Ukudubula Rapid - Rapid. Film noma ividiyo ngokudubula nge imvamisa ngesekhondi 32 200. videography professional

Veza (rapidnaya) ukuqopha at a imvamisa ephakeme ukwedlula okujwayelekile (24 f / s) isetshenziswa ukudala umphumela ngokunensa, okuyinto ezifunwayo projection amabhayisikobho, ithelevishini, isiqophi imidlalo, cinema ngokwesayensi. Isetshenziselwa injongo ekuthumbeni imicimbi yezemidlalo, ngoba udlala izakhi ukunyakaza isakhiwo noma zemvelo ngokuvumelana isethi isikhathi embulungeni. Esikrinini kuboniswa i iplanethi Ukwehla shot imihlola, futhi kulesi simo umbukeli unikezwa ithuba lokucabanga zesikhashana isigaba izinqubo kanye izingxenye kabi akachazeki.

Izici sokudubula okusheshayo

Izinhlobo sokudubula:

• yashesha, noma Rapid-ngokudubula (32-200 k / a) Kwenziwa ama-apharathasi ejwayelekile futhi ebhakedeni indlela ukunyakaza ngakanye wefilimu;
• sokudubula ngesivinini 200-10 nge imvamisa 000 kuya / kusuka waqinisekisa okuqhubekayo iyunifomu ezinyakazayo ifilimu nge izindlela zokukhwabanisa optical kanye electronic zilula. ihlumela, olubhekene nezifundiswa ezingasebenzi kuthiwa ephathwayo kusuka imoto ehambayo nge professional noma amateur apharathasi ezivamile nge enwetshiwe imvamisa uhla edingekayo ukuze isithombe ukuzinza.

kinosomok Technology ahlale cishe ingashintshiwe kusukela ngonyaka ka-1955, ngaphandle ukudalwa i yesivalo ngogesi, kodwa isithombe manje aselungisiwe hhayi ifilimu futhi ukulandelana matrices digital, ngaleyo ndlela ekuqinisekiseni izinga lozimele ezingu-100 ngomzuzwana.

Degree of ukushesha kukhawulwe ikhamera by isimo sawo futhi Dynamics. Ukuze imishini amateur libhekene sokudubula yashesha - 64-72 f / s, for the professional - ukuba 360-600 / s. amakhamera Modern ukwazi ukunikeza imvamisa 200 / s ukwanda yayo kancane kancane ukuze uthole ekhethekile ukusebenza wabulala izinga. Uma ufuna ukusheshisa, bese yakhetha manipulation ozimele on ifilimu.

Uhlaka Ukukala

Kunezinhlobo ezihlukahlukene sokudubula esenzeke namabhayisikobho yezesayensi nasezinzuzweni osetshenziswayo, ikakhulukazi ngoba izifundo imihlola okusheshe izinqubo. Omunye wabo ngesivinini, noma Rapid-shot, ngesikhathi imvamisa abangaphezu kuka-250 ngesekhondi, okuvumela ukuba ifotho izinqubo bezibona ezingafinyeleleki esweni womuntu ngenxa iDemo isikhathi high speed noma izenzakalo ngamunye.

Isibalo izindawo zocwaningo kungafaka:

• motion izidalwa: izinga lozimele ivela 100 300 K / s, extract - 1/1000;
• ukusebenza izindlela (1-10000 k / s);
• ukubhujiswa ukuqhuma (ayizinkulungwane 10-100 k / s);
• igesi shock wave (100,000 - 1 million / s);
• osenyameni kagesi (izigidi ezingu-10-100 f / s) kanye nokunye okufana nalokho.

namaqhinga Technical

Nge ezihlukahlukene izimo, anhlobonhlobo hardware kanye nokuvama ezihlukile, kungenzeka videography professional high izindawo. High imishini ubuchwepheshe ngaphezu ejwayelekile processing image indlela futhi iqashe booster optical, okusheshayo-ukukhululwa iziqobosho, transducers ngogesi futhi optical.

A bethwebula ngesivinini Kwenziwa ngokuvamile ngokukhanya imithombo pulsed (izibani ocucuzayo, imithombo ukukhanya ukuqhumisa, inhlansi izikhala nge air isikhawu).

Chronophotography - Lesisemkhatsini phakathi indlela isithombe-imprinting kanye ukuqopha imihlola izigaba ezilandelanayo usebenzisa ujikelezisa umqhewu yokucina. Izithombe okuholela kuthiwa laminated ku nomunye futhi zenziwe itheyiphu olulodwa. Indlela esebenzisa ngokunyakaza okuqhubekayo into. imiphumela abahlukile kunikeza lens evulekile nge ukukhanya flash.

Izindlela ze-high-speed ukuqopha

1. Sihleli ifilimu ngezikhathi ezihambayo Kwenziwa at a imvamisa of 600 / s usebenzisa mechanical uhlelo ifilimu ezokuthutha.
2. cranking angeziwe at a imvamisa 1000 / s eziqhutshwa yilo Mnyango usebenzisa amadivaysi womoya noma ifilimu ukuhamba ngenxa kokuhlanganisayo nokunwebeka ukuthi akhiwa kweziteshi ifilimu.
3. ezihambayo izinto photosensitive zisetshenziselwa sifinyelele amaza ephakeme.

