Kamera yeDigital Resolution ye20MP
Munguva iyo makamera ari kwese kwese, izwi rekuti "megapixel" (MP) rinowanzo shandiswa pakuongorora mhando yemufananidzo. Vanhu vazhinji vanofunga kuti kana megapixel yakawanda, mufananidzo wacho unowedzera kunaka. Zvisinei, chokwadi chiripo chakaoma kunzwisisa. 20MP (20 megapixel) resolution pane kamera yedhijitari inzvimbo yakakurumbira yepakati: yakakwirira zvakakwana pakudhinda, kutsanangura, uye kucheka, asi ichiri yechokwadi pakugadzirisa nekukurumidza uye saizi yefaira. Chinyorwa chino chinokurukura zvinorehwa ne20MP, zvakanakira zvayo uye zvisingakwanisike, uye kuti resolution iyi inonyanya kunzwisisika riini.
Chii chinonzi 20MP?
Megapixel iyuniti yekuyera huwandu hwemapikiseli ari pachinzwa chekamera. 1 megapixel inomiririra miriyoni imwe yemapikiseli. Saka, kamera ye20MP inogona kutora ruzivo rwemifananidzo inosvika mamiriyoni makumi maviri mumufananidzo mumwe chete. Resolution iyi inowanzoita kuti mufananidzo uve nehukuru hwemapikiseli angangoita 5472 × 3648 (kunyange izvi zvichigona kusiyana zvichienderana nechiyero chesensa, senge 3:2 kana 4:3). Izvi zvinoreva kuti mufananidzo une ruzivo rwakakwana rwekushandiswa kwakasiyana-siyana, kubva pamashoko epasocial media kusvika kumapikicha makuru.
Zvisinei, zvakakosha kunzwisisa kuti ma megapixels chete haasarudze mhando. Sensor, lenzi, kugadzirisa mifananidzo, saizi yema pixel, uye mamiriro ekupfura zvine basa guru. Kamera ye20MP ine sensor hombe ne lenzi yepamusoro inogona kugadzira mapikicha ari nani pane kamera ye48MP pafoni ine sensor diki uye inogadziriswa zvine simba.
Hunhu Hwakajeka uye Kujeka
Mukuita, 20MP inopa kuenzana kwakanaka kwekupinza uye ruzivo rwakadzama. Unogona kutora mifananidzo iri pachiratidziro, uchinyatsoongorora magadzirirwo ezvipfeko, mashizha, kana ruzivo rwezvivakwa. Pakutora mifananidzo yenzvimbo, kufamba, magwaro ezviitiko, uye mafoto, 20MP inowanzo kukwana.
Kupinza kwekupedzisira kuchiri kukanganiswa ne lenzi. Kamera ye20MP ine lenzi ye kit yakajairika ichaita zvinhu zvakanaka, asi kana ikabatanidzwa ne lenzi yepamusoro (semuenzaniso, lenzi ye professional-grade prime kana zoom), kugona kwe 20MP resolution kunogona kuwedzerwa. Uyezve, matekiniki ekupfura akadai sekushandisa shutter speed yakakwana, kutarisisa kwakaringana, uye kugadzikana zvinosarudzawo kana zvinhu zve 20MP "zvichioneka" zvechokwadi kana kuti zvakarasika nekuda kwekusviba.
Kuchinjika Kwekucheka
Chimwe chikonzero chinoita kuti vafotori vazhinji vade ma resolutions anosvika 20MP ndechekuti inokwanisika here kana uchitora mifananidzo yemhuka dzesango kana mitambo, haugone kugara wakanangana nemunhu wauri kutora mifananidzo. Ne 20MP, unogona kutora mifananidzo nechisimba uku uchiramba uine resolution yakakodzera kuratidzwa nedhijitari kana kuti mifananidzo midiki kusvika pakati.
