Kwiminyaka embalwa edlulileyo iikhamera zedijithali zazingaphezulu kunezixhobo zexabiso kwiigeeks. Iimodeli ngokwazo zazinkulu kwaye kunzima ukuzisebenzisa, kwaye ushicilelo olwenziwe ekhaya lwaludla ngokubhabha — lwalungenakufane lufanele utyalomali lwama- $ 800. Ukanti ukufota ngedijithali kunezibonelelo zako: unokujonga imifanekiso emva kwemizuzwana emva kokuyicoca, ucime ezimbi, uhlele abagcini, kwaye ungaze ufune ukuthenga umqulu wefilimu. Ukukhawulezisa phambili ukuza kuthi ga ngoku: itekhnoloji ephuculweyo kunye namaxabiso asezantsi athetha ukuba nkqu neLuddites ezifa nzima ziyayilahla indawo yazo ye-35 mm kunye nehlumelo. Kodwa ngokubulawa kweekhamera ukukhetha kuzo, uqala phi? Funda kuqala ngeyona nto ibaluleke kakhulu yokuya kwidijithali.
IMIQATHANGO
Isitshixo sokucaca kwemifanekiso yedijithali linani lee-megapixels-amachaphaza e-elektroniki enza umfanekiso wedijithali-ikhamera inokubamba. Eyona megapixels, isisombululo sibhetele. Njengoko uphakamisa isikali se-megapixel (iimodeli zabathengi ezikhoyo ngoku ukusuka kwenye ukuya kwezine), uya kufumana amandla okufumana isithuba somfanekiso kwaye uwandise ngaphandle kokuthotywa komgangatho womfanekiso. Ikhamera enee-megapixel ezimbini inokuvelisa ii-4-by-6 ezaneleyo, kodwa uPaul Worthington, ongumhlalutyi kwinkampani ye-future Image yokucebisa nge-digital-imaging, ucebisa abathengi ukuba bathenge imodeli ephezulu kakhulu, ene-megapixel ezintathu, ehambisa i-8-by -10 eziprintiweyo ezingaziwayo kwezo zithathwe ngekhamera esekwe kwifilimu. Sukuchitha imali yakho kwiimodeli ezingama- $ 2,000 ze-megapixel eziqala ukungena kwintengiso, nangona kunjalo. 'Ii-megapixels ezintathu zinika umgangatho wemifanekiso ngakumbi kunaye nabani na oya kuyidinga,' utshilo uWorthington.
IIMBONAKALO KUNYE NEZOKHUSELEKO
Njengazo zonke izixhobo ze-elektroniki, iikhamera zedijithali ezibiza kakhulu kwimarike zihlala ziza nezinto ezongezelelweyo kunye nezinto ezikumgangatho ophezulu. Yintoni oyifunayo ngenene? Okokuqala, qiniseka ukuba ukhetha imodeli enokusondeza okubonakalayo kunokujonga kwedijithali; endaweni yokukusondeza, le yokugqibela ivelisa nje izityalo kwaye ivuthela imifanekiso, ukunciphisa umgangatho wokuprinta. Kwaye ujonge into ebizwa ngokuba 'sisisombululo esidityanisiweyo,' indlela yokuphucula isisombululo esingabalulekanga kunesisombululo sekhamera kunye nesona siphelo-elona nani liphezulu lee-megapixels elinokubamba.
Ngazo zonke iintsimbi zobuchwephesha kunye neempempe zeekhamera zedijithali, kulula ukuba ulibale ukuba umgangatho weelensi unokuchaphazela ngokubukhali iifoto zakho. Ixabiso sisalathiso esisiseko esinye, ngokukaMichelle Lampmann, umhlalutyi wemifanekiso yedijithali kwi-InfoTrends Research Group eseBoston. Iikhamera ezinexabiso elingaphezulu kwe- $ 400 ziya kuba neglasi ecokisekileyo ngakumbi kunye nokukhanya okungcono, utshilo. Nangona bonke abenzi beekhamera beqhubeka nokuphucula iilensi zabo, uLampmann uphawula ukuba abavelisi abanjengoCanon, uNikon no-Olmpus ngokubanzi babonwa njengabona balungileyo.
Xa kuziwa kwiilensi, khumbula ukuba ubungakanani bubalulekile. Ngeekhamera zedijithali ezinobungakanani besundu, njengeCanon & Elos S300, into oyifumanayo ekuphatheni uyincama isebenze-iilensi zayo ezincinci azinakho ukuthatha i-palazzo yonke yase-Itali.
ISIKHUMBUZO
Icala elisezantsi ukuya kwisisombululo esiphakamileyo seekhamera kukuba imifanekiso ithatha indawo engaphezulu kwiimemori khadi ezizigcina kwikhamera yakho. Uninzi lweekhamera ziza nekhadi elinye le-16 MB, eligcina kuphela imifanekiso ekumgangatho ophezulu emihlanu, ke wena & ampos; Kuya kufuneka uthenge i-32 MB okanye i-64 MB khadi ($ 50- $ 60 kunye ne- $ 89- $ 100, ngokwahlukeneyo).
