Ladislav Soukup Hondo yemegapixel yemakompakiti makamera yatove tsika yakajairika, asi nharembozha hadzina kutora chikamu zvakanyanya. Mazhinji nharembozha dzinogara dzakadzikira maererano nemamegapixels uye dzinoguma dzakatenderedza 8 Mpix. Asi chii chinonyanya kukosha pamifananidzo yemhando? Ko 41 Mpix inodiwa chaizvo?
Sensors
Mhando uye kugadzirisa kwe sensor kwakakosha, asi kune imwe nhanho. Unhu hwechikamu chemaziso chinoitawo basa guru, iro ndiro dambudziko guru nefoni. Kana iyo optics isiri yemhando yepamusoro, kunyangwe kugadzirisa kwe100 Mpix hakukuponese. Kune rimwe divi, kuseri kwemhando yepamusoro optics, sensor ine resolution yepamusoro inogona kungoratidza. Chimwe chiratidzo chakakosha kunze kwekugadziriswa imhando ye sensor pamwe nekuvakwa kwemafotocells.
Iyo inonakidza tekinoroji zvakare Sensor yakavhenekerwa kumashure, iyo Apple yave ichishandisa kubva pa iPhone 4. Zvakanakira ndezvokuti rudzi urwu rwe sensor runogona kutora inenge 90% yemafotoni, panzvimbo yenguva dzose 60% ye classic CMOS sensor. Izvi zvakaderedza zvakanyanya mwero weruzha rwedhijitari iyo CMOS sensors inowanzotambura nayo. Icho chimwe chiratidzo chakakosha chehutano. Mumamiriro asina kunaka ekuvhenekesa, ruzha runoonekwa nekukurumidza mumufananidzo uye runogona kukanganisa zvakanyanya kunaka kwemufananidzo. Uye iyo yakawanda megapixel munzvimbo diki (kana iyo idiki sero sensor), iyo inonyanya kuoneka ruzha, chiri zvakare chikonzero chikuru nei mafotomobiles anowanzo kunamatira pasi muhondo yemegapixel, uye Apple yakanamatira ku4 Mpix neiyo iPhone. 5 uye chete neiyo iPhone 4S yakachinja kuenda ku8 Mpix, uko iPhone 5 yakasara.
Ngatirodzei
Iko kugona kweiyo optics kutarisa kwakakosha zvakare ... munguva yakapfuura (iPhone 3G) iyo lens yakagadziriswa uye kutarisa kwakagadziriswa kune imwe nzvimbo - kunyanya pa hyperfocal chinhambwe (kureva kudzika kwemunda kunopera chaiko infinity uye inotanga padyo nekamera sezvinobvira) . Nhasi, huwandu hwakawanda hwemafoni ekhamera achinja kune optics inokwanisa kutarisa, Apple yakazviita neiyo iPhone 3GS ine iOS 4.
Digital kamera
Chimwe chikamu chakakosha ndeye processor yemufananidzo, iyo inotarisira kududzira iyo data kubva kune sensor kuenda kune inoguma mufananidzo. Varidzi vedhijitari SLR kamera vangangove vakatojairana neRAW fomati, iyo "inodarika" iyi processor uye inoitsiva chete nesoftware pakombuta (asi mazuvano zvakare pamapiritsi). Iyo processor yemufananidzo ine basa rezvinhu zvakati wandei - bvisa ruzha (software), chiyero chena (kuitira kuti toni dzemavara dzienderane neicho chaicho - zvinoenderana nekuvhenekera mumufananidzo), tamba ne tonality yemavara mumufananidzo (girinhi uye bhuruu saturation inowedzerwa kune nyika, nezvimwewo ...) , gadzirisa mutsauko wemufananidzo uye zvimwe zvigadziriso zvidiki.
