2. Lub qhov: Qhov loj ntawm qhov qhib hauv lub koob yees duab lens, feem ntau ntsuas hauv f-stops. Lub aperture loj dua (qis f-stop tus nqi) tsim DoF ntiav, thaum lub aperture me me (siab dua f-stop tus nqi) ua rau DoF ntxaum.
3. Sab nrauv: Qhov kev ncua deb ntawm lub koob yees duab thiab cov ntsiab lus. Raws li qhov kev kawm tau los ze zog rau lub koob yees duab, DoF ua ntiav.

Los ntawm kev kho cov xwm txheej no, koj tuaj yeem tswj qhov tob ntawm qhov chaw hauv koj cov animations nres, tsim kom pom ntau dua cinematic thiab xav.

Cov tswv yim tswv yim rau kev tswj qhov tob ntawm qhov chaw nyob rau hauv nres

Tam sim no peb tau hais txog cov hauv paus, cia peb nkag mus rau qee cov lus qhia ua tau zoo rau kev ua tiav qhov xav tau DoF hauv koj cov phiaj xwm nres:

Pib los ntawm kev teeb tsa koj lub koob yees duab mus rau hom kev tuav. Qhov no tso cai rau koj kom muaj kev tswj kom tiav ntawm qhov aperture, shutter ceev, thiab ISO chaw.

Yog tias koj tab tom tsom rau qhov ntiav DoF, siv lub aperture loj dua (qis f-stop tus nqi) thiab ntev focal ntev. Qhov no yuav pab cais koj qhov kev kawm thiab tsim kom muaj kev nkag siab tob tob.

Hloov pauv, yog tias koj xav tau DoF ntxaum, siv qhov me me aperture (siab dua f-stop tus nqi) thiab luv dua focal ntev.

Qhov no yuav ua kom ntau dua ntawm koj qhov xwm txheej hauv kev ua kom pom tseeb, uas tuaj yeem muaj txiaj ntsig zoo rau kev ua haujlwm nres-tsim animations nrog ntau txheej txheej.

Kev sim nrog qhov sib txawv ntawm koj lub koob yees duab thiab raug saib seb nws cuam tshuam li cas rau DoF.

Nco ntsoov tias thaum qhov kev kawm tau los ze zog rau lub koob yees duab, DoF yuav ntiav.

Kev xyaum ua rau zoo meej!

Qhov ntau koj sim nrog ntau lub koob yees duab teeb tsa thiab kev ncua deb, qhov zoo dua koj yuav ua tiav qhov xav tau DoF hauv koj cov animations nres.

Dab tsi nam piv yog qhov zoo tshaj plaws rau kev tso tseg cov animation?

Tus nam piv rau nres cov animation tuaj yeem sib txawv nyob ntawm seb qhov project tshwj xeeb thiab nws qhov kev siv. 

Txawm li cas los xij, ib qho piv txwv zoo sib xws rau kev tso tawm cov yeeb yaj kiab yog 16: 9, uas yog tus qauv nam piv rau cov yeeb yaj kiab siab.

Qhov no txhais tau tias 1920 × 1080 rau HD animation lossis 3840 × 2160 rau 4K animation tab sis tseem nyob ntawm qhov piv ntawm 16: 9.

Kev siv 16: 9 nam piv tuaj yeem muab cov hom dav dav uas tsim nyog rau kev nthuav tawm ntawm niaj hnub widescreen TVs thiab saib.

Nws tseem tuaj yeem pab tsim cov yeeb yaj kiab zoo rau koj cov animation.

Txawm li cas los xij, nyob ntawm seb koj xav siv koj cov animation, lwm qhov piv txwv yuav zoo dua. 

Piv txwv li, yog tias koj cov animation yog npaj rau kev tshaj xov xwm, tej zaum koj yuav xav siv ib qho square nam piv (1: 1) los yog ib tug ntsug piv (9:16) kom zoo dua haum rau cov hom ntawm kev sib raug zoo platforms.

Thaum kawg, qhov piv txwv uas koj xaiv yuav nyob ntawm qhov kev xav tau tshwj xeeb thiab cov hom phiaj ntawm koj qhov project. 

Xav txog yam xws li kev npaj siv, lub platform uas cov animation yuav tshwm sim, thiab qhov pom kev zoo uas koj xav ua kom tiav thaum xaiv qhov piv rau koj cov yeeb yaj kiab nres.

concluding xav

Txhawm rau nres cov yeeb yaj kiab animation, lub koob yees duab zoo tshaj plaws yog nyob ntawm qhov xav tau thiab cov xwm txheej tshwj xeeb raug ua yeeb yaj kiab. 

Piv txwv li, qhov dav aperture tuaj yeem tsim qhov tob tob ntawm qhov chaw, uas yog qhov tseem ceeb rau kev cais cov ntsiab lus, thaum lub aperture nqaim tuaj yeem tsim qhov tob ntawm qhov tob, uas yog qhov tseem ceeb rau kev ntes cov ntsiab lus sib txawv hauv qhov xwm txheej. 

Ib yam li ntawd, lub kaw lus qeeb qeeb tuaj yeem tsim cov lus tsa suab plooj, uas tuaj yeem siv los xa cov kev txav mus los, thaum lub kaw lus ceev ceev tuaj yeem khov cov lus tsa suab thiab tsim cov animation du.

Thaum kawg, los ntawm kev paub lub koob yees duab teeb tsa thiab sim nrog cov txheej txheem sib txawv, cov animators tuaj yeem tsim qhov pom kev zoo nkauj nres cov animations uas zoo tshaj tawm cov lus xav tau thiab kev xav.