Uninzi lweemodeli zisebenzisa imemori khadi yeCompact Flash okanye enye eyenziwe yiSmartMedia. Ukuba u & apos uhlobo oluya kuthatha imifanekiso emininzi, yiya nekhamera esebenzisa eyangaphambili. Amakhadi e-compact e-compact ayaphuhliswa ngokukhawuleza kancinci kunee-SmartMedia, ke unokulindela ukuba ube nexabiso eliphantsi, ukhetho olunamandla aphezulu ngokukhawuleza. Ukuba ikhamera inememori eyahlukileyo, jonga ngononophelo ngaphambi kokuthenga. I-Sony & apos; s Memory Stick iyahambelana kuphela ne-Sony kunye neapos yomnini weCyberShot, kwaye zimbini kuphela izinto ezinokukhethwa ngabashicileli: uSony okanye uEpson. I-Agfa & apos; s ePhoto CL30 Clik! Ikhamera igcina imifanekiso kwiidiski ze-Iomega PocketZip, ii-intshi ezimbini ze-CD kunye neeapos ezithengisa malunga ne- $ 10, kodwa abanazo & ampos; ababambanga nabanye abavelisi kwaye umngcipheko uphelelwe lixesha.
Ukwenza imemori ibe nkulu, uninzi lweekhamera zikuvumela ukuba utshintshe isisombululo (inani lee-megapixels ezisetyenziselwa ukufaka umfanekiso) kunye nefomathi yoxinzelelo (indlela ogcinwa ngayo kwaye wenziwe kwakhona xa ulayishwe kwikhompyuter yakho) ngaphambi kokuba udubule. Isisombululo esisezantsi kunye noxinzelelo oluphezulu nganye inyusa amandla ememori. Ngokwe-InfoTrends & apos; Lampmann, eyona ndlela yokupakisha iifoto ezininzi kwikhamera yakho kukunyusa uxinzelelo endaweni yokunciphisa isisombululo, kuba isisombululo sichaphazela ngqo umgangatho womfanekiso. Kwaye xa uqala ukunciphisa isisombululo kunye nokonyusa uxinzelelo lokuba ufumane umfanekiso osemgangathweni osezantsi, utshilo. Kwaye ukutshintsha inxenye enye ye-equation kuyasebenza: imemori khadi eyi-32 MB enokubamba imifanekiso eyi-12-megapixel kathathu kuxinzelelo olusezantsi, umzekelo, inokugcina imifanekiso engama-40 ngokucinezelwa okwandileyo.
AMANDLA
Qiniseka ukuba uthenga iiseti ezimbalwa zeebhetri eziphinda zitshajwe zekhamera yakho (ihlala ilingana ne- $ 12 ezine), ke wena & amp; uya kuhlala unezongezelelo xa uphelelwa yincindi. Nangona iiyure ezimbalwa zokusebenzisa kwikhamera yedijithali zanele ukukhupha iibhetri, uninzi lwabavelisi abazithengisi iimodeli zabo ngezinto ezinokuphinda zisebenze. 'Xa ndisiya phesheya into endiyithengayo ndihlala ndiyisebenzisa kwakhona,' utshilo uWorthington. Icebo lakhe lokwenza ukuba usuku lonke lube neeseti ezimbini zeebhetri? Cima isikrini seLCD esikwenza ukuba uphinde ujonge imifanekiso yakho. (Oko kukwathetha ukuba akufuneki uthenge ikhamera ngaphandle kwesikhangeli, kuba inyanzela ukuba usebenzise iLCD ukuseta iifoto.)
KUYashicilelwa
Zonke iikhamera ziza nesoftware enokusetyenziselwa ukuphucula imifanekiso kwikhompyuter yakho. Ke ngomshicileli kunye nephepha lomgangatho wefoto, unokuvelisa eyakho imifanekiso ekhaya. Iiprinta ze-ink-jet zezona zibiza ixabiso eliphantsi, kodwa wena & amp; d wenza kakuhle ukutyala imali kwimodeli entsha esebenzisa itekhnoloji enganyangekiyo, ezinye zazo zikwenza ukuba ulungelelanise imemori khadi ngqo kumshicileli. Kunconywe i-Sony DPP-SV55 ($ 350), iOlimpus Camedia P-200 ($ 450), kunye neCanon & apos; s CP-10 ($ 399), imodeli ehambelana nekhadi lokuthenga ngetyala. Ukuba awufuni ukwenza iiprinta zakho, iilebhu ezininzi zeefoto zinokuwenza umsebenzi, okanye ujonge kwi-intanethi. IShutterfly.com ikuvumela ukuba ulayishe iifoto kwiWebhusayithi yayo yasimahla (ungagcina imifanekiso enesisombululo esiphakamileyo njengoko uthanda & apos) kwaye emva koko uodole imifanekiso (ukusuka kwiisenti ezingama-49 nge-4-by-6 yoshicilelo).
