Fotokozani (rapidnaya) kujambula pa pafupipafupi kuposa muyezo (24 f / s) ntchito kulenga zotsatira za kuyenda pang'onopang'ono, zomwe zikufunika ku ziyerekezo mafilimu, TV, masewera a sayansi mafilimu a kanema. Izo ntchito cholinga yolanda masewera osiyanasiyana chifukwa kusewera zinthu zoyenda Kamangidwe kapena zochitika zachilengedwe monga nthawi yoikika lonse. Pa zenera ndi chochita kungoganiza slowdown kuwombera zochitika, ndipo mu nkhani iyi wowerenga wapatsidwa mwayi woganizira njira wogwirizira gawo ndi mbali bwino distinguishable.

Features kudya kuwombera

Mitundu ya kuwombera:

• inapita, kapena Rapid-kuwombera (32-200 K / a) ikuchitika ndi zida muyezo ndi ndowa limagwirira likukulira kayendedwe ka filimu;
• mkulu-liwiro kuwombera 200-10 ndi pafupipafupi 000 kupita / kuchokera anaonetsetsa mosalekeza yunifolomu zoyenda filimu ndi njira kuwala ndi zipangizo mpheto kuyatsa. Inapita mphukira ndi ya m'manja kwa galimoto zimayenda ochiritsira zida zosiyanasiyana kapenanso kusangalala ndi yaitali pafupipafupi osiyanasiyana wofunikila bata fano.

kinosomok Technology kukhala pafupifupi zikutsatiridwa kuyambira chaka cha 1955, kupatulapo ndi chilengedwe cha shutter amagetsi, koma fano tsopano atathana osati pa filimu ndi pa ndondomeko ya mawerengetsedwe digito, motero kuonetsetsa mtengo chimango cha 100 miliyoni pa mphindi.

Digiri ya mathamangitsidwe okha kuti kamera ndi matabwa ake ndi mphamvu. Pakuti zida ankachita masewera amakhala ndi inapita patsogolo kuwombera - 64-72 f / m, kwa akatswiri - kuti 360-600 / s. makamera amakono amatha pafupipafupi 200 / s ndi kuwonjezeka ake pang'onopang'ono kuti alandire wapadera zotsatira munamupha mlingo. Ngati mukufuna mathamangitsidwe, ndiye anadza kwa mpheto mafelemu pa filimu.

chimango Voterani

Pali mitundu yosiyanasiyana ya kuwombera mu sayansi ndi ntchito Cinematography, makamaka kwa maphunziro a zochitika zakanthawi ndi njira. Mmodzi wa iwo ndi mkulu liwiro, kapena Rapid-kuwombera, pa pafupipafupi mafelemu oposa 250 pa mphindi, amene amalola Chithunzi njira kufikako maganizo a diso la munthu chifukwa cha lalifupi nthawi liwiro mkulu kapena zochitika.

chiwerengero cha maofesi kafukufuku zikuphatikizapo:

• zoyenda wa zamoyo: mlingo chimango ndi 100 mpaka 300 K / s, Tingafinye - 1/1000;

• kumaliseche magetsi (miliyoni 10-100 f / s) ndi zina zotero.

luso zidule

Ndi zosiyanasiyana zinthu, osiyanasiyana hardware ndi pafupipafupi mosiyanasiyana, nkotheka akatswiri videography maofesi a mkulu khalidwe. Mkulu luso zipangizo kuwonjezera muyezo limagwirira fano processing komanso ntchito boosters kuwala, fasteners mwamsanga-kumasulidwa, makompyuta ndi kuwala transducers.

A zithunzi mkulu-liwiro ikuchitika zambiri ndi pulsed magwero kuwala (nyali kumaliseche, kuunika kochokera kabotolo, mphanvu mipata ndi mpweya imeneyi).

Chronophotography - wapakatikati pakati pa njira chithunzi-imprinting ndi kujambula zochitika magawo zotsatizana ntchito onsewo kudula shutter. Zithunzi zomwe ndi laminated pa wina ndi mzake ndi amaphatikizidwa mu tepi imodzi. njira amagwiritsa kuyenda mosalekeza wa chinthu. Zotsatira wapadera lili mandala momasuka ndi kuwala kung'anima.

Njira mkulu-liwiro kujambula

1. Okhala pa filimu intermittently kusuntha ikuchitika pa pafupipafupi 600 / s ntchito makina dongosolo filimu zoyendera.
2. More cranking pa pafupipafupi 1000 / s akuyendera ntchito zipangizo pneumatic kapena filimu sayenda chifukwa kumadalira zotanuka amene anawapanga mitsinje filimu.
3. kusunthira zipangizo photosensitive ntchito kukwaniritsa mafurikwense apamwamba.

