Ukudubula Rapid - Rapid. Film okanye ividiyo adubula kumaza-32 ukuya 200 ngesekhondi. ngekhamera Professional

Express (rapidnaya) bhanyabhanya ezineqondo ngaphezu umgangatho (24 f / s) isetyenziselwa ukwenza isiphumo isindululo kade, leyo imfuno kwi ezayo bhanya, umabonwakude, imidlalo yevidiyo, cinema lwenzululwazi kuzo. Isetyenziselwa injongo yokufaka iziganeko zemidlalo, ngenxa yokudlala izinto ubeko sindululo okanye iziganeko zendalo ngokutsho kwisikali ixesha elimisiweyo. Kwi iskrini eboniswa ngengqondo ngeziganeko yokudodobala shot, kwaye kule meko umbukeli unikwa ithuba lokuba ingqalelo iinkqubo kwisigaba wethutyana iindawo kakuhle distinguishable.

Iimpawu sokudubula fast

Iintlobo lokudubula:

• olungongezwanga, okanye Rapid-zokudubula (32-200 k / a) ikhutshwa phandle izixhobo umgangatho yaye ibhakede indlela intshukumo uveza ifilimu;
• edubule-ngesantya esiphezulu 200-10 kunye rhoqo 000 / ukusuka isiqinisekiso eqhubekayo efanayo umboniso motion kunye iindlela ezisebenzisa amandla electronic nokuqhathwa kukukhanya. ihlumelo Accelerated ukuba i Pilot ukusuka isithuthi ihamba kunye izixhobo yesiqhelo yobungcali okanye engahlawulwayo kunye uluhlu frequency eyongezelelweyo efunekayo ukuze umfanekiso uzinzo.

kinosomok Technology ahlale phantse zingatshintshi ukususela kunyaka-1955, ngaphandle ke ukudala shutter elektroniki, kodwa ngoku nomfanekiso esisigxina hayi kwi ifilimu kulandelelwano ngokwematrisi digital, ukuqinisekisa izinga kwisakhelo 100 million ngomzuzwana.

Degree of unikezelo kuphela lwecamera ngu isakhiwo sayo kunye neentshukumo. Kuba izixhobo engahlawulwayo luphawulwa ukudubula okukhawulezileyo - 64-72 f / s, ngokuba umsebenzi - ukuya 360-600 / s. iikhamera Modern banako ukunika amaza 200 / s neendyebo zalo kancinane ukuze bafumane ekhethekileyo isiphumo rate umbulele. Ukuba ufuna ukukhawulezisa ngakumbi, koko wabhenela ukusetyenziswa kwizakhelo kwi ifilimu.

isakhelo Rate

Kukho nezabelo ngezabelo sokudubula Cinematography yenzululwazi kunye siwasebenzisa, ingakumbi izifundo iziganeko bufutshane yaye neenkqubo. Enye yazo nodibaniso olunesantya esiphezulu, okanye Rapid-shot, kumaza abangaphezu kwama-250 ngesekhondi, nto leyo evumela lokufotha iinkqubo Umbono wefilosofi iliso ngokwabantu, ngenxa yokuba ixesha nesantya elifutshane aphezulu okanye iziganeko ngamnye kule.

Inani lamaziko uphando ziquka:

• motion of eziphilileyo: izinga Isakhelo ukusuka 100 ukuya 300 K / s, Kucatshulwe kwisiCwangciso - 1/1000;
• iindlela zokusebenza (1-10000 k / s);
• intshabalalo kunye neziqhushumbisi (10-100 amawaka k / s);
• shoka gas wave (100,000 - 1 million nge / s);
• khulula yombane (million 10-100 f / s) kunye like.

tricks technical

Ezahlukeneyo iimeko, kukho uluhlu olubanzi lwempahla zentsimbi kunye amaza ombane, kunokwenzeka ngekhamera nobungcali izibonelelo ezikumgangatho ophezulu. izixhobo zobuchwepheshe High ukongeza yindlela esezantsi umfanekiso processing kwakhona iqeshe zizomelezi woqondo, ngokukhawuleza-ukukhululwa zokubopha, transducers elektroniki nezibonwa.

A nokufotwa-high speed wenziwa ngokuqhelekileyo eziphuma idaleka ukukhanya (izibane obhobhozayo, imithombo ukukhanya kwakho imbabala, izikhewu ilangatye kunye kwisithuba lomoya).

Chronophotography - oluphakathi phakathi kwe indlela photo-imprinting ngezimanga bhanyabhanya ngokwezigaba ezilandelelanayo usebenzisa batshintshana noqhoqhoqho shutter. Le mifanekiso ukuba ngaplastiki kwi omnye komnye kwaye zidityaniswe zibe tape enye. Indlela isebenzisa isiphakamiso rhoqo kwesi into. imiphumela Unique inika se evulelekileyo kunye ukukhanya flash.

Iindlela ye-high speed bhanyabhanya

1. Eyayikrolwe ifilimu nqapha ochukumisayo ziqhuba rhoqo 600 / s ngokusebenzisa inkqubo yezothutho umboniso ngoomatshini kwi.
2. cranking ngakumbi kumaza ka-1000 / s usebenzisa izixhobo anomoya okanye ifilim ukuhamba kwi ngenxa kwiihenjisi elastic ukuba kwabunjwa channels film.
3. ezihambayo izinto photosensitive asetyenziselwa ukuphumeza phezulu.

