Aperture Basics

Aperture ndechimwe chezvinhu zvakavhiringidza zvekutora mifananidzo kune vatsva vatsva (uye mamwe maoko akare). Muzvokwadi, hazvifaniri kunge zvakavhiringidza. Nzvimbo iyo inoshandura kugadzirisa mukati memamera ekamera inoshanda zvakafanana zvakanyanya muziso rako.

Apo bundu rinozarura (kufanana neziso rako rinoputika), rumwe ruedza runobvumidzwa kuburikidza ne lens kuti ruratidze pefirimu. Apo chivako chidiki (kufanana nomudzidzi wako muchiedza chakajeka), chiedza chiduku chinosvika mufirimu. Izvi zvinoshanda pamwe chete nekuvhara nekukurumidza uye firimu nekukurumidza kuti uone kuwanda kwechiedza chinosvika pafirimu. Kukura kwemafuro kunobatawo kuwedzera kwebindu .

Kuyera Kura

Aperture inotarwa achishandisa F-Stops. F-Stop nhamba inomirira chikamu chiduku chekumirira kwechiyero chechiedza chinobvumirwa kupfuura nepakati. Mumashoko akareruka, F-Stop nhamba dzinokura zvakanyanya sezvo nzvimbo inowedzera inowedzera, sekuti shutter speed numbers inowedzera sezvo nguva yevhavha yakazaruka inowedzera. Chimwe nechimwe chinowedzera F-Stop nhamba chinomirira chikamu chechiedza chinosvika mufirimu. Sezvo nzvimbo inopera, zvimwe zvechiitiko zvichasvika pakuisa pfungwa pamwe chete (sezvatakadzidza muhupamhi hwepasa chidzidzo ).

F-Stop Relationship KuChiedza nekudzika kweMunda

• Big F-Stop Number = Chimwe Chiedza Chinodiwa = Kuwedzera Kukura Kwebindu
• Little F-Stop Number = Chiedza Chidiki Chinodiwa = Chidiki Kupfuura Munda

Mifananidzo yakawanda yemifananidzo pamusoro pemakore yakaedza kukonzera pfungwa yekudzika duku = huru F-Stop kuva bhodhi vatsva vatsva. Kunyange zvazvo izvi zvichikosha kuziva, ndakaona vazhinji vemafirimu vatsva vakaora mwoyo vachiedza kurangarira hukama huri mumunda. Kana zviri nyore kuti iwe uyeuke hukama hweF-Stop kune chiedza nekudzika kwemunda ipapo nenzira dzose, shandisa nzira yekuyeuka iyo inokubatsira iwe mumunda. Kana iwe uchinge usiri kupfura nokuti iwe uri kuedza kuyeuka kuvhara kwa F-Stop mechanics zvino inongova chipingamupinyi.

Kunyange zvazvo pane chaizvo zvakasiyana-siyana zve-F-Stops (kuzarura mashizha) zvichibvira, zvichienderana nejeri rako, kune nzvimbo yakafanana yepakati pevhesi iyo manyengi emagetsi ekukwanisa anokwanisa kushanda mukati.

Kuisa Aperture

Aperture yakagadzirwa pamakamera nekushandura tsanangudzo yakananga pamuviri wekhamera. Mumakore akwegura, akazara makamera ekunyora, iyi inodhonza pamera yekamera iyo yakanyorwa ne F-Stop nhamba. Mumakera matsva, nzvimbo yacho inowanzoonekwa pane imwe svondo reLCD apo mufananidzo wacho anoshandura gumbo duku pedyo nebhokisi rekusunungura kushandura kugadzirisa hurongwa. Kunyatsosungirwa kwegumbo kuchasiyana kubva pakamera kusvika khamera. Pamusoro uye kupfura makamera, pangave pasina hutungamiri kuti usarudze zvakananga kana F-Stops.

Kana ikamera yako isina nzira yekugadzirisa manyore iwe unogona kudikanwa kuti unzwisise nzira dzako dzekamera dzakagara dzakagadzirirwa kuti uwane zvinodiwa. Vakawanda SLR makamera vanewo maitiro akafananidzwa kare uye mamwe maitiro mashoma ekudzivirira.

