Yuav ua li cas kom muaj txiaj ntsig zoo Yam Ntxim Saib Ntxim Ua Kev Siv Lub Teeb Nruab Nruab 3 Suab Nruab Nruab Nruab Nruab

Ib qho ntawm Jodi cov lus tsis ntev los no nyob rau hauv MCP Facebook phab yog ib qho kev sib tw rau cov kev pab txog saib teeb meem teeb pom kev zoo li cas. Hauv Jodi tus ncej, pom cov xov ntawm no, nws tau nyob ntawm qhov kev tawm dag zog rau nws tus ntxhais, thiab nws tau txwv los ntawm nws qhov siab tshaj plaws ntawm lub lens ntawm f / 2.8, thiab xav tau tua ntawm 1 / 300-1 / 500 txhawm rau kom khov.

Tau muaj nyob rau hauv cov xwm txheej zoo sib xws, Kuv paub ntawm kuv tus kheej tias nws tau tawm tsam. Raws li kab tshoob kws yees duab Kuv tuaj yeem qhia koj li cas ntxias tau nws tuaj yeem muab tua hauv tsev teev ntuj tsis zoo lossis lub tsev txais tos!

Tau txais cov kev raug raug rwj qis los ntawm kev sib dhos, kaw nrawm, thiab ISO, thiab lawv txhua tus ua haujlwm ua ke. Hloov ib tus nqi los ntawm ib qho nres, thiab koj yuav tsum them rov qab los ntawm kev kho ib qho ntawm 2 qhov tseem ceeb ntawm ib qho ib zaug.

Hauv Jodi cov ntaub ntawv, nws tau kom nws qhov teeb tsa hluav taws xob ceev tau teeb tsa mus rau 1/300 thiab 1/500 nyob ntawm qhov kev nqis tes ua, thiab qhov aperture ntawm f / 2.8, thiab nws xav tau 1 lub teeb ntxiv. Kuv cov lus ntawm ncej yog “Thawv koj ISO rau 12,800 lossis 25,600 thiab siv Lightroom Lossis Photoshop lub suab nrov txo hauv kev xa, thiab lees txais lub lis ua "nqi" ntawm kev txhaj tshuaj."

Kuv paub qee qhov ntawm koj tsuas yog tsaus muag ntawm kev xav tua ntawm qhov siab ntawm ISO, dab tsi nrog txhua lub suab nrov ntawd ... tab sis kuv yuav qhia koj li cas 5 daim duab nyob hauv chav teeb 3 thaum siv kom raug, yuav pab txo cov suab nrov hauv koj yees duab. Muaj kev lag luam tawm, thiab kuv yuav piav qhia cov ntawd thiab. Kuv Kuv txhob txwm zam kev sib tham seb qhov twg zoo lossis tsis zoo hauv kev yees duab; nws yog lub ncauj lus dav dav, uas rau kuv rhais rau kev nyiam ua yeeb yam ntawm tus kws yees duab (thiab cov neeg siv khoom) ib feem. Yooj yim heev, Kuv yuav sau rau qhov hauv paus uas koj muaj lub suab nrov ISO hauv kev yees duab uas koj xav tau kom txo, thiab tsis paub pib qhov twg.

Suab nrov los qhov twg los?
Thaum koj tua nyob rau hauv qis teeb, koj lub koob yees duab lub sensor tau sib zog ua haujlwm kom pom "qhov chaw" koj tau tua. Thaum koj kho qhov ISO hauv lub koob yees duab digital, koj tau kho lub koob yees duab lub siab rau qhov pom kev los ntawm kev nce los yog txo qis dua ntawm kev ua kom nrov zog uas lub koob yees duab tso tawm tau ua nrog lub teeb uas tau ntes thaum lub kaw tau qhib. Qhov ntau koj yuav tsum ua kom nrov loj ntawm "teeb ​​liab", ntau suab nrov koj qhia sim ua ib yam dab tsi los ntawm tsis muaj dab tsi. Cov daus uas koj pom nyob hauv TV thaum koj xaiv ib qho channel uas tsis tau tshaj tawm yog qhov tshwm sim ntawm kev ua kom nrov ntawm cov xov tooj tsis muaj zog lossis ploj.

Nqa 1: Qhov me me ntawm lub teeb uas tau txais zog = suab nrov.
Takeaway 2: Yog tias koj tua ntawm ISO siab, nrog ntau lub teeb, koj yuav tsis pom ntau lub suab nrov. Sim nws!
Nqa 3: Peb tsis txhob ua kom tiav cov qoob loo, tsuas yog suab nrov. Grain yog ua los ntawm kev ua tau zoo ntawm ISO, zoo tib yam hauv zaj duab xis.

Muaj hmoo rau peb, cov neeg txias ntawm Adobe tau muab peb lub suab nrov txo rau hauv Lightroom 3 (nws yog tib lub cav xws li hauv lub koob yees duab tshiab tshiab Nyoos rau Photoshop CS5, yog li koj tuaj yeem siv tib txoj kev rau Lub Koob Yees Duab Raw).