Kune zvakare masensa ane chaiwo 40 Mpix uye anoshandisa "chitsotsi" kuderedza ruzha... Pixel yega yega inopindirwa kubva kune akawanda mafotocell (pixels pasensor) uye mufananidzo processor inoedza kurova iro ruvara uye kusimba kwepixel iyoyo. . Izvi zvinowanzoshanda. Apple haisati yasvika maitiro akafanana, uye saka inoramba iri pakati peari nani. Imwe nzira inonakidza yakaonekwa nguva pfupi yadarika (uye haisati yashandiswa mukuita nechero photomobile) - Dual ISO. Izvi zvinoreva kuti hafu ye sensor inotarisisa nekunzwa kwakanyanya uye imwe hafu ine kushoma senitivity, uye zvakare inokonzeresa pixel inopindirwa uchishandisa mufananidzo processor - iyi nzira ingangodaro yakanyanya kunaka kudzvinyirira mhedzisiro kusvika zvino.
Zoom
Iyo zoom zvakare chinhu chinoshanda, asi zvinosuruvarisa kuti haisi yekutarisa panharembozha, asi kazhinji ingori dhijitari. Optical zoom zviri pachena zvirinani - hapana kuderedzwa kwemufananidzo. Digital zoom inoshanda seyakajairwa mafoto kudzvanya, i.e. mipendero inochekwa uye mufananidzo wobva waonekwa wakakurisa; zvinosuruvarisa nekurasikirwa kwehutano. Vamwe vagadziri vanoenda nenzira ye40 Mpix sensors, pane iyo dhijitari yekudyara iri nyore - pane zvakawanda zvekutora kubva mairi. Iyo foto inokonzeresa inozoshandurwa kubva padanho repamusoro kusvika padanho rekuti 8 Mpix.
[ita chiito=”citation”]Mufananidzo wakanaka hauitwe nekamera, asi nemutori wemifananidzo.[/do]
Kunyangwe mune iyi kesi hapazove nekudzikira kwakakosha kwekugadziriswa (mushure mekuchengetedza, iyo foto inogara iri diki pane chaiyo nhamba yemapoinzi pane sensor), pachave nekudzikira padanho re sensor, uko mapoinzi ega ega ari madiki uye nekudaro. kuderera kuchiedza, izvo zvinosuruvarisa zvinoreva ruzha rukuru. Asi kazhinji haisi nzira yakaipa uye ine musoro. Tichaona kana Apple ichitevera sutu neiyo iPhone nyowani. Neraki kune iyo iPhone, kune akati wandei anobviswa lenses anogona kuwedzera optical zoom ine mashoma maitiro pamhando - hongu, zvakawanda zvinoenderana nemhando yezvinhu zvemaziso.
mheni
Pakutora mafoto murima, nharembozha zhinji nhasi dzatoshandisa "flash", kureva chena LED diode, kana xenon flash. Muzviitiko zvakawanda inoshanda uye inobatsira, asi mukutora mifananidzo kazhinji, on-axis flash inoonekwa sehutsinye hwakaipisisa. Nekune rimwe divi, kushandiswa kwemwenje wekunze (yakakura uye inorema kupfuura nhare mbozha) hazvigoneke, saka off-axis flash icharamba iri dura rehafu-nyanzvi uye nyanzvi DSLR vatori vemifananidzo kwenguva yakareba. Asi izvi hazvireve kuti iyo iPhone haigone kushandiswa pakuita mafoto padanho rehunyanzvi Mushure mezvose, zvitarisire iwe pahunyanzvi hwekutora mifananidzo neiyo iPhone 3GS.

Chimiro chemufananidzo
Izvo zvinotisvitsa kune dambudziko guru: "Ini handigoni kutora mufananidzo wakanaka zvakadaro pasina kamera inodhura Yakashata." Unogona. Mufananidzo wakanaka hauitwe nekamera, asi nemutori wemifananidzo. Iyo digital SLR kamera ine inodhura mhando lens ichagara iri nani pane nhare mbozha, asi iri mumaoko emutori wemifananidzo ane ruzivo. Mutori wemifananidzo akanaka achatora mufananidzo uri nani nefoni mbozha pane vazhinji vasiri mafoto ane inodhura SLR kamera - kazhinji zvakare kubva pahunyanzvi hwekuona.
