Cov tsom iav telephotomuaj qhov ntev ntawm qhov muag pom thiab qhov pom nqaim, uas ua rau lawv coj cov khoom nyob deb los ze dua, ua kom qhov muag pom me dua, ua rau keeb kwm yav dhau tsis meej, thiab ntes tau ntau yam ntsiab lus hauv cov xwm txheej nyob deb. Lawv siv dav hauv kev thaij duab duab, toj roob hauv pes, tsiaj qus, thiab kev ua kis las.
Txawm li cas los xij, cov tsom iav telephoto kuj muaj qhov tsis zoo, uas yuav tsum tau muaj qee yam kev txawj siv thaum thaij duab.
Cov tsom iav telephoto hnyav thiab muaj qhov tob ntawm thaj chaw me me, ua rau lawv yooj yim raug lub koob yees duab co thaum thaij duab. Yog li ntawd, nws yog ib qho tseem ceeb kom paub txog cov txheej txheem kom raug thaum siv lawv:
1.Siv lub tripod lossis stabilizer los ua kom daim duab ruaj khov
Cov tsom iav telephoto muaj qhov ntev focal ntev thiab yooj yim rau lub koob yees duab co, uas tuaj yeem ua rau cov duab tsis meej. Kev siv tripod lossis stabilizer tuaj yeem txhim kho qhov ruaj khov thiab qhov ntse ntawm cov duab. Yog tias ua tau, kev siv lub lens lossis lub koob yees duab uas muaj peev xwm ua kom cov duab ruaj khov kuj tseem tuaj yeem txo qhov kev co ntawm lub koob yees duab.
Thaum thaij cov duab uas muaj zog (xws li kev ua kis las lossis kev thaij duab ntawm txoj kev), cov tripods yuav tsis muaj qhov yooj ywm tsim nyog. Hauv cov xwm txheej zoo li no, siv tau monopod hloov chaw, txo qhov mob caj npab yam tsis cuam tshuam kev txav mus los sai thiab kev teeb tsa. Yog tias tsis muaj tripod, koj tuaj yeem siv cov khoom hauv ib puag ncig, xws li muab lub lens tso rau ntawm cov ntaiv, pob zeb, lossis nraub qaum rooj zaum, los muab kev txhawb nqa ruaj khov.
2.Tuav lub cuab yeej kom zoo thaum tuav lub cuab yeej
Thaum siv lub lens telephoto, kev siv lub koob yees duab kom zoo yog qhov tseem ceeb heev. Xyuas kom koj sawv ruaj khov, tuav koj txhais tes ze rau koj lub cev, tuav lub koob yees duab kom nruj nrog ob txhais tes, tuav lub koob yees duab kom ze rau koj lub ntsej muag, ua pa kom txaus, thiab maj mam nias lub khawm shutter (tsis txhob nias hnyav).

Kev ruaj khov yog qhov tseem ceeb thaum thaij duab nrog cov iav telephoto
3.Teeb tsa ISO thiab shutter speed kom zoo
Yuav tsum tau kho qhov chaw teeb tsa ISO raws li lub teeb ib puag ncig kom ntseeg tau tias daim duab ci thiab meej. Hauv qhov xwm txheej uas muaj teeb tsawg, kev nce ISO kom raug yuav ua rau lub shutter speed ceev txaus thiab lub duab ci zoo, tiv thaiv kev tsis meej pem los ntawm lub shutter speed qeeb. Piv txwv li, thaum thaij duab tsiaj qus lossis kev ua si nawv, feem ntau siv lub shutter speed ntawm 1/500 vib nas this lossis sai dua los thaij cov sijhawm nrawm.
4.Xaiv qhov aperture thiab qhov tob ntawm daim teb kom haum
Siv lub qhov (aperture) loj (xws li F2.8 lossis F4) yuav ua rau pom qhov tob tob, ua rau keeb kwm yav dhau tsis meej thiab ua rau pom qhov tseem ceeb. Qhov no zoo heev rau kev thaij duab neeg thiab tsiaj qus, tab sis kev tsom kom meej yog qhov tseem ceeb heev.
Siv lub qhov (aperture) nruab nrab (xws li F5.6 lossis F8) muab qhov sib npaug ntawm qhov tob txaus ntawm daim teb thiab qhov tsis meej ntawm keeb kwm yav dhau, zam kev teeb meem kev tsom mus rau lossis qhov tob tsis tob dhau uas tuaj yeem tshwm sim los ntawm kev siv lub qhov loj heev.
Thaum xav tau qhov tob ntawm daim teb ntau dua, lub qhov me dua (xws li F8 lossis F11) tuaj yeem siv los xyuas kom meej qhov ntse ntawm pem hauv ntej mus rau tom qab.
Siv lub lens telephoto thiab teeb tsa cov kev teeb tsa ntawm lub koob yees duab kom raug kuj tseem ceeb heev.
5.To taub thiab siv qhov "kev xav ntawm qhov chaw sib zog" kom zoo
Cov tsom iav telephotomuaj peev xwm "nias" cov khoom ntawm qhov deb sib txawv hauv tus ncej, ua rau lawv zoo li ze dua thiab me dua li qhov lawv muaj tiag. Qhov no ua kom yooj yim rau kev teeb tsa thiab txhim kho qhov tob thiab qhov cuam tshuam zoo nkauj hauv daim duab. Qhov no muaj txiaj ntsig zoo heev rau kev thaij duab toj roob hauv pes thiab kev thaij duab txoj kev.
