Ua bokeh nyhuv

Kuv xav nrog koj tham txog yuav ua li cas ua lub bokeh nyhuv nyob rau hauv cov kev yees duab. Nyob rau hauv no tsab xov xwm kuv mam li qhia koj yuav ua li cas rau tsim ib tug plooj nyob rau hauv lub keeb kwm yav dhau, raws li nws yuav tau mus thov cov duab. Yog li ntawd, qhib lub pib duab nyob rau hauv Photoshop. Tam sim no koj muaj ob tug duplicate tom qab txheej. Thaum zoo li no yog ua li cas, lub visibility ntawm lub thib ob backup disconnect txheej. Peb npaj mus rau lub txheej nrog rau cov thawj daim ntawv.

Yuav kom ua lub bokeh cov nyhuv hauv Photoshop, koj yuav tsum mus qhib tus ceev daim npog qhov ncauj hom thiab xaiv ib tug radial gradient. Xim rau nws yog tsim nyog los muab cov dub thiab dawb, thiab nyob rau hauv lub qhov rais ntawm dithering thiab transparency tsis xyuas. Tom qab tag nrho cov chaw tawm los ntawm no ceev daim npog qhov ncauj.

Peb mus txuas ntxiv rau perceive bokeh nyhuv. Thov cov ntxaij lim dej plooj. Ua li no, nyem rau ntawm qhov Lim tab, thiab muaj xaiv cov plooj kev xaiv thiab los yeej muaj teev cov tsis rau nws nyob rau ib lub qhov tob ntiav ntawm peb daim teb. Tom qab hais tias, tshem tawm cov active xaiv thiab thov ib tug Gaussian plooj lim. Radius teem rau ob pixels rau nws. Ces tsiv mus nyob rau lub thib ob txheej duplicate. Muaj xws li cov visibility ntawm no txheej, ces nws yog tsim nyog los thov ib lub lim thiaj li hu ua ntse teb. Nws yuav tsum qhia kom meej rau nram qab no tsis: nyhuv - 100%, ces tus voos kheej-kheej ntawm - 0.5% thiab lub kaum sab xis - 0. Muab daim tshev thawv nyob rau hauv lub ca. Xaiv cov kev xaiv kom tshem tawm Gaussian plooj.

Ntxiv mus, peb lub hom phiaj yog rau duab lub department nyob rau hauv lub foreground los ntawm cov keeb kwm yav dhau los mus ua kom cov bokeh nyhuv. Qhov no yog ua los ntawm extracting lim. Khiav nws thiab nias Alt rau Kontral thiab X-txiv neej. Peb muab tus txhuam loj ntawm lub kaum ob thiab muab tso rau ib tug zuam nyob rau hauv lub thawv nrog ib tug kev ntxhib los mos parameter 5. Ces xim nws lub keeb kwm yav dhau, thiab ces siv lub sau cov yam xim sau lub ntsiab duab. Tom qab hais tias, txo cov opacity ntawm peb txheej rau 42%.

Tam sim no peb yuav tsum tau mus theej tawm tam sim no txheej, li ntawd, lov tes taw rau visibility ntawm yav tas los ib. Tshem tawm cov daim npog qhov ncauj txheej thiab rov ntxiv nws. Softening ntawm cov npoo ntawm cov duab uas siv ib tug mos txhuam nrog tsim tsawg transparency. Tom qab no, txav bokeh ntxim rau ib tug ua hauj lwm daim ntawv.

Theej tawm txheej uas muaj ib tug kev ntxhib los mos bokeh. Rau lub hom phiaj no cov thawj txheej ntawm no kev ntxhib los mos yog tsim nyog los ntxiv ib daim npog qhov ncauj txheej uas thov ib tug radial gradient. Nws xim yuav tsum xim dub thiab dawb. Tam sim no hloov lub overlay hom ntawm cov thawj txheej muaj ib tug kev ntxhib los mos bokeh, lub soffit. Opacity teem rau ntawm 58%.

Ntxiv nws yog tsim nyog los hloov cov hom ntawm overlay ntawm lub thib ob txheej ntawm tib ntxhib los mos rau bokeh lightening hom. Thaum no opacity yog yuav tsum tau 25%. Ib zaug ntxiv theej tawm txheej muaj bokeh kev ntxhib los mos, ces nrhiav tus duplicate qis khaubncaws sab nraud povtseg nyob rau hauv uas lub cais ntsiab duab. Tam sim no hloov lub hom overlap nrog lightening. Nws opacity yuav tsum ncav cuag 45%.

Tom qab tag nrho cov ntaub ntawv khaubncaws sab nraud povtseg hauj lwm ua ke nrog rau ib leeg. Mus rau duab ntawv qhia zaub mov, xaiv tus kho lus, ces cov tom qab kob thiab teem nws cov saturation +8. Tom qab ntawd thov distortion lim. Yog hais tias koj tau ua txhua yam kom raug, lub bokeh nyhuv koj yuav kom meej meej pom. Yog hais tias ib yam dab tsi yog tsis ncaj ncees lawm, rov qab kuv pom zoo kom zoo zoo.