Isu tinogovana mifananidzo
Mukuwedzera, mukana mukuru wemafoni efoni uye iOS muhuwandu huwandu hukuru hwezvikumbiro zvekugadzirisa mapikicha uye kugoverana kwavo nyore uye nekukurumidza, iyo iOS pachayo inogara ichivandudza nekuwedzera. Mhedzisiro yacho ndeyekuti iyo foto kubva ku iPhone yakagadzirira uye yakagovaniswa mumaminetsi mashoma, nepo rwendo kubva kuSLR kamera kuenda kumasocial network inotora maawa akati wandei (kusanganisira rwendo rwekuenda kumba uye kugadzirisa). Migumisiro inowanzofanana zvikuru.
Iyo yakavakirwa-mukati app muIOS inonyatso inokwanisa pachayo. Kune vanonyanya kuda vashandisi, kune zvakare boka rakakura rezvishandiso rakanangana nevashandisi vepamberi vane huwandu hukuru hwesarudzo. Chishandiso chinopa zvimwe mikana yakawanda PureShot, ane wongororo yatiri kugadzirira iwe. Isu tinobva tave neseti yechipiri yemaapplication aripo ekugadzirisa mafoto. Boka rakaparadzana zvikumbiro zvinotsigira zvese kutora mafoto uye kunotevera kugadzirisa - semuenzaniso, zvakanakisa Camera +.
Pamwe chete chinodzikisira che iPhone ndechekutarisa… ndiko kuti, kugona kutarisa nemaoko. Kune mafoto kana iyo neimwe nzira yakanaka kwazvo autofocus ikatadza uye zvave kusvika kune hunyanzvi hwemutori wemifananidzo "kunzvenga" zvipimo uye kutora foto. Hongu, ndingadai ndakatora mufananidzo uri nani neruzha rushoma neSLR kamera uye macro lens, asi kana ndichienzanisa iyo iPhone uye "yakajairika" compact kamera, mhedzisiro yatove pedyo zvakanyanya, uye iyo iPhone inowanzokunda nekuda kwekugona. kugadzirisa uye kugovera iyo foto nekukurumidza.
Ini pachangu, ndinofunga zvakanyanyisa kuenzanisa mutori wemifananidzo ane iPhone VS mushandisi asina ruzivo nehunyanzvi SLR kamera. Kana mumwe munhu akatenga semi-nyanzvi SLR ine mhando lens, haisi yekutanga, asi zvirinani. mutambi anozove ne100x mapikicha ari nani pane nyanzvi yekutora mifananidzo ane iPhone. Hazvisi pasina kuti ndakaratidzira mune imwe yemifananidzo yevatori vemifananidzo kuti vanofanirwa kushandisa maPhones pachinzvimbo cheSLRs uye kuti vanonyara nebasa ravo. Chero ani akaona kufananidzwa kwemafoto kubva kumushumo iP VS SLR anoziva zvakanyanya kukurumidza kudonha kwemhando. Muvhidhiyo iri muchinyorwa, mutori wemifananidzo anowana iPhone yekupfura mafoto, asi haasati arambidzwa kushandisa michina inodhura ye studio, kusanganisira iyo yakanaka modhi :D Ndinoshamisika kuti aizoita sei kana aingotora mifananidzo usiku. pasi pemwedzi nenyeredzi - zvakanaka, izvo zvingave mhedzisiro ine njodzi ;-)
Mujenari irori, havasi vatore mifananidzo asi vapepeti vari kuvatsiura nekutora mifananidzo ne iPhone nekuti mutori wemifananidzo akarasa jenari. Ini ndoziva vakati wandei vakatenga makamera eSLR anodhura uye mafoto avo akati wandei makirasi akashata kupfuura ayo anotorwa ne iPhone.
Ndichiri kumira nezvangu, kuti kuenzanisa hakuna musoro uye ndinongoomerera kune zvakanyanyisa. Chirevo chakanaka pakadai: Anoda kurova imbwa anogara achiwana tsvimbo.