Zinto zimbi ifuthe utshintshwano ngalinye kunokwenzeka kunye ukubana ifilimu kuthelekiswa nto ngezi ndlela zilandelayo.

ziguquka electronic

A indlela apho noqhoqhoqho yi obturators aqingqiweyo amaxesha elilinganiselweyo sesichengeni. Okwelona xesha lifutshane benqwanqwa ixesha offset kuthelekiswa kumfanekiso woqondo aluwudluli kweso kelwa obuvumelekileyo. Kufuna ukhanyiso uveza Ungqabhuko ukubetha (10-7 ixesha yesibini) okanye emantla kwabasebenzi Isidibanisi vana obturator efana, kodwa endaweni ibe encinane noqhoqhoqho notch (enye okanye ezininzi).

ziguquka optical

Ukuba cranking kunjalo umfanekiso ibandakanya intshukumo efanayo noko ifilimu, kuyimfuneko ukuba Nokwethisa uluhlu lwe sesichengeni offset ngokunxulumene umfanekiso svetovospriimchivogo izinto ngokushukumisa inkqubo ukukhanya iingcinga enombala ukusebenza ngesantya kwaye kwicala lokuhamba film.

Ukufezekisa imbuyekezo enombala isipili Ipolihedron isuti, kwipleyiti iglasi okanye bemilo ihamba. Ubukhulu kunye nesikhundla element woqondo kufuneka baqinisekise ukuba ukubana intshukumo yomgama izakhelo. strip Film kufuneka zibekwe phezu komhlaba Ipolihedron kwi movie channel okhethekileyo. Indlela lisetyenziswa kwinkqubo ephantsi-umthamo.

Umda kwi phezulu elektrokommutatsii ithuba eliqingqiweyo ukunciphisa lokuphumla phakathi kubaneka, kwaye xa woqondo - ubucotha ukujikele- we disc nokufakelwa ubudeki balo.

kwelivi linyuke

Kuba screen olubonakalayo ukubukela eshukumayo olucothayo iyasetyenziswa, njengoko kunokwenzeka kunye qho umboniso, kwaye ngexesha deceleration intshukumo bhanya umatshini. Esi sithintelo yeyokuba discontinuity ngathi, yaye ezinye iinkqubo-high speed ngokubanzi beyeka ebusweni, efihliweyo phakathi kuqhume ezifotwe ngexesha ukudubula. Ukuba deceleration ungaphezulu kwe-1 f / s, umfanekiso umboniso ufana show kwisilayidi. Ngoko ke, kukho ukwehla ozikhethelayo ngakumbi ukubuyisela ukudubula ukuzila.

ubuchule Modern lomsebenzi

1. iikhamera Modern nee-nkqubo gulwa elektroniki, kodwa overcranking qualitative wadala ngenkxaso enobude adjustable, "monopod" ukubonelela ngozinzo umfanekiso ngaphandle ukungcangcazela.
2. izinto ezithe nkqo kunye namacala isakhelo osecaleni kufuneka ngaxeshanye.
3. zindlela video, njengoko alternation ka n'wina-up ne ezincinane kunye neziphakathi, iyaqwalaselwa style elungileyo. Sverhupotreblenie scalability baphelelwa oyibukeleyo, ngoko ke kungcono ngamanye amaxesha ukuyeka ukurekhoda, bhanyabhanya ukuguqulela kangangoko kuyimfuneko, uze uqhubeke.
4. Ixesha elilelona ngenxa kwimbono sebali ithathwa malunga 5 imizuzwana, ubuninzi - 12 ukuze alondoloze liveliness kunye uthsintsho ye video.
5. Balance White kwigumbi zamntu Wazikhanyisa Kucetyiswa ukuba kwenziwe ngesandla.
6. Umgca lé - hayi phawu yokugqibela eyahlula ividiyo professional: ukuba kufuneka kwenzeke kwinqanaba phakathi komgca viewfinder okanye kancinci ngasentla. Imifanekiso apho inxalenye ephezulu yesakhelo isithuba wasezulwini yelungu 2/3, ukuya ombane waqonda.
7. Ukwenza iiplanga umthamo medium and enkulu ubungakanani phambi ngemehlo inokubekwa nasiphi na isifundo, Babaqhathanisele ukudala umfanekiso ubunzulu kunye nobungakanani lo mfanekiso.
8. Xa ukhetha ukudubula engile yekhamera kufuneka ingqalelo iimbono ezahlukeneyo, ukuya ngaphaya engaguqukiyo, umzekelo, bonisa into abaphulaphuli "abagwebi", kwakunye ngokusebenzisa amehlo obukeleyo ngaphandle. Kwaye inyathelo ngalinye ukuba umqhubi - isiganeko entsha ubuciko bayo kunye ukufunyanwa omtsha kuphakamisa umgangatho wayo.

Kufuneka kwakhona ukhankanye lokuziphatha: Ngethuba iziganeko ezinkulu ezininzi kangaka amanqaku usemhlabeni, afaneleka yokudubula nempumelelo, ngoko ke kufuneka uthathe unonophelo zonke iimeko eziyimfuneko kwangaphambili.
