. Izi zikuchitika chifukwa chowoneka kuti n'zosatheka kuteteza kusankha kwa mtundu kapena mtundu winawake.
Phunziroli lidzakumbukira kugwira ntchito ndi "Wachiphamaso". Tidzaphunzira kuzindikira zithunzi zomwe timagwiritsa ntchito chidachi, komanso kuti tizisintha.
Mukamagwiritsa ntchito Photoshop version CS2 kapena poyamba, "Wokongola" Mungathe kusankhapo pokhapokha pangoyang'ana pazithunzi zake pamanja pomwe. Muyeso la CS3, chida chatsopano chikuwonekera, chotchedwa "Posankha mwamsanga". Chida ichi chimayikidwa mu gawo lomwelo ndipo mwachindunji chikuwonetsedwa pa baru yanyumba.
Ngati mumagwiritsa ntchito maofesi a Photoshop pamwamba pa CS3, ndiye kuti mumasintha pazithunzi "Posankha mwamsanga" ndipo mundandanda wotsika pansi mupeze "Wokongola".
Choyamba tiyeni tione chitsanzo cha ntchito Magic Wand.
Tiyerekeze kuti tili ndi chithunzi choterocho ndi mzere wodutsa monochromatic:
Chidachi chimalowa mu malo osankhidwawo ma pixelini omwe, malinga ndi Photoshop, ali ndi liwu lomwelo (mtundu).
Pulogalamuyi imatsimikizira mtundu wa digito wa mitundu ndi kusankha malo ofanana. Ngati malowa ndi aakulu kwambiri ndipo ali ndi monochromatic fill, ndiye mu nkhaniyi "Wokongola" zofunikira kwambiri.
Mwachitsanzo, tifunikira kuwonetsa malo a buluu m'chithunzi chathu. Zonse zomwe zikufunika ndi kodinkhani botani lamanzere lamanzere pamalo alionse a buluu. Pulogalamuyi idzadziŵika bwino mtengo wa pulogalamuyo ndikuyendetsa ma pixel ofanana ndi mtengo umenewu kumalo osankhidwa.
Zosintha
Kupirira
Ntchito yapitayi inali yophweka, chifukwa chiwembucho chinadzazidwa ndi monochromatic, ndiko kuti, panalibe mithunzi ina ya buluu pamzere. Kodi chidzachitike ndi chiyani ngati tigwiritsira ntchito chida ichi kumbuyo?
Dinani pa malo a imvi pa gradient.
Pachifukwa ichi, pulogalamuyi inadziwika mitundu yosiyanasiyana yomwe imakhala yamtengo wapatali ku tsamba lomwe ife tazilemba. Mtundu uwu umatsimikiziridwa ndi makonzedwe a zipangizo, makamaka "Kuleza Mtima". Chikhazikitso chiri pazitsulo chapamwamba.
Izi zimasankha momwe zingatipangire zingati zosiyana (mfundo yomwe tazijambula) kuchokera mumthunzi umene udzasungidwa (yowonekera).
Kwa ife, mtengo "Kuleza Mtima" ikani ku 20. Izi zikutanthauza kuti "Wokongola" onjezerani kusankhidwa kwa 20 kumeta mdima ndi kuwala kuposa chitsanzo.
Zithunzi mu fano lathu zimaphatikizapo masentimita 256 a kuwala pakati pa mdima wakuda ndi woyera. Chidachi chikuwonetsedwa, molingana ndi zoikidwiratu, masitepe 20 ofunika muzolowera zonsezo.
Tiyeni, chifukwa cha kuyesera, yesetsani kuonjezera kulekerera, kunena, 100, ndikugwiritsanso ntchito "Wokongola" ku gradient.
Ndi "Kuleza Mtima"Zowonjezereka kasanu (poyerekeza ndi zomwe zapitazo), chida chikusonyeza malowa kawiri kawiri, popeza sizinthunzi 20 zomwe zinawonjezeredwa ku mtengo wa mtengo, koma 100 mbali iliyonse ya kuwala kwake.
Ngati kuli kofunikira kusankha mthunzi umene chitsanzocho chikugwirizana, ndiye kuti kufunika kwa kupirira kumakhala ku 0, komwe kudzalangiza pulogalamuyo kuti asawonjezerepo mndandanda uliwonse.
Pamene phindu la "Kupirira" 0, timapeza mzere wochepa wosankhidwa womwe uli ndi mthunzi umodzi wokha womwe umagwirizana ndi chitsanzo chomwe chinachokera ku fano.
Kutanthauza "Kuleza Mtima" zingathe kukhazikitsidwa kuyambira pa 0 mpaka 255. Pamwamba phindu ili, malo akuluakulu adzasankhidwa. Nambala 255 yomwe ikuwonetsedwa mmunda imapangitsa chidacho kusankha chithunzi chonse (tone).
Ma pixel apakati
Mukamakambirana zofunikira "Kuleza Mtima" Wina akhoza kuzindikira chinthu china. Pogwiritsa ntchito gradient, pulogalamuyi inasankha pixels kokha m'deralo zolembedwa ndi gradient.
Malo amtunduwu pansi pa mzerewo sanaphatikizidwe muchisankho, ngakhale mithunzi yomwe ili pambaliyi ndi yofanana kwambiri ndi gawo lapamwamba.