Zvichitaurwa zviri nyore, kana ukacheka foto nepakati, resolution inodzikirawo nehafu. Kubva pa20MP kusvika pa10MP, izvo zvichiri zvakanaka kuti zvishandiswe online uye kunyangwe pamaprints epakati nepakati. Nemamwe mashoko, 20MP inopa "nzvimbo yakachengeteka" kune avo vanogara vachichinja mafoto mushure mekutorwa.
Saizi Yefaira uye Zvinodiwa Zvekuchengetedza
Kugadziriswa kwacho kunoenderana nehukuru hwefaira. Mufananidzo we20MP mufomati yeJPEG unowanzova pakati pe4–10 MB, zvichienderana nekudzvanywa uye ruzivo rwemufananidzo. Panguva imwe chete, faira reRAW rinogona kusvika 20–30 MB kana kupfuura, zvichienderana nerudzi rwekamera uye kudzika kwebit.
Izvi zvinokanganisa zvinodiwa nemakadhi ekurangarira, kugona kwedhiraivha yakaoma, uye mashandiro ekugadzirisa. Zvichienzaniswa nemakamera e40–60MP, makamera e20MP anowanzo shanda zvakanaka. Kupinza, kuongorora, uye kugadzirisa palaptop iri pakati nepakati kazhinji kunonakidza. Kune vanotora mifananidzo vanotora mazana kusvika kuzviuru zvemifananidzo panguva imwe chete (semuenzaniso, pamichato kana zviitiko), saizi diki dzemafaira dzinochengetedza nguva nenzvimbo yekuchengetera.
Kukwanisa Kudhinda: Kudhinda Kwakakura Sei?
Chiyero che20MP chakakwana zvakakwana pakudhinda. Chiyero chinowanzoonekwa chekudhinda kwepamusoro-soro i300 dpi (madots pa inch), kunyange zvazvo kune maposta anoonekwa ari kure, 150–200 dpi inowanzo kukwana.
Ne resolution ye5472 × 3648 pixels, unogona kudhinda nepfungwa:
- Inenge 12 × 18 inches pa300 dpi (hunhu hwakapinza kwazvo)
- Yakakura zvakanyanya pa200 dpi, yakakodzera maposta kana mawall displays
Mukushandiswa kwezuva nezuva, 20MP inobvumira kudhindwa kwemifananidzo yemhuri, maportfolio, uye kunyange zvinhu zvekushambadzira pasina kunetseka. Kunyangwe kune mamwe mashandisirwo ebhizinesi, 20MP inoramba iri chiyero chakachengeteka, kunyanya kana mwenje nekushandisa pfuti zvakanaka.
20MP uye Saizi yeSensor: Kubatana Kusingawanzonzwisiswi
Kuwanda kwemaMegapixel kunowanzoonekwa sechiratidzo chemhando yesensa, asi saizi yesensa inokoshawo. Sensa ye20MP yakazara ine 20MP inowanzova nemapikiseli akakura kupfuura sensa ye20MP micro four-thirds kana 1-inch (kunyange zvisiri nguva dzose, zvichienderana nekugadzirwa kwayo). Mapikiseli akakura anowanzo tora chiedza chakawanda, zvichikonzera kushanda kweISO kwakanyanya uye dynamic range.
Ndosaka makamera e20MP ane furemu yakazara achiwanzoita zvakanaka mumamiriro ekunze asina chiedza chakawanda, zvichiita kuti ruzha ruve rwakaderera uye mumvuri wakajeka. Kunyange zvazvo makamera e20MP ari pamasensa madiki achiri akanaka, angangoda chiedza chakanyanya kunaka kana marongero chaiwo ekuderedza ruzha.
Kumhanya Kwekuita: Kuputika, Autofocus, uye Vhidhiyo
Kureba kwakaderera kunopa mukana wekumhanya. Makamera e20MP, kunyanya makamera asina magirazi kana DSLR akagadzirirwa kushanda, anowanzo kwanisa kupfura maburst ane frame rates yakakwira uye mabuffers akakura. Nekuti faira rega rega diki pane kamera ye30–60MP, kamera inogona kunyora data kumemori kadhi nekukurumidza uye kuchengetedza burst kwenguva yakareba buffer isati yazara.
