Taura (rapidnaya) filming pane imwe kakawanda kupfuura mwero (24 f / s) chinoshandiswa kusika nokuitika zvishoma inofamba, riri kudiwa ari fungidziro mafirimu, terevhizheni, mitambo yemavhidhiyo, zvesayenzi cinema. Rinoshandiswa nechinangwa rokutora dzemitambo, nokuti kuridza inofamba marongerwo zvinhu kana zvakasikwa maererano nguva akamboona. On chidzitiro anoratidzwa yokufungidzira slowdown pena mananara, uye ichi kana Fafitera anopiwa mukana funga zvokungoitawo kutotanga pezvakaitwa uye havaratidzi distinguishable nhengo.

Features zvakasimba kupfura

Mhando kupfura:

• nokukurumidza, kana Rapid-kupfura (32-200 K / a) riri kuitwa mureza midziyo uye kuti mumugomo mashandiro inoratidza kufambira firimu;
• mukuru-nokukurumidza kupfura 200-10 ane kakawanda 000 kusvika / kubva vaipa chichiitwa yunifomu inofamba firimu pamwe Manyiminya uye yemagetsi evanhu nzira nekupenya. Nokukurumidza Nhungirwa vari Handheld kubva zvinofamba motokari ine nyanzvi kana mudzidzi kwakajairika midziyo pamwe pakutsanangura Frequency siyana inodiwa kuti mufananidzo hachichinji.

kinosomok Technology kuramba anenge kuchinja kubvira 1955 gore, kunze ndiko kusikwa wemagetsi shutter, asi mufananidzo zvino ndee kwete firimu uye pamusoro kutevedzana kwezviitiko digitaalinen matrices, nokudaro kuona munhu furemu yevanhu mamiriyoni 100 pasekondi yoga yoga.

Mwero kumhanyisa iri kungogumira kamera aro marongerwo uye nesimba. Nokuti mudzidzi midziyo kunoratidzwa nokukurumidza kupfura - 64-72 f / s, nokuti nyanzvi - kusvikira 360-600 / s. Modern Makamera vanokwanisa kupa kakawanda 200 / s wayo zvishoma nezvishoma nokuwedzera kuti vawane rinokosha mugumisiro akauraya unodiwa. Kana uchida mamwe kumhanyisa, ipapo kuita kuchinja mapuranga ari firimu.

furemu Rate

Pane nzira dzakasiyana yokupfura mune zvesayenzi ndikarangarira Cinematography, kunyanya zvidzidzo zviri kupera mananara uye muitiro. Mumwe wavo ari kumhanya, kana Rapid-bara, pane imwe kakawanda mapuranga anopfuura 250 pasekondi yoga yoga, izvo zvinoita kuti mufananidzo pezvakaitwa dzisingambosvikiki maonero evanhu ziso nokuda pfupi nguva kumhanya kana zvakavapo.

Kuwanda tsvakurudzo zvivako ingasanganisira:

• inofamba zvipenyu: pamatanda mwero iri kubva 100 kusvika 300 K / s, kusvina - 1/1000;
• mashandiro zvigadziriswe (1-10000 K / s);
• kuparadza uye kuputika (10-100 zviuru K / s);
• gasi kugwinha chinozunguzirwa (100,000 - mamiriyoni 1 ne / s);
• yemagetsi buditsa (mamiriyoni 10-100 f / s) uye zvakafanana.

Technical mazano

Siyana ezvinhu, zvakawanda Hardware uye kakawanda zvakasiyana, zvinobvira nyanzvi videography yepamusoro zvivako. High Michina midziyo kuwedzera mureza mufananidzo kubudiswa mashandiro uyewo anoshandisa Manyiminya boosters, anokurumidza kusunungurwa fasteners yemagetsi uye Manyiminya transducers.

A mukuru-nokukurumidza kutora mifananidzo yetumedu rinoitwa kazhinji pulsed zvinyorwa chiedza (kubuda nemwenje, chiedza matsime nenyunje, dzomoto Makwanza pamwe mhepo penguva).

Chronophotography - zvenguva pakati Photo-imprinting nzira uye filming mananara akatevedzana maitikiro vachishandisa kutenderera mutswe shutter. The zvichiguma mifananidzo vari laminated pamusoro mumwe uye ikashandiswa kuva chete tepi. Nzira inoshandisa chinoramba inofamba pakati chinhu. Unique Migumisiro chinopa rakavhurika izvo pamwe nokupenya chiedza.

Nzira dzekufambisa mukuru-nokukurumidza filming

1. Rabva pamusoro intermittently kutamira firimu rinoitwa panguva kakawanda 600 / s vachishandisa zvokuimba firimu nezvifambiso zvinosvika.
2. More cranking ari kakawanda 1000 / s iri rakatangwa kushandisa pneumatic mano kana firimu mufambo nokuda kwakavharwa nenyama zvamagonhi kuti akaumba nokuda firimu makwara.
3. zvinokambaira photosensitive zvinhu zvinoshandiswa kuzadzisa yepamusoro frequencies.