Iyo lens yandinoshandisa ndeyemitambo yekupfura, apo mutori wemifananidzo anomira kubva kure uye mamiriro ekuvhenekesa haana kunaka -> IP iri mumaoko enyanzvi VS Nikon D600 mumaoko eamateur nekupfura kwakatevedzana.
Musiyano? Abyssal vachifarira maamateur. Hul inogona kuwanikwa nguva dzose ;-)
Saka hongu, zviri zvishoma pamusoro, asi kwete zvakanyanya. Ndakasangana nevanhu vazhinji vane midziyo yemifananidzo ye100000 uye kupfuura, asi pasina ruzivo rudiki. Hongu, hapana akawanda acho (kana ndisingaverenge vashanyi veJapan), asi ivo varipo.
Zvikasadaro, mutori wemifananidzo haakwanise kupfura zvinhu zvakawanda neSLR kamera isina studio light kana ... zivai kuti mafoto akawanda ane stylized ekunze anogona kuitwa ne iPhone uye semhedzisiro inogona kusaonekwa ... Hongu. , nyanzvi haigoni kutora basa rakabhadharwa nefoni (kana isina kubhadharwa nemugadziri wefoni), asi kazhinji zvinogoneka uye vazhinji vevatori vemifananidzo munguva yavo yekusununguka vanoratidza kuti zvinogoneka :)
asi zviri pamusoro pekuti zvinotevera zvinoshanda: "yakanakisa kamera ndiyo yandinayo" - SLR kamera kumba inobatsira zvikuru kwandiri ... uye ndine foni yangu neni nguva dzese : )
Zvinoshamisa kunzwa mazwi aya, semuenzaniso, kubva kumutori wemifananidzo uyo, mumafainari, anoda kutenga Canon 5D Mark III panzvimbo yaMark II, yaaive nayo pakutanga.
Demagoguery to the nth :-) Pano zvakare mumwe munhu ari kuedza kutiudza kuti mapikicha e-iPhone akaenzana nemifananidzo kubva pakhamera yemufananidzo. iyo mbozhanhare haizombofi iine optics, dhayamita yelens uye saizi yechip sezvakaita kamera. NEVER.
Uye kubva kune imwe-chinangwa application kune yakasarudzwa mhando yekukurumidza kuita, kugadzirisa paPC kunoenzana. Mutsara unonyanya kundishungurudza ndiwo mutsara uyu: "Migumisiro inowanzofanana zvikuru." LOL, saka kana une basa rakawanda mumaoko ako uye musoro, kugadzirisa pakombiyuta hakuzozvichengete, ichokwadi. uye kunyange yakanakisa-inotonhorera vintage mhedzisiro kubva kune imwe benzi app haizoichengetedze. richangove foto. i.e. app yakaita seKamera + haizombofananidzwe neAperture kana Photoshop Simply.
Just. Haisi mutambi mumwe chete, haina kana ligi imwechete. Uyu mutambo wakasiyana zvachose! Chinhu chimwe chete chandinoziva ndechekuti kupfura kwepikicha yakavanzika, kwandingadzingwa nekamera yeSLR, handikwanise kuenda nayo kumhenderekedzo yegungwa, nezvimwewo, kana kungoita emergency yandinoda kukurumidza kugovera pa web. yekupedzisira albhamu, asi ini ndichaida kubva kune SLR kamera, ini handisi kuzotaura nezvazvo.
Haubvumidzwe here pamhenderekedzo yegungwa uine SLR kamera? Ndinofanira kunge ndave ndiri munyika kwemakore mashoma ndisati ndasangana nerambidzo iyi. Kwandiri, mufananidzo wekukurumidzira ndeuyu -> kutora mufananidzo wegonhi remotokari rakaputsika, hongu, iP yakashanda zvakanaka nekuda kwechinangwa ichi.