Cia peb mus saib nws. Tua cov yees duab ntawm qhov siab tshaj ISO teeb tsa koj lub koob yees duab tso cai (koj yuav tsum tau pab kom ISO nthuav dav hauv cov ntawv qhia ... sab laj rau phau ntawv lossis koj nyiam tshawb nrhiav tshuab).

Qhib daim duab hauv Lightroom 3.

Nyob rau hauv lub Lub Teeb Qub 3 Tsim Kho Qauv, koj yuav pom cov Nthuav dav seem…

nthuav cov Nthuav dav ntu (nyem rau ntawm lub xub ntiag) los qhia peb cov phooj ywg tshiab, lub suab nrov txo me me nyob rau hauv Hliav hlauv seem.

Nov yog tus txheej txheem cej luam los ntawm cov sliders 'zog raws li tau piav qhia los ntawm Adobe:

Luminance: Txo cov suab nrov nrov
nthuav dav: Luminance ua suab pib sib cuam tshuam
Tshaj tawm: Luminance sib piv

xim: Txo cov xim suab nrov
nthuav dav: Xim suab xim ua haujlwm

Yog li cia peb pom lawv hauv "kev nqis tes ua". (Saib qhov kuv nyuam qhuav ua dhau los muaj? Clever, yog?)

Nco ntsoov tias, thaum kuv hais txog kev tua, kuv tsuas yog ua haujlwm nrog 5 lub vias hauv qhov tsis muaj suab nrov hauv Ntu 3. Ua rau saib cov yees duab kuv yuav ua haujlwm nrog: (Kuv tsis tau ua ib qho xim kho rau daim duab, qhov no ncaj nraim tawm ntawm lub koob yees duab):

Hubba, hubba! (50 hli, f / 11, 1/60 sec) (aws, tu siab heev tej poj niam, tab sis kuv coj…)

Kuv tus kheej tua cov duab no rau ntawm Canon 5D Mark II, ntawm 25,600 ISO. Kuv tau siv daim duab no vim nws muaj:

1) suab lus tawv nqaij
2) Tsaus Ntuj
3) Nruab nrab suab nrov
4) Cov ntsiab lus tseem ceeb
5) Kuv (peb tuaj yeem mus yuam kev li cas?)

Saib ntawm lub suab nrov tau pom zoo tshaj plaws ntawm cov txee dub dua kuv sab laug lub xub pwg. Oy gevalt:

A 1: 1 zoom qhia qee qhov ugliness uas peb yuav tshem tawm (tsis yog kuv, lub suab nrov):

Hauv daim duab saum toj no, koj tuaj yeem pom cov spackling ntawm liab, ntsuab, thiab xiav pixels. Txoj cai ntawd muaj high-ISO ua suab nrov. Nws yog ib qho tseem ceeb kom nco ntsoov tias lub ntsiab yog vim li cas nws zoo li tsis zoo vim tias Kuv yuav lossis tsis muaj kev dag (Kuv tau ua), los ntawm kev hloov lub xim slider tus nqi rau 0 yog li koj tuaj yeem pom lub suab zoo duaCov. Lub teeb taws 3 qhov chaw rau tus swb no yog 25, uas yog qhov pib zoo rau tsis pom xim suab nrov.

Xovxwm Z txhawm rau tog Zoom mus txog 1: 1 ntawm daim duab, & xaiv xaiv qhov chaw koj tuaj yeem pom kev sib xyaw zoo ntawm cov teeb thiab tsaus:

xim
Pib los ntawm maj mam tsiv lub xim swb mus txog thaum tag nrho cov xim nrov tau ploj mus, lossis ntawm theem uas tsim nyog. Hauv kuv daim duab, nws zoo li lub xim slider ua haujlwm ntawm txog 20Cov. Thaum koj txiav txim siab nyob qhov twg xim slider ua haujlwm zoo tshaj plaws rau koj duab, txav mus rau tus Nthuav dav yob pem.

Nthuav dav
cov Nthuav dav swb (hauv qab no lub xim zawv zawg) yog siv los saib yog tias peb tuaj yeem nqa rov qab txhua kab xim nthuav dav. Qhov no yog kev sim tag nrho thiab yuam kev, & yog tias koj nias qhov no Nthuav dav zawv zawg dhau lawm, koj yuav tau tig suab nrov rau hauv daim foos ntawm daim duab cuav rov qab rau hauv lub yees duab. Tus kheej, Kuv tsis mus dhau los 50 ntawm no, tab sis sim ua cov kab swb rau koj daim duab: pib ntawm 0, txav nws maj mam, thiab pom tias nws ua qhov txawv txav. Yog tias koj tsis tuaj yeem pom ib qho kev hloov pauv, tso nws ntawm 0.