Usapfuura mugumisiro anotevedzana transformations zvinogoneka chete misha iri firimu hama kuti chinhu nenzira dzinotevera.

Electronic nokuchinja

A nzira umo mutswe unotemwa obturators kuti dzisina nguva dzokuteerera. Kwenguva pfupisa nguva puranga zvaizopedza hama kuti Manyiminya mufananidzo hakurevi kusapfuudza bvumidzwa akamhanya negativity. Zvinoda inoratidza jekeso kupomba watsemuka (10-7 nguva chechipiri) kana nechokumusoro kwerwizi yevashandi connector vharafu obturator akafanana, asi anogona pachinzvimbo kuva duku mutswe notch (imwe kana dzakawanda).

Manyiminya nokuchinja

Kana cranking achiri mufananidzo kunosanganisira hwakanyatsorwisa yakafanana kufambira firimu, zvakakodzera neutralize kuwanda dzokuteerera zvaizopedza hama kuti mufananidzo svetovospriimchivogo zvinhu nokutamira chiedza tichifungisisa Manyiminya ezvinhu kushanda pane imwe nokukurumidza uye akananga firimu racho.

To dzika Manyiminya muripo girazi polyhedron suit, girazi ndiro kana prism kufamba. Kukura uye nzvimbo Manyiminya chinhu anofanira nechokwadi kuti Linear misha kwebasa mapuranga. Film Pfekenura zvinofanira kuiswa pemvura polyhedron iri rinokosha mugero kufirimu. Nzira inoshandiswa nokuda yakaderera-chinzvimbo chepamusoro.

The muganhu pa dzakakwirira frequencies elektrokommutatsii dzisina mukana kuderedza penguva pakati kupenya, uye kana Manyiminya - kumhanya vachishandisa kutenderera vharuvhu Disc wayo dhayamita.

tava kuderera fungidziro

Nokuti ziso chidzitiro kuona kunonoka inofamba unoshandiswa, uri sevanobvira zvakawedzera kakawanda filming, uye panguva deceleration kufamba firimu iri purojekita. Zvakaipira ndechokuti pachena discontinuity, uye vamwe pezvakaitwa mukuru-nokukurumidza kazhinji kusiyira pameso, zvakavigwa pakati kwepfuti filmed panguva kupfura. Kana deceleration kunopfuura 1 f / s, nemuenzaniso mufananidzo afanane yemasiraidhi dzinoratidza. Naizvozvo, chinhu optioneel slowdown kuramba kutsiva zvakasimba kupfura.

Modern nenyanzvi filming

1. Modern Makamera vakapakata wemagetsi pakudzikamisa hurongwa, asi Qualitative overcranking vakasikwa vaine achitsigirwa chinjika urefu, "monopod" kupa mufananidzo kugadzikana pasina ichidedera.
2. Vertical zvinhu uye lateral puranga mativi inofanira kufanana.
3. nzira dzakadai mavhidhiyo footage, ive alternation dzepedyo-pamwe diki uye unosvikirwa, vanoonekwa maitiro akanaka. Sverhupotreblenie scalability kuneta ari Fafitera, saka zviri nani dzimwe nguva kumisa kurekodha, filming kushandura kusvika zvakakodzera, uye ipapo mberi.
4. The optimum nguva kuti maonero pebindu anoonekwa kuti mumasekonzi anenge 5, kunonyanyisa - 12 chokuchengetedza liveliness uye dynamism yacho footage.
5. White Balance marongero ari artificially aibvira nzvimbo inokurudzirwa kuitwa manually.
6. The jengachenga mutsetse - kwete yokupedzisira chinhu chinosiyanisa nyanzvi video: zvinofanira kuitika pachiyero pakati viewfinder mutsetse kana zvishoma pamusoro. Zvinhu izvo yokumusoro chikamu pamatanda nzvimbo yokudenga inogarwa 2/3, kuti voltage vakanzwisisa.
7. Kuti orutivi Vhoriyamu svikiro uye guru kukura pamberi izvo zvinogona kuiswa chero nyaya, nemanomano ndinosika mufananidzo kudzika uye pamwero chifananidzo.
8. Kana iwe sarudza kamera angled kupfura vanofanira kufunga maonero akasiyana, mukupfuura pfungwa Somuenzaniso, kuratidza chinhu kubva vateereri uye "vatongi", uyewo kuburikidza meso ane kunze mucherechedzi. Uye danho rimwe nokuti opareta - rinokosha chitsva chacho umhizha uye itsva kuwanikwa sezvavanomutsa ayo mwero.

Tinofanira kutaura nyanzvi nezvetsika: Munguva zviitiko huru haasi akawanda pavanogona pfungwa, izvo yakakodzera abudirire kupfura, saka ngwarirai zvose zvakafanira ezvinhu pachine.