Piv txwv li, hauv kev thaij duab toj roob hauv pes, lub lens telephoto tuaj yeem ua rau cov roob deb thiab cov ntoo pem hauv ntej zoo li sib tshooj, tsim cov duab txheej; hauv kev thaij duab txoj kev, lub lens telephoto tuaj yeem tsim kev sib txuas zoo dua ntawm cov tsev keeb kwm yav dhau thiab cov ntsiab lus, tiv thaiv keeb kwm yav dhau los kom tsis txhob pom tseeb thiab hloov chaw ua rau nws yog ib feem tseem ceeb ntawm zaj dab neeg ntawm daim duab.
6.Ua tib zoo saib xyuas cov teeb pom kev zoo thiab huab cua
Cov hmoov av, cov dej noo, thiab lub teeb ultraviolet hauv huab cua tuaj yeem txo qhov sib piv thiab cov xim ntawm cov khoom nyob deb. Cov iav telephoto tshwj xeeb tshaj yog rhiab heev rau qhov no, ua rau cov duab zoo li tsis meej. Thaum thaij duab hauv qhov chaw muaj teeb pom kev zoo lossis lub teeb ci ntsa iab, lub hau lens lossis lub lim polarizing tuaj yeem siv los txo qhov ci ntsa iab thiab txhim kho qhov tseeb thiab xim ntawm cov duab.
Thaum siv lub lens telephoto, xyuam xim rau lub teeb pom kev zoo thiab huab cua
7.Ua tib zoo mloog kom meej meej
Cov tsom iav telephotomuaj qhov tob ntawm thaj chaw me me, ua rau lawv yooj yim hloov qhov tsom, yog li qhov kev tsom kom raug yog qhov tseem ceeb. Nws raug pom zoo kom siv lub koob yees duab lub luag haujlwm tsom ib qho lossis lub pob rov qab, thiab tsom rau qhov tseem ceeb ntawm tus neeg, xws li lub qhov muag ntawm tus neeg lossis qhov tseem ceeb ntawm ib yam khoom tsis txav.
Thaum thaij cov khoom uas txav mus los (noog, cov neeg ncaws pob), tswj qhov kev tsom mus rau qhov twg. Ua ntej thaij duab, koj tuaj yeem teeb tsa qhov deb ntawm qhov kev tsom mus rau qhov ntawd los txo lub sijhawm nrhiav kev tsom mus rau qhov ntawd thiab txhim kho qhov ceev ntawm kev tsom mus rau qhov ntawd. Thaum thaij cov duab uas tsis txav, koj tuaj yeem hloov mus rau qhov kev tsom mus rau qhov ntawd, tsom mus rau qhov ntawd ua ntej ua ntej kaw qhov kev tsom mus rau qhov ntawd.
8.Xaiv qhov ntev ntawm lub teeb thiab qhov chaw teeb tsa raws li cov xwm txheej sib txawv
Cov tsom iav telephoto tsis yog ib qho kev daws teeb meem uas haum rau txhua tus. Thaum thaij duab, koj yuav tsum xaiv qhov ntev ntawm lub lens thiab cov yam ntxwv raws li cov ntsiab lus thiab cov xwm txheej sib txawv kom tau cov duab zoo.
Piv txwv li, thaum thaij duab neeg, koj tuaj yeem xaiv qhov ntev ntawm 85mm-135mm, qhov aperture ntawm F1.8-F2.8, qhov chaw teeb tsa ISO ntawm 100-400, qhov ceev ntawm shutter ntawm ≥1/200 vib nas this, thaij ntawm qhov deb ntawm 3-5 meters ntawm tus neeg, thiab tsom mus rau qhov muag; thaum thaij kev ua si nawv, koj tuaj yeem xaiv qhov ntev ntawm 200-400mm, qhov aperture ntawm F2.8-F4, qhov chaw teeb tsa ISO ntawm 800-3200, qhov ceev ntawm shutter ntawm ≥1/1000 vib nas this, thiab siv kev thaij duab tas mus li los taug qab cov neeg txav mus los.
Cov tsom iav telephoto xav tau qhov chaw teeb tsa sib txawv nyob ntawm qhov chaw
9.Ua tib zoo saib xyuas cov txheej txheem sib xyaw ua ke
Thaum siv cov tsom iav telephoto, nws yog ib qho tseem ceeb uas yuav tsum tau ua tib zoo saib xyuas cov txheej txheem kev teeb tsa, xws li siv cov ntsiab lus pem hauv ntej, kev sib npaug, thiab cov kab ua ntej. Thaum thaij duab nrog lub tsom iav telephoto, ntxiv cov ntsiab lus pem hauv ntej rau ntawm tus neeg, xws li paj lossis pob zeb, tuaj yeem ua rau muaj qhov tob thiab txheej txheej hauv daim duab.
Yog tias tus neeg ntawd muaj qhov sib npaug, ces siv cov qauv sib npaug los ua kom daim duab zoo nkauj dua. Cov kab uas ua rau pom tseeb xws li txoj kev, cov ntaiv, lossis cov dej ntws kuj siv tau los coj tus neeg saib los ntawm sab xub ntiag mus rau sab nraud.
Tsis tas li ntawd, thaum thaij duab nrog ib daim duablub lens telephoto, nws raug pom zoo kom txuag cov duab hauv hom ntawv RAW, uas tso cai rau kev ua tiav tom qab tsim nyog, xws li kho qhov pom kev, ua kom ntse, thiab txo qhov nrov.