Pamavhidhiyo, 20MP resolution yakanakawo, sezvo vhidhiyo ye4K inongoda 8,3MP pafuremu imwe neimwe. Ne sensor ye20MP, kamera inogona kuita oversampling kana cropping yakayerwa kuti ibudise 4K yakapinza. Makamera mazhinji anozivikanwa mumusika wekutora mifananidzo yezviito kana mapikicha anoshandisa resolution iyi, sezvo ichionekwa seyakaenzana zvakanaka kune zvese zvinodiwa.
Muganho weKugadziriswa kwe20MP
Kunyange zvazvo ichishanda zvakasiyana-siyana, 20MP ine miganhu yayo. Kana uchigara uchitora mabhodhibhodhi, mapikicha makuru ane mapikicha ari pedyo, kana uchida kuchekwa zvakanyanya, kamera ye30–60MP inogona kubatsira. Mimwe mifananidzo yezvigadzirwa, kudhirowa mifananidzo, kana basa rekutengeserana rinoda ruzivo rudiki dzimwe nguva rinogonawo kuva nyore kana riine resolution yepamusoro.
Zvisinei, zvakakosha kuyeuka kuti kuwedzera ma megapixels kunodawo ma lenzi, matekiniki, uye kugadzikana. Kugadzirisa kwakakwirira kunoita kuti zvive nyore "kuratidza" zvikanganiso: kunyangwe kusanyatso tarisa, kusviba kudiki kunokonzerwa nekukwazisana nemaoko, kana lenzi isina kupinza zvichaonekwa zvakanyanya.
Kamera ye20MP Yakanakira ani?
Chisarudzo che20MP chakakodzera:
1. Vatori vemifananidzo vanoda mifananidzo yakanaka vanoda mhando yepamusoro isina mafaira akakura zvakanyanya.
2. Vatori vemifananidzo yezviitiko/michato vanotora mifananidzo yakawanda uye vanoda nguva yekushanda nekukurumidza.
3. Vanoda kufamba vanoda ruzivo rwakakwana rwekudhinda nekunyora magwaro.
4. Vatori vemifananidzo vezviitiko zvechiito nemhuka dzesango vanoda kutorwa mifananidzo nekukurumidza uye kutemwa kwakakwana.
5. Vagadziri vezviri mukati vanosanganisa mapikicha nemavhidhiyo e4K mumudziyo mumwe chete.
Kune vazhinji vashandisi, 20MP haisi "yakakwana" chete, yakakwana zvakakwana. Chinangwa hachifanirwe kunge chiri chehuwandu hwemamegapixel chete, asi pane system yese: mhando yelenzi, kugona kwe autofocus, kugadzikana, ergonomics, uye mhando yeruvara.
Mhedziso
Kamera yedhijitari ine resolution ye20MP inopa chiyero chakakwana cheruzivo, kuchinjika, uye kushanda zvakanaka. Inobvumira kuchekwa, inobvumira kudhinda kwemhando yepamusoro-soro, uye inoita kuti saizi dzemafaira dzirambe dzakaringana. Panguva imwe chete, 20MP haimanikidze hardware nemabasa ekushanda semakamera ane resolution yepamusoro-soro.
Pakupedzisira, kamera yakanakisisa haisi iyo ine ma megapixel akawanda, asi iyo inonyatsokodzera zvaunoda. Kana uchida mapikicha akajeka, kugona kudhinda kwakasimba, uye kushanda zvakanaka, kamera yedhijitari ye20MP isarudzo yakakosha zvikuru—kunyangwe pakati pehuwandu hwema megapixel huri kuramba huchiwedzera.