Chinthu chinanso chokhazikika ndi choyenera ichi. "Wokongola" ndipo iye akutchedwa "Ma pixel adakali". Ngati mame akuyang'anizana ndi parameter (mwachisawawa), pulogalamuyi idzasankha ma pixel omwewo omwe akufotokozedwa "Kuleza Mtima" monga yoyenera kuwala ndi mthunzi, koma mkati mwa malo omwe anagawa.
Ma pixeloni ena ali ofanana, ngakhale atchulidwa kuti ndi abwino, koma kunja kwa malo omwe adawagawa, sangalowe m'dera lolemedwa.
Kwa ife, izi ndi zomwe zinachitika. Ma pixel onse ofanana pansi pa chithunzicho adanyalanyazidwa.
Tidzayesa wina kuyesa ndikuchotsa bokosi loyang'anizana "Ma Pixels Ogwirizana".
Tsopano dinani mbali imodzi (kumtunda) ya gawoli. "Wachiphamaso".
Monga tikuonera, ngati "Ma pixel adakali" mapikseli onse pa chithunzi chomwe chikugwirizana ndi zoyenera amaletsedwa "Kuleza Mtima", zidzatchulidwa ngakhale zitakhala zosiyana ndi zitsanzo (zilipo mbali ina ya fano).
Zosintha zamakono
Miyendo iwiri yapitayo - "Kuleza Mtima" ndi "Ma pixel adakali" - ndizofunikira kwambiri pakugwiritsa ntchito chida "Wokongola". Komabe, pali zina, ngakhale zili zofunikira kwambiri, komanso zofunikira.
Posankha ma pixelesi, chidachi chikuchita izi, pogwiritsa ntchito tizigawo ting'onoting'ono, zomwe zimakhudza khalidwe la kusankha. Zingawoneke m'mphepete mwazitali, zomwe zimatchedwa "makwerero."
Ngati chiwembu chokhala ndi geometric (shape) chikufotokozedwa, ndiye kuti vutoli silingayambe, koma posankha magawo a "makwerero" osapangidwira, ndizosapeŵeka.
Mphepete mwachitsulo chosasunthika chingathandize "Kutonthoza". Ngati mdima wotsatizana waikidwa, ndiye Photoshop angagwiritse ntchito khungu kochepa pamasankhidwe, ndipo palibe zotsatirapo pamtunda wotsiriza.
Malo otsatirawa akutchedwa "Chitsanzo kuchokera ku zigawo zonse".
Mwachinsinsi, Magic Wand imatengera chitsanzo cha hue kuti chisankhe kokha kuchokera ku chingwe chomwe panopa chimasankhidwa pa piritsi, ndiko kuti, yogwira ntchito.
Ngati mutayang'ana bokosi pafupi ndi chikonzero ichi, pulogalamuyo idzatengera chitsanzo kuchokera pazomwe zili m'kalembedwe ndikuiika pamasankhidwe, motsogozedwa ndi "Kupirira.
Yesetsani
Tiyeni tione momwe tingagwiritsire ntchito chida. "Wokongola".
Tili ndi chithunzi choyambirira:
Tsopano ife tidzatenga m'malo mwa mlengalenga ndi athu, okhala ndi mitambo.
Ndiroleni ndikufotokozereni chifukwa chake ndinatenga chithunzichi. Chifukwa ndizofunikira kukonza ndi Magic Wand. Mlengalenga ndi pafupifupi mpangidwe wangwiro, ndipo ife, mothandizidwa ndi "Kuleza Mtima", tingathe kusankha.
M'kupita kwa nthawi (adaphunziramo) mumvetsetsa kuti mafano omwe angagwiritsidwe ntchito angagwiritsidwe ntchito.
Timapitiriza kuchita.
Pangani kapangidwe ka wosanjikiza ndi njira yothetsera CTRL + J.
Kenaka tengani "Wokongola" ndi kukhazikitsa motere: "Kuleza Mtima" - 32, "Kutonthoza" ndi "Ma pixel adakali" kuphatikizapo, "Chitsanzo kuchokera ku zigawo zonse" olumala.
Ndiye, pokhala ndi wosanjikizana ndi kopani, dinani pamwamba pa thambo. Timasankha zotsatirazi:
Monga mukuonera, thambo silimaperekedwa kwathunthu. Chochita?
"Wokongola"monga chida chilichonse chosankha, chiri ndi ntchito imodzi yobisika. Ikhoza kutchedwa monga "onetsani kumalo osankhidwa". Ntchitoyi imatsegulidwa pamene fungulo likugwera pansi ONANI.
Kotero, ife timamveka ONANI ndipo dinani mbali yotsala yosadziwika ya thambo.
Chotsani chinsinsi chosafunikira DEL ndipo chotsani kusankha ndi chingwe chodule. CTRL + D.
Zimangokhala kuti zipeze fano la mlengalenga chatsopano ndi kuziika pakati pa zigawo ziwiri mu phukusi.
Pa chida ichi chophunzirira "Wokongola" akhoza kuonedwa ngati wangwiro.
Fufuzani chithunzicho musanagwiritse ntchito chida, gwiritsani ntchito makonzedwe mwanzeru, ndipo simungalowe m'gulu la ogwiritsa ntchito omwe amati "Wowopsya wand." Iwo ndi osowa mtendere ndipo samvetsa kuti zipangizo zonse za Photoshop ndizophatikizapo. Mukungodziwa nthawi yoyenera kugwiritsa ntchito.
Luso lanu mu ntchito yanu ndi Photoshop!