Ehe. Uye 640 KB yendangariro inofanira kukwana kumunhu wese... ;-)
Iyo iPhone 5 uye kazhinji nharembozha dzine hunhu dzinogona kunyatso kubata zvinhu zvakafanana mumaoko eamateur seakajairwa compacts. Mushandisi akajairika kazhinji haapfure muRAW, haatambe neaperture uye kudzika kwemunda, uye kugadzirisa uye ruzha mazinga anowanzo kukwana kune izvo zvinodiwa nemushandisi (kugovera paFB, maemail mashoma, kumwe kuratidzwa kwewebhu, zvimwe. diki-fomati mufananidzo). Saka, kunyangwe zvakanaka kuita bonhora pamusoro pemhando yeSLR, chokwadi ndechekuti kune "kushandiswa kumba nemushandisi wenguva dzose" nhare inotora mafoto akanaka ndiyo imwe nzira yakakwana. Muchokwadi, hunhu hwezvinobuda mumafoni anhasi huri nani (kana ndikafuratira kudzika kwemunda) pane, semuenzaniso, kubva kumakamera emafirimu ehunyanzvi panguva iyo Leica akavaita mukurumbira, uye kunyangwe isu tichiri kuyemura mafoto. kubva kumichina iyoyo. Ndinotaura izvi ndine mutoro uzere uye semunhu anotora mifananidzo navo.
Nekamera hombe, munhu anowana mhando yemufananidzo, asi anozvipira zvakanyanya kukosha paramita kune vanhu vazhinji - kugadzirira, kuwanikwa uye nyore kushandisa. Uye sarudzo haisi pakati pekuva nemhando yepamusoro pikicha uye pikicha yemhando shoma yehunyanzvi, asi pakati pekuva nemufananidzo kana kusatora mufananidzo zvachose.
Kunyange zvazvo ndine maHasselblads uye mamwe mafomati epakati pamba, Leicas, MarkIIs ane boka reL lenses, ndinotora mifananidzo yakawanda ne iPhone nokuti iri pedyo pandinoida ... nguva dzose ... kwete nguva chete. Ini ndinofunga pachine nguva kuti ndichatora mifananidzo ZVINO. Hunhu hwemufananidzo ingori nyaya yehunyanzvi hwemifananidzo uye kudzidzira kushoma.
Yes you are right. ndima mbiri idzi dzine kapfungwa kangu kekutanga. te kutevedzera uye kugadzirira. uye hongu, virtuoso inogona kuridza kunyange chiridzwa chakaipa. Hapana mubvunzo nezvazvo.
Iwe unonyora nezve hunyanzvi hunosanganisira mhando yemifananidzo uye ipapo iwe une Mark II, iyo inopesana zvachose.
Iwe unogona kunge uri allergic kune zvinyorwa zvakafanana.
> "Pano zvakare mumwe munhu ari kuedza kutiudza kuti iPhone mapikicha akaenzana mapikicha kubva photo kamera".
Ndakaverenga chinyorwa chacho chose uye hapana chakabuda. Sekuona kwangu, munyori akapfupikisa chaizvo zvinogona kuitwa nenharembozha uye ndezvipi zvakanakira nekuipira.
Ini ndinofunga munhu wese anonzwisisa achanzwisisa kuti nharembozha haigone kuenzaniswa neDSLR. Asi nharembozha dzemazuva ano dzakatove dzakanaka zvakakwana kutora mufananidzo wakanaka navo - zvekushandisa zvisiri izvo kumba, panzendo ... Uye ndinobvumirana zvachose nemafungiro ekuti mufananidzo wakanaka unonyanya kutorwa nemufananidzo.
iyo yakanakisa kamera inogara iriyo yauinayo kana iwe uchida kutora mufananidzo... kazhinji haisi dslr;o)
Chinhu chinonyanya kukosha chehunyanzvi hwemhando yepikicha saizi yemuviri chip pamwe nemhando ye optics. Huwandu hwemapixels hunofanirwa kuenzana nehukuru hwemuviri hwechip.
