Kakade ke, umhleli engundoqo ugwayimbo amandla kukujolisa ekuphuculweni kabukhali kweefoto, kodwa yokugcina kweso, eqinileyo kakhulu, kwaye kufuneka kodwa ukufumanisa ukuba izixhobo kakhulu - nokuba ukulahleka, okanye ukucacisa. Kodwa nayiphi na imeko, kweso yenye isihluzo lusetyenziswa kunye nenani mali othile ukhukuliseka ukuvuka phantse ukusuka kuguqulelo kwinguqulelo. Hi xikombiso, ku Photoshop CS5 kwaba-10 kweso okucoca, kunye CS6 kubo 14.

Zonke izixhobo amandla zinto zimbi inkqubo "Photoshop" buzinze sub-menu "Blur" kwi "Ukuhluza" menu (Blur). Iinjongo kunye nezizathu usaba uluhlu kuya kufuneka ukuba elide, kodwa kwiimeko ezininzi eyona njongo iphambili yale kunyango ukwahlula isifundo osemqoka defocusing isithuba imvelaphi kunye nokwenza umthamo umfanekiso xa iyonke.

Amacebo okucoca "Blur" yaye "Blur"

Indlela elula yentsimi - isixhobo "kweso" kwi "Photoshop". Yena akanayo iinketho, ngoko akuyomfuneko ukuba ufake useto. Blur "dibanisa", oko kuthetha ukuba ukhukuliseka ngakumbi, yaye ke ukuba akunjalo ngokwaneleyo, intlanganisela iqhosha Ctrl + F liya kusungula kwakhona.

Gaussian Blur

Oku mhlawumbi sixhobo kakhulu ethandwa (ukusuka kuthetha ibulale) usebenzisa algorithm ukuthandabuzwa ukuba igophe Gaussian. Apha Isityibilikisi "Radius", unako ukufumana isidanga efanelekileyo kweso. Too, kanye njengakwimeko yangaphambili, kodwa isebenza ngakumbi.

iimvakatjhi isakhelo

Esi sisihluzo kwakhona lumiselwe kuphela algorithm injini radius kodwa osebenza ngayo yahlukile lokucoca ulwelo elandulelayo. Apha, iimvakatjhi kwenzeka ngokuthi avareji ngemibala pixels ezingabamelwane, kwaye injini nje avareji utshintsho kulo mmandla.

"Okrelekrele" kweso

Uninzi iimvakatjhi smart "Photoshop" yaye ubizwa ngokuba "Smart ...", yaye eli cebo lokucoca esenza ntoni igama layo liyichaza, nangona Russian "Photoshop" igama elithi "smart" kuchaphulo, kodwa inguqulelo IsiNgesi ayikho (Smart Blur).

iimvakatjhi ziqu

Kuxhomekeka kwindlela ekhethiweyo kweso lokucoca ukuba zilinganisa umfanekiso usaba kubangelwa camera ujikelezo xa embindini umfanekiso kuhlala ezibukhali kodwa awucaci kwimiphetho (indlela isanqa), okanye ukuze ufumane isiphumo apho kwenzeka nge gumbi yokungqubana elibukhali (Linear / Zoom). Le Amandla kweso hlengiswe umtyibilikisi "inani", kodwa usenako ungakhetha isiphumo iziko (nengalo) kunye nomgangatho nomfanekiso imveliso.

Mbumbulu image kweso xa adubula izinto eguquguqukayo

Kunye lokucoca "Motion Blur" "Photoshop" lenza ifoto isiphumo uphawu usaba, efunyanwa xa zokudubula sifundo limaxhaphetshu. Ngoko ke, ngaphandle ngobunzulu isiphumo, injini bume "ukulinganisa / ukulinganisa" nkongomiso lowu ngokwendalo (engile).

iimvakatjhi indawo

Ngaphandle kwento yokuba igama lecebo lokucoca ulwelo Surface Blur kuthetha ukuba "kweso kumphezulu" kwezinye iinguqulelo ze "Photoshop" ngenxa yesizathu esithile ngokuba "olubulala bomhlaba."