luminance
Thaum koj zoo siab nrog rau kev txo qis ntawm lub suab nrov, dhia mus rau tus luminance npov kab, thiab pib hloov cov no mus rau sab xis. Nco ntsoov, qeeb yog tus yuam sij. Qhov no yog qhov koj lub qhov muag los hauv rov ua si dua. Koj yuav tsum txiav txim siab qhov zoo tshaj plaws tshuav ntawm poob ntawm suab nrov / grain thiab poob ntawm cov ntsiab lus hauv koj daim duab. Thaum koj tau txais mus rau qhov nruab nrab zoo siab, koj tuaj yeem txav mus rau qhov pom kev Nthuav dav yob pem. Rau kuv cov duab, Kuv zoo siab nrog Luminance slider teeb rau 33Cov. Kuv tau thawb nws kom txog thaum kuv nyuam qhuav pib ploj nthuav dav ntawm kuv cov tawv nqaij, thiab tom qab ntawd thim nws nqis los ntawm qhov kev ceeb toom.

Lo lus ceev faj (ntawm no yog qhov kev lag luam tawm uas kuv tau qhia koj txog ua ntej): yog tias koj thawb lub luminance yob dhau deb, tib neeg thiab tsiaj yuav tawm los zoo nkauj ntxiv tom qab ntawd qee yam yuav tsum yog-tsis muaj npe, yas, perky, tus ntxhais cov khoom ua si zoo nkauj uas yog tus tswv ntawm Corvette, ib lub dav hlau, thiab lub camper (uas yeej tsis haum nrog ntiag tug dav hlau). Kuv tsis yog hais tias ', tab sis kuv tsuas yog hais'.

“Kuv nyiam lub ntsej muag yas…” - Luminance ploj mus lawm!

Nthuav dav
Tom ntej no, pib zawv zawg the Nthuav dav slider sab laug thiab sab xis (lub neej ntawd yog 50, uas feem ntau yog qhov zoo), txhawm rau saib seb koj tuaj yeem tau rov qab ntau dua (ntug) cov ncauj lus tsis tas rov ua suab nrov. Ib zaug ntxiv, tsis muaj tus qauv; nws yog koj li duab, koj lub zeem muag kos duab, koj tus nqi slider. Kuv tabtom tawm hauv kuv li ntawm 50.

piv
Thaum kawg, xaub lub suab nrov nrov tsis nyob rau sab xis los saib seb koj puas tuaj yeem rov qab me ntsis kom meej me ntsis. Raws li nws lub npe cuam tshuam, qhov no yob muab nthuav dav rov qab rau hauv koj daim duab raws li kev ua kom pom lub teeb ci. Nws tuaj yeem ua haujlwm zoo tiag tiag los qhia cov ntsiab lus uas tau muag muag hauv cov kauj ruam saum toj no, thiab hauv kuv daim duab, Kuv tsis ntshai kom muab cov ntawv swb rau 100 coj rov qab qee cov ntawv nyeem rau kuv lub ntsej muag.

Voila! Kuv tam sim no muaj ib qho duab zoo siv:

"Puas yog kub nyob ntawm no, lossis nws puas yog kuv?"

Tam sim no uas kuv zoo siab dua nrog daim duab, cia kuv ceev nrooj recap kuv nrov nrov txo workflow:

Qhib duab, thiab ua pa (tsis tshua…)
Hloov mus rau tsim module.
Qhib Nthuav dav seem.
kho xim yob saib seb yog lwm yam uas tsis yog lub neej ntawd 25 muab kuv cov qhabnias zoo dua
kho Nthuav dav daim swb (hauv qab xim) txhawm rau saib yog tias kuv tuaj yeem nqa rov qab txhua kab nthuav dav raws xim
kho luminance zawv zawg kom txog thaum lub noob ua tau los yog kom txog thaum lub duab pib ua kom ncaj, tom qab ntawv rov tawm ib qho tad
kho Nthuav dav lub npov (hauv qab Luminance) txhawm rau saib yog tias kuv tuaj yeem nqa rov qab txhua tus ntug nthuav dav raws li luminance
kho piv swb rau sim thiab nqa rov qab qee cov kab ntawv kawg ntawm kev nthuav dav

Yuav kom ncaj ncaj, Kuv tsis tshua, yog tias puas yog, siv qis 2 hauv qab (xim thiab Qhia Tau). Chav rau lub teeb 3 yog qhov tseem ceeb yog qhov ze heev uas kuv yuav xaiv.

Nco ntsoov, tsis muaj lub koob yees duab tsis muaj khawv koob, TSIS MUAJ, thiab TSIS TSIS (qhov zoo, muaj qhov ua tsis haum) luminance swb kab-yas-saib). Tsuas muaj dab tsi uas haum rau koj cov neeg siv.

Raws li kev pab txog kev yees duab, peb pom peb cov duab txawv dua li peb cov neeg tau txais los ntawm qhov kev xav pom. Yog tias koj ntes ib qho kev xav, lossis lub sijhawm, thiab koj tiag tiag ntsia nws, Kuv xav twv kuv cov nyiaj qiv yuav tsev uas koj tus neeg yuav tsis pom lub suab nrov.

Yog tias lawv ua, koj tam sim no paub txo nws!