Mimwe Mienzaniso yeAperture-Specific Preset Camera Modes

Aperture Priority - Inokubvumira kuisa iyo uye kamera inosarudza speed shutter uye ISO

Pasi Preset - Inoshandisa nzvimbo shoma (huru F-Stop) kuburikidza

Mufananidzo wekugadzirisa - Unoshandisa nzvimbo huru (duku F-Stop) uye firimu inononoka nokukurumidza

Aperture mu Preset Camera Modes

Munenge dzose makamera matsva mazuva ano ane mamwe maitiro ekufambisa zvigadzirwa zvemafaira. Izvi zvakagadzirirwa mamiriro ezvinhu akadai sezviito, nzvimbo, uye mavara. Kana iwe uchiziva kuti aya ma modes achinje pamusoro pekugadzirisa kamera yako unogona kuvashandisa kuti iwe unobatsire mune mamwe mamiriro ezvinhu akawanda kunze kweavo vaanoda. Takafukidzira maitiro mashomanana akaremerwa zvikuru kuti atore asi zvino ngatitsvakei kuti sei nzvimbo inoshanda mune imwe preset kamera modes.

Maitiro Aperture Anoshanda Sei mu Preset Modes

Macro
Macro mode ndeyekutsvaga kuisa mode apo kamera yakagadzirirwa kushandisa ruzivo rwakakura kubhadhara kudzvinyirira kweDOF yekuvhara. Mune mamiriro aya, haugoni kuisa chairo chaunoda asi iwe unogona kuderedza mikana yako yekunze kwekutarisana nepamusoro-soro kuburikidza uchishandisa iyi mode.

Mamiriro
Mazingira mode ndeyekuti DOF yakakura. Nzvimbo yakarongedzwa kuti ipe nzvimbo duku kudarika (yakakura F-Stop) inogona kuitika kuitira kuti ive nechokwadi chekudzika kwakanyanya kwendima . Izvi zvinoreva kuti kasi yevhavha inenge ichinonoka. Kana ikamera yako isingabvumiri Bhuku kana Av mode uye iwe uri kuda kutema nyaya iyo mamiriro acho ezvinhu ari mukutarisa, edza nzvimbo yekugara.

Mufananidzo
Portrait mode inoshandisa nzvimbo yakakura kuti iumbe DOF duku. Mifananidzo inorongwa kuti ive nehupamhi hwemunda (hurukuro yakakura / duku F-Stop) uye shandisa pfuurimu firimu nekukurumidza kuitira kukanda mamiriro ekunze kunze kwekutarisa uye kuwana yakaisvonaka mafirimu yezviyo. Shandisa iri sarudzo chero nguva iwe uchida ruvara rwakashata.

Manual
Bhuku rinogadzirirwa rakanyorwa "M" pane makamera matsva uye, chaizvoizvo, rinongogadzirirwa pamakamera ekushandisa. Manual mode zvinoreva kuti iwe wakanyatsogadzirisa zvirongwa zvekhamera yako. Kana iwe ukasarudza kuvhara / F-Stop paM M maitiro, iwe uchada kugadzirisa kuvhara faster iwe pachako kuitira kuti uchengetedze kuratidzwa kwakarurama. Shandisa mera yemamera yekera yako kuti uone kuti mararamiro akaenzana.

Aperture Priority
Kugadzikana kwekhamera yako yakanzi "Av" inonzi Aperture Priority mode. Izvi zvinoreva kuti kana iwe ukashandisa Av mode uye uise iyo yekuvhara / F-Stop, kamera ichagadzirisa yako shutter speed value kuti uchengetedze kuratidzwa kwakarurama.

Purogiramu
Programme mode inoratidzwa ne "P" pane makamera mashoma ane izvi. Mune purogiramu yemafungiro, kamera yako inopindura kune dzimwe mamiriro ekugadzirisa wawakaronga mumenyu. Kazhinji, iyi mode inokubvumira kuti ugadzire kana mushure wekuvhara kana kuvhara apo kamera inogadzirisa imwe nzvimbo kuitira kuchengetedza zvakakodzera.
