Kunze TTL Flash ("zvese uye sync ...")

 

Kunze, mukati mezuva, urikushandisa mwenje sechiedza chekuzadza uye kwete mwenje mukuru kana anokosha sezvamunoita mudzimba.

 

Kujekesa kwako kunofanirwa kugara kuchitsamira pakubwinya kwechiedza chako chikuru (mune ino zuva zuva), saka uchafanirwa kutanga wamisikidza kuratidzwa kwayo. Zvakare, iwe unofanirwa kuziva nezve yako kamera "sync" kumhanya. Kune mazhinji Canon makamera iri 1/200 kana 1/250. YeNikon inogona kuenda zvakakwira se1 / 500.  Kana iwe usingazive kuti kamera yako yekumhanyisa mhanyisa chii, unofanirwa kutarisa kumusoro X-kubvumirana mubhuku remuridzi wekamera yako, kana pamhepo.

 

Iyo sync yekumhanyisa ingori inokurumidza kumhanya shutter kumhanya iwe yaunogona kushandisa neyakajairika flash pulse.  Pane imwe Flash mode iyo inokutendera iwe kuti uende pamusoro pekuenderana kunotsanangurwa pazasi.

 

Sezvo kumhanya kwevhavha chiri chinhu chinokanganisa kuburitswa, iwe unofanirwa kunge uchifunga muShutter Speed ​​yekumusoro mode (kunyangwe iwe uchizopfura nekamera yako muManual exposure mode). Kuchengeta shutter kumhanya pa, kana pazasi sync muchiedza chakajeka, shandisa yakaderera ISO kumisikidza kamera yako ine - kazhinji 100 kana 200. Izvi zvinokupa iwe kuratidzwa pamwe nekuvhurwa kukuru uko kunogoneka. Kana zvichidikanwa iwe unogona kudzikisa shutter kumhanya, izvo zvinoda apuro diki, kuti uwane kuwedzera kwakadzika kwemunda.  Asi mune yakajairika flash mode, usambo pfuura pamusoro pe "sync" yekamera.

 

Nhanho dzako kusvika zvino ndedzekuti:

 

1. Sarudza yakaderera ISO mamiriro

2.Seta shutter kumhanya kune iyo kamera's sync kumhanya (1/200 kusvika 1/500 zvinoenderana nekamera inogadzira uye modhi)

3. Gadzirisa kuzarura kwechiedza (shandisa zvakajairika mu-kamera metering)

4. Kana paine kudzama kweMunda kunodiwa, dzikisa shutter kumhanya uye gadzirisazve ap

 

Ipapo iwe unongobatidza mwenje kuti uwedzere kuzadza. Mune TTL modhi iwe unogadzirisa iyo inoburitsa Flash kuti inwe nekushandisa iyo flash's EV kudzora - pamwezve zvimwe uye kubvisa zvishoma. Paunenge uine mwenje wakawanda munzvimbo, inguva yakanaka kushandisa Nikon's TTL-BL kumisikidza (BL inomiririra Balanced Lighting). Inoedza kusanganisa kuzadza nechiedza chiripo, uye nekudaro, inoderedza iyo inoburitsa flash  NaCanon kamera iwe unongoda kudzikisa iyo EV.

 

Paunenge uchinge uine izvo pasi, iwe unogona ikozvino kudzora izvo zviviri pachena zvakasiyana. Iyo yakavakirwa-mukati mita inokupa iwe kumashure kuratidzwa uye iyo yekumira mamiriro inokupa iwe kumberi kuratidzwa. Nekudaro, edza kusviba kumashure nekusajekesa zvishoma, uye kugadzirisa kumberi kumberi (iyo yekuvhenekera kuratidzwa kana FEC) kumusoro uye pasi futi.

 

Nekudzidzira, iwe unenge uine kutonga kwakazara kwekuwanda kwekuzadza iwe kwaunoda pamwe nekureruka kana kusviba kwaunoda kumashure

 

Muchiedza chekunze chekunze, iwe unongovhenekera mwenje worega iwo mwenje muTTL modhi ikubate iko kuratidza kwako.  Iyo zvakare inova kiyi mwenje, uye iwe unoshandisa inononoka shutter kutora imwe ambient mwenje zvakafanana nezvamakadzidza kushandisa iyo flash mukati.

 

Muchiedza chakajeka kana iwe kwazvo unoda kudzika kwakadzika kweMunda uye urikushandisa flash ye "kuzadza", uchafanirwa kushandisa High Speed ​​sync mode.  Nikon naOlympus vanozvidaidza kuti Focal Plane (FP) sync modhi, nekuti inobvumidza kushandiswa kwe "focal ndege" shutter inowanikwa mune Imwe Lens Reflex (SLR) mhando kamera.  Kana iwe uine yazvino digitaalinen kamera, seCanon XSi kana XTi, kana Nikon D90, inowanzozonzi DSLR yeDigital Imwe Lens Reflex.

 

MuHS kana FP sync modhi iyo Flash inoburitsa akateedzana nekukurumidza kwakanyanya mwenje wechiedza kutevedzera masikati.  Inoita izvi nekudya bhatiri rako simba.  Zvakare, zvinongobatsira chete kana zvichishandiswa padhuze-mukati nekuti hapana kupenya kumwe kupenya kwechiedza kunogadzirwa.  FP sync modhi yaive imwe yeOlympus yakagadzirwa yakawanikwa pane yavo OM-2 kamera uye flash system.

 

Iwe pamwe wave kushamisika kuti chii chingaitika kana iwe ukamisa kamera yako pamusoro peiyo sync kumhanya mune yakajairwa flash "kupomba" maitiro.  Zvakanaka, hazvizokuvadza kamera.  Asi, iwe uchaona kumucheto kwakasviba mune yepamukati studio kupfura, uye muchiedza chakajeka kunze uchishandisa flash sekuzadza, mwenje wekuzadza haufukidze iyo furemu.  Nehunyanzvi, pane chero shutter inomhanyisa pamusoro yekubvumirana maketeni maviri anovhura nekuvhara kuti mwenje usvike kune sensor, haatombo vhura zvachose.  Keteni rechipiri rinoteedzera rekutanga parinopfuura neparinonzwa.

 

Kune nzira dzakawanda dzekushandisa furashi kugadzira mwenje unonakidza. Zvekare, izvi zvinongova zvakareruka nekukurumidza kutanga dzidziso yezvimwe zvinhu zvaunofanira kufunga nezvazvo kana uchipfura kunze uine Flash.