Esi sisihluzo iyasebenziseka blurs umfanekiso lo gama kugcinwe ezona imikhosi yazo, kunye nezicwangciso zakho imigca kunye nemida, ngoko ke idla ngokusetyenziswa ukujongana iinkozo nengxolo digital, lokuhanahanisa i parameters, "Radius" yaye "Threshold".

iimvakatjhi Mysterious singu

Kukho umntu onjalo kweso kwi "Photoshop" (avareji /-avareji), umsebenzi apho uyibize ngokuthi olubulala kuba le lokucoca ugcwalisa nje ngokupheleleyo umfanekiso lonke okanye indawo ekhethiweyo umbala umndilili umfanekiso okanye movie.

Ukuba kufakwe elicebo lokucoca ulwelo kumfanekiso yonke kwi phinda, uze ukunciphisa ukungabonisi ikopi kunokuba tonally lungelelanisa umfanekiso, kodwa ngeenjongo loo nto sisigqibo sobulumko. Kodwa ukuba kweso-avareji ezinye Isiqwenga nokunciphisa semenu ukwenza mbhalo afike umdla.

lens iimvakatjhi

Ngoko nezwi ngokuthi IsiNgesi Igama Lens Blur filter, leyo luguqulelo Russian yenkqubo "Photoshop" kuthiwa "kweso aphansi ubunzulu yasendle." Le kweso ngo "Photoshop" lisetyenziswa kwiimeko apho ndikho ogqibeleleyo kumfanekiso yonke ayikho wanelisekile yi eyakhiwa okanye ezinye izizathu, oko kukuthi, xa ugxininiso kufuneka ahlale kwindawo ethile okanye into kuphela. Nathi kufuneka kuphela ukubonisa icebo lokucoca ukuba mfanekiso kufuneka ibe kufutshane, kwaye ngakumbi, ukudala ebizwa ngokuba yi-imephu nobunzulu, njengoko elinokuba, umzekelo, eyakhiwa alpha umsele yomgama okanye ithambeka iphiramidi ebonisa ukusuka omnyama mhlophe.

Unekhono algorithm yesihluzi se yokubala kweso, uya kuqonda ngoko nangoko ukuba iinkalo abamnyama - zezo zezona zikufuphi lwecamera. Emva kwabo ibanga balandele zonke izithunzi ya hina. Kaloku, iindawo ezimhlophe kususwa kangangoko kunokwenzeka kwi-camera, uze apha kufuneka enze iimvakatjhi ebanzi imvelaphi. Onke amanye amacebo ziya kwenza kwi okusemandleni, ukuthobela parameters izicwangciso ukuba umnike.

Alpha (engenanto) udale imiphantsi Ebiziweyopalette iqhosha ehambelana bavula glazik kwi RGB umgca ukubona kunye nomfanekiso ngokwayo, yizalise abamnyama ukuba ithambeka emhlophe, wachitha ukusuka kwindawo esikufutshane kumgca ndiniphuthume, kufuneka ne ukubukela engile oyifunayo.

Emva kokuba uvale ukubonakala umjelo alpha, buyela kwijelo RGB kwaye ziquka Lens Blur lokucoca ulwelo. Ngaphezu koko, kwi "Umthombo" ukukhetha channel yethu alpha kwaye ukunqakraza imouse kummandla nowomfanekiso kumele ukuba ekugxilwe (okanye umgama Ukubuza ukuya injini focal ngongoma "Focal kumgama kweso"). Kulungile Isityibilikisi "Radius" khetha isiphumo Blur (ngesidanga defocus). Ezinye izicwangciso imiphumela ezifihlakeleyo kakhulu asetyenziswa ayifane zemifanekiso eziqhelekileyo, ngoko nqakraza KULUNGILE, uze uphawule ngokwaneliseka ngayo kweso kwi "Photoshop" olusengqiqweni. Kunokuba ukulinganisa ububanzi befildi.

