Understanding Resolution muMifananidzo
Iyi dzidziso ndiyo yechipiri mune yakawanda-chikamu chakateedzana chakafukidza Aspect ratios, Chisarudzo, uye Kurimwa vs. Resizing.
Kugadziriswa ndechimwe chezvinhu zvisina-intuitive izvo vese vatori vemadhijitari vanofanirwa kuziva pakupedzisira. Sei? Nekuti resolution ine mhedzisiro yakanangana nehunhu hwemapikicha ako akadhindwa.
Kugadziriswa ndiyo nhamba yemapikisheni mufananidzo wedhijitari une. Iyi nhamba inoyerwa mumamegapixels. Kana iwe ukatenga 17 megapixel kamera, izvi zvinoreva kuti chemhando yepamusoro mufananidzo iyo kamera inogona kuburitsa ichave ne17 mamirioni pixels. Funga nezve 4 × 6 iine 17 mamirioni pixels - iwo mapikisheni anozove ari madiki zvekuti iwe haugone kuaona, uye pikicha yako ichataridzika kunge yakasikwa uye ichokwadi.
Iti, zvisinei kuti iyo imwechete 4 × 6 chete ine mapikiseli zana. Govanisa iwo mufananidzo kumusoro mumabhokisi zana, uye zadza bhokisi rega rega neruvara. Mufananidzo wako unoita senge boka remakwere uye unotakura zvishoma kufanana nechinhu chako. Izvi ndizvo zvatinodaidza kuti pixelated mufananidzo.
Kana tichitaura nezvemifananidzo yakadhindwa, tinokurukura chisarudzo maererano nemadhora pamasendimita (kana DPI). DPI inoreva iyo nhamba yemavara mavara iyo purinda yako inoisa mune yega yega inch yemufananidzo wako.
Patinenge tichitaura nezvemifananidzo pa internet, macomputer skrini, maTV, nezvimwe, tinokurukura resolution maererano nemapikisheni padiki (kana PPI).
Kune mibvunzo yakati wandei yakakosha kwatiri sevateereri vemadhijitari.
Kutanga, ndingaite sei kukura kuita mufananidzo wangu isati yave pixel-y ichitarisa? Mune mamwe mazwi, faira rangu redhijitari rine mapikisheni akakwana anokwanisa kutambanudza mufananidzo mukuru asi usingaonekwe neziso? Iyo hombe kudhinda saizi yemufananidzo wako inogumira nenhamba yemapikisheni kamera yako yakaiswa mairi. (Zvino, kune nzira dzekuwedzera mapikisheni matsva mu Photoshop kuitira kuti iwe ugone kuwedzera mufananidzo wako zvakanyanya, asi ndiyo hurukuro yekuti mumwe munhu atungamire!)
Ngatidzokerei kumuenzaniso weiyo 4 × 6. Iti uyu mufananidzo wakaita pixels mazana maviri nemazana mana. 2400 yakakamurwa ne2400 inches = 6 pixels pa inch. Izvo zvinopfuura zvakakwana kuti ugadzire mhando yekudhinda.
Nekudaro, taura isu taida kuwedzera iyo 4 × 6 kusvika 40 x 60. Iye zvino tinofanirwa kupatsanura mapikiseti mazana maviri nemazana mana nemasendimita makumi matanhatu, zvichitipa mapikisheni makumi mana padiki. Icho hachisi kuzove chinyorwa chakanaka.
Kusvika pane yakakwana DPI yekudhinda kwakanaka, zvinoenderana neprinta. Photo labs kana yako yekumba purinda inofanirwa kuve nemazano iwe Pandinodhinda, ini ndinovavarira kushoma resolution ye 240 DPI.
Mubvunzo wechipiri wevateereri vemadhijitari ndewekuti, "Ndeapi masikirwo akakwana ekuratidza mifananidzo yangu paindaneti kana kutumira maemail?" Iyo yakanyanya PPI iyo iyo monitors, maTV, uye zvimwe zvikwangwani zvinogona kuratidza ndizvo 72 PPI. Kana mufananidzo wako uine PPI yakakura kudarika makumi manomwe nemaviri, iwo mamwe mapikisheni anonyanya kutambiswa nzvimbo. Iyi inyaya nekuti vari kuenda kunonoka kurodha pasi kwako uye kurodha nguva painternet, uye tora yakakosha hard drive nzvimbo.
Nehunyanzvi, mufananidzo unounzwa kubva kamera hauna DPI / kana PPI marongero. Asi software yedu yekuunza kunze kwenyika inowanzo tipa imwe, uye dzimwe nguva makamera anoronga nhamba yekugadzirisa mu data reEXIF yemufananidzo. Kuti uwane kupurinda kwakanaka, ungangoda kushandura iyi resolution yemufananidzo wako weSOOC, kana iwe ungasadaro.
Kuti utarise resolution yazvino / PPI yemufananidzo wako, nyora control + alt + i (raira + opt + i paMac) mune chero Photoshop kana Photoshop Elements. Ndiyo sarudzo + yekuraira + ini paMacs.
Ziva kuti resolution yacho ndeye 72 PPI chete, asi hupamhi i24 inches. Dai ndaizoipurinda izvozvi, sediki diki, taura 4 × 6 tinenge tagona. Kana ini ndikaedza kuipurinda se24 × 36 ine mapikiseli makumi manomwe nemaviri pa inchi, inenge iri pixelated kwazvo. Kuwedzera chisarudzo:
- Ita shuwa kuti Constrain Proportions iripo
- Bvisa Muenzaniso Wemufananidzo
- Chinja resolution yacho kune yako yakanaka yekudhinda marongero
Iye zvino unogona kuona kuti hupamhi hwemufananidzo hwachinja kuita 7.2 inches upamhi. Ziva kuti iwo mapikisheni mapikicha haana kuchinja - hatina kuwedzera kana kubvisa mapikisheni nekuti Muenzaniso Wemufananidzo wakadzimwa.
Ndakakura sei kuprinta uyu mufananidzo? Zvinoenderana nesarudzo shoma yemudhindiri uye kuti ndinovimba Photoshop ku “Ratidza” chifananidzo nekugadzira mapikisheni matsva uye kuyedza kufungidzira kuti anofanirwa kutaridzika sei. . Bvunza yako labhu yemifananidzo kana uchidhinda mikuru kudhindisa kuve nechokwadi uine ruzivo rwakakwana.