Fiphaza umphumela kugucuka ngokulandelana kungenzeka ne displacement we isihlobo ifilimu ukuba into ngezindlela ezilandelayo.

usuke electronic

Indlela lapho umqhewu kuyinto obturators cut izikhathi elilinganiselwe ukuchayeka. Okwesikhathi esifitshane isikhathi ifreyimu benani isithombe optical ayeqi kuvunyelwe ukufiphala engemihle. Kudinga okukhanyisa ngakanye ishayela Ukuvutha (10-7 nesikhathi yesibili) noma umfula kwabasebenzi isixhumi valve obturator like, kodwa kungase esikhundleni kube ezincane umqhewu notch (elilodwa noma ambalwa).

usuke optical

Uma cranking namanje image kuhilela ukuhamba kuqhathaniswa umfaniswano ifilimu, kubalulekile iwukudambisa uhla ukuchayeka benani isithombe svetovospriimchivogo impahla yokuhamba ekukhanyeni lembhali uhlelo optical ezisebenza ngesivinini futhi ohlangothini wefilimu ukunyakaza.

Ukuqalisa isinxephezelo optical esibukweni polyhedron isudi, ipuleti ingilazi noma nezibhebhe kunyakaza. I nendzawo timphawu optical kumele baqinisekise ukuthi komugqa ukufuduka ukuhamba ozimele. Icwecwe lefilimu kufanele libekwe kobuso polyhedron e isiteshi movie ekhethekile. Indlela isetshenziselwa ongaphakeme-umthamo izinqubo.

Umkhawulo at amaza ephakeme elektrokommutatsii kungenzeka elilinganiselwe ukunciphisa isikhawu phakathi kwawo, ukhanya, futhi lapho optical - ijubane ukujikeleza disc valve futhi ubukhulu bayo.

okwehlisa kwelivi

Ukuze uthole screen ezibukwayo ukubukwa moshini isetshenziswa, njengoba kungenzeka nge imvamisa anda ukuqopha, futhi ngesikhathi deceleration ukunyakaza ifilimu kule wokudlala. Ububi ukuthi discontinuity sobala, futhi ezinye izinqubo ngesivinini ngokuvamile baphume emehlweni, kufihlwe phakathi isibhamu wathwebula ngesikhathi kwenzeka lesi sigameko sokudubula. Uma deceleration ingaphezu 1 f / s, isithombe ukuboniswa sifana nge-slide show. Ngakho-ke, i-Ukwehla ozikhethela ngokuya esikhundleni sokudubula okusheshayo.

Izinqubo zanamuhla yokuthwebula ibhayisikobho

1. amakhamera zanamuhla anemisila yokuthenga izinhlabamkhosi zikagesi eliletha ukuthula, kodwa overcranking qualitative wadala ngokusekelwa ubude adjustable, "monopod" ukunikeza isithombe ukuzinza ngaphandle shaking.
2. izinto Kuqondile futhi Uhlaka lateral izinhlangothi kufanele kube ngokulinganisa.
3. zindlela video amavidyo, njengenhlangano alternation eduze ne amancane naphakathi, ezibhekwa isitayela ezinhle. Sverhupotreblenie scalability amandla. umbukeli, ngakho-ke kungcono ngezinye izikhathi ukuze umise ukuqopha, ukuqopha ukuhumusha ngokwezinga okudingeka senze ngalo, bese uqhubeke.
4. Isikhathi elikhulu bezibona ngesakhiwo ubhekwa imizuzwana mayelana 5, esiphezulu - 12 ukuze alondoloze ukuphila futhi dynamism we amavidyo.
5. Ibhalansi emhlophe kulungiselelwa ekamelweni eyayenziwe ovuthayo Kunconywa ukuba kwenziwe ngesandla.
6. Umugqa umkhathizwe - isici zokugcina esihlukanisa ividiyo professional hhayi: okufanele kwenzeke ezingeni phakathi kusitholi sokubonwayo umugqa noma kancane ngenhla. Scenes lapho ingxenye engenhla Uhlaka isikhala wasezulwini elalihlala 2/3, ukuze voltage waqonda.
7. Ukuze wenze amapulanka ivolumu medium and enkulu usayizi phambi lens zingafakwa yisiphi isihloko, kungabonakali ukudala isithombe ukujula isikali yesithombe.
8. Uma ukhetha ikhamera engela sokudubula kufanele ucabangele ngezindlela ezahlukene, becabangela okungale kwalokho eyeqisayo, isibonelo, bonisa intfo ngetetsamelilwati "abahluleli", kanye ngeso kumuntu wangaphandle. Futhi isinyathelo ngasinye ukuze opharetha - isenzakalo esiyingqopha-mlando entsha e ubuciko bayo kanye ukutholakala omusha kuphakamisa ezingeni layo.

Kufanele futhi ingasaphathwa lokuziphatha: Ngesikhathi semicimbi emikhulu akuzona eziningi kangaka amaphuzu uyibuka, afaneleka yokudubula yimpumelelo, ngakho kufanele sinakekele zonke izimo ezidingekayo kusengaphambili.