Hand iphume "Izixhobo Photoshop." Indlela yokusebenzisa nangomnwe ukunyhibhela imifanekiso

Kunye izihluzi (plugins) ukuya kweso ukuba wonke "umsebenzi omdaka" wenziwa kuthi, kwi "Photoshop" ngenjongo efanayo inika izixhobo ngenxa yomsebenzi manual ezinokwenziwa phantse bonke abakwaziyo lokucoca nkqu kancinci kancinci, mhlawumbi kungcono (nangoku ezenziwe).

Xa uyilo, le ngebrashi, nto leyo yezicwangciso umsebenzi lwenziwa ngokucofa i "emandla". Kuxhomekeke kwisayizi kunye kwanokuqi- brush ekhethiweyo zinto zimbi Isixhobo ukuba kweso yonke imifanekiso okanye iinkcukacha kwindawo ethile. Ukutshintsha iikona ezibukhali zinakho agudileyo, isixhobo ngobuqili kuthambisa imisele ukuba bamba phantsi i ekhohlo iqhosha le mouse, ngoko ke kuya kusebenza ibhrashi kwenye imo డొమైన్ idomeyini, uqinisa isiphumo. Esi sisixhobo ezandleni elungileyo ukwenza phantse yonke into, ubuncinane nge umsebenzi onjalo, ukuba kweso indlela imvelaphi, Blur Tool ukusingatha lula.

Isixhobo "Finger", okwabizwa ngokuba iSmudge Isixhobo (smear, iSmudge), ngokwenene waneka umzobo, ukuba uthe waba ngomnwe kumfanekiso esandula vali. ukusebenza Force kwakhona ukutshintsha "emandla", kodwa ngokungafani isixhobo asebumelwaneni kusekho umsebenzi "Ukuzoba umnwe", apho (a uphawu kwibhokisi), siya ukusasaza umbala wokuqala. isicelo Practical of "umnwe" ufumana, umzekelo, iinkcukacha podrisovki entle nakulwabiwo bezinto ezinzima ezifana iinwele, uboya, oboya njalo, kwakunye uhlobo mbumbulu womzobo.

imiphetho fifi

Nge arsenal enamandla lwezixhobo, ubuchule, yaye iindlela kweso ukuba uyakwazi ukucima i ifoto eqhelekileyo ibe ngelaphu elihle yobugcisa, kweso ekupheleni ukuba "Photoshop" elula. Ukuze wenze oku, khetha i indawo musani ukuba ngokuxhomekeke isiphumo, kwaye kwimida ye kweso ngokukhetha enye isihluzo ngasentla. Kodwa kaninzi zisetyenziselwa le njongo "Gaussian Blur."

Ukuba ukhetho usebenzisa izixhobo ezisemgangathweni, ukufumana imida ezigudileyo ezibekelwe yona yokukhuhla (kwi toolbar phezulu okanye kwi menu "Khetha> Guqula"). Kwaye ukuba (Q) zisetyenziselwa le njongo "imaski Quick" utshintsho-gingxi kulawulwa lokukhanya brush.

Kuzo zonke iimeko kufuneka Ungabuyisela ukhetho (Shift + Ctrl + I), hayi kweso umfanekiso ngokwawo, hayi buthelezi. Hi ndlela leyi, u akunyanzelekanga ukuba usebenzise ukhetho ukuba kweso ekupheleni kunokuba ngesandla usebenzisa i "Blur" (Blur Isixhobo).

amacebo okucoca amatsha

Xa uguqulelo Photoshop CS6 wafika "webutho," okucoca kweso. Xa submenu "Blur" ababeqala kuhlala phantsi yedwa phezulu, ngo kocingo etsolo ukusuka ifitsha filter endala.