Chikusokosera zotsatira za masinthidwe motsatizana zotheka ndi kusamutsidwa filimu wachibale chinthu m'njira zotsatirazi.

kusinthitsa pakompyuta

njira imene kudula ndi odulidwa obturators kwa nthawi yochepa kukhudzana. Pakuti nthawi yayifupi a munthawi kuchepetsa wachibale fano kuwala alibe olumpha chovomerezeka blur negativity. Pamafunika zimachitika likukulira chiwalitsiro bursts (10-7 Kutalika kwa wachiwiri) kapena kumtunda kwa ogwira cholumikizira vavu obturator ngati, koma m'malo kukhala ting'onoting'ono kudula mphako (mmodzi kapena angapo).

kusinthitsa kuwala

Ngati cranking akadali chithunzi kumaphatikizapo ndi yunifolomu kayendedwe ka film, m'pofunika n'chongoletsa osiyanasiyana kukhudzana kuchepetsa wachibale fano svetovospriimchivogo zinthu kupita kuwala chimawala dongosolo kuwala zikugwira ntchito pa liwiro ndi m'njira kuyenda filimu.

Kukhazikitsa malipilo kuwala galasi polyhedron suti, mbale galasi kapena prism mothamanga. Kukula ndi malo a amafotokozera kuwala awonetsetse kuti liniya kusamutsidwa kayendedwe ka mafelemu a. Film Mzere adzaikidwe padziko polyhedron mu wapadera njira kanema. Njira ntchito njira otsika mphamvu.

Malire pa mafurikwense apamwamba elektrokommutatsii kuthekera zochepa kuchepetsa imeneyi pakati kung'anima, ndipo pamene kuwala - liwiro kasinthasintha wa valavu chimbale ndi awiri ake.

liwiro ziyerekezo

Kwa nsalu yotchinga zithunzi kuonera zoyenda pang'onopang'ono ntchito, monga kuli kotheka ndi pafupipafupi kujambula kuchuluka, ndipo pa deceleration kayendedwe ka filimu purojekitala lapansi. The sangathe ndi kuti discontinuity akuoneka, ndi zina njira mkulu-liwiro zambiri kusiya asakuoneka, zobisika pakati akatemera anajambula pa kuwombera. Ngati deceleration ndi oposa 1 f / m, kusonyeza chithunzi akufanana ndi Wopanda bwanji. Motero, slowdown optional kunadetsa m'malo kudya kuwombera.

njira zamakono za kujambula

1. makamera zamakono zili ndi dongosolo pakompyuta wosasunthika, koma Mkhalidwe overcranking analengedwa ndi thandizo la kutalika chosinthika, "monopod" kupereka chithunzi bata popanda kugwedezeka.
2. zinthu ofukula ndi lateral mbali chimango ayenera kukhala yomweyi.
3. njira zimenezi wa kanema kanema, ngati kusinthana kwa pafupi ndi ang'ono ndi sing'anga, amaonedwa kalembedwe wabwino. Sverhupotreblenie scalability akufooka kum'patsa choncho ndi bwino nthawi zina kusiya kujambula, kujambula kumasulira moyenera, kenako kupitiriza.
4. Kutalika akadakwanitsira kwa maganizo a chiwembu akuti ndi pafupifupi 5 masekondi, pazipita - 12 kusunga liveliness ndi mphamvu ya kanema ya.
5. White Kusamala kolowera m'chipinda chongopeka anayatsa tikulimbikitsidwa kuti zichitidwe pamanja.
6. Kunja mzere - osati mbali yomaliza chimene chimasiyanitsa kanema katswiri: ziyenera kutero pa msinkhu wa pakati pa mzere viewfinder kapena pamwamba pake pang'ono. Zithunzi zimene gawo chapamwamba danga chimango wakumwamba wotanganidwa ndi 2/3, kwa voteji anazindikira.
7. Kupanga mafelemu voliyumu ya sing'anga ndi lalikulu kukula kutsogolo kwa mandala akhoza adzaikidwa nkhani iliyonse, mochenjera kulenga chithunzi cha kuya ndi lonse la fano.
8. Pamene inu kusankha kamera ngodya kuwombera muyenera kuganizira malingaliro osiyana, popitirira olakwika Mwachitsanzo, kusonyeza chinthu omvera ndi "Oweruza", komanso mwa maso a kunja amatsata. Ndipo sitepe iliyonse kwa woyendetsa - ndi chida chatsopano patsogolo luso lake ndi anapeza latsopano zikutipatsa mlingo wake.

Tiyenera amatchulanso timatsatira pantchito: Pa zochitika zazikulu si ambiri mumtengomo mfundo zomwe ali oyenera kuwombera bwino, kotero muyenera kusamalira zinthu zonse zofunika pasadakhale.
