Daim duab Archiving Format Guide
Cov lus qhia dav dav los pab koj nkag siab cov duab archiving hom ntawv qhia.
Nkag siab cov duab Archive
Cov duab archiving suav nrog xaiv cov ntaub ntawv tawm tswv yim uas sib npaug ntawm cov duab zoo, khaws cia kom zoo, thiab siv tau mus ntev. Tsis zoo li cov qauv tsim kho rau lub vev xaib lossis kev sib koom tam sim ntawd, cov ntaub ntawv khaws cia tseem ceeb ua ntej khaws cov ntaub ntawv thiab kev sib raug zoo yav tom ntej. Qhov kev xaiv ntawm hom cuam tshuam zoo npaum li cas koj cov duab yuav muaj sia nyob cov kev hloov pauv thev naus laus zis ntau xyoo. Lossless hom zoo li TIFF thiab PNG khaws txhua pixel ntawm cov ntaub ntawv qub, ua rau lawv zoo tagnrho rau cov ntawv luam ntawm cov duab tseem ceeb. Cov qauv no xyuas kom meej tias tsis muaj duab zoo raug txi thaum lub sijhawm khaws cia, txawm tias lawv xav tau ntau qhov chaw cia. Lossy hom ntawv zoo li JPEG tuaj yeem tsim nyog rau qee lub hom phiaj archival thaum qhov chaw cia tsuas yog txwv, tab sis lawv yuav muab cov ntaub ntawv pov tseg tas li thaum compression. Cov tswv yim archival niaj hnub no feem ntau siv ntau hom kev mus kom ze, tswj cov ntaub ntawv zoo zoo thaum tsim cov ntawv luam tawm rau txhua hnub. Txoj kev hybrid no sib npaug kev khaws cia xav tau nrog cov tswv yim cia txwv, kom ntseeg tau tias siv tau tam sim ntawd thiab kev txuag mus sij hawm ntev ntawm koj cov duab nco.
TIFF: Tus Qauv Kub rau Duab Archives
Tagged Image File Format (TIFF) sawv cev rau cov qauv siv dav tshaj plaws rau kev yees duab khaws cia hauv cov chaw tshaj lij thiab chaw haujlwm. TIFF cov ntaub ntawv txhawb nqa ob qho tib si compressed thiab uncompressed cia, nrog lossless compression xaiv uas txo cov ntaub ntawv loj yam tsis tau txi cov duab zoo. Cov hom ntawv haum rau ntau yam xim tob, los ntawm 8-ntsis txog 32-ntsis ib channel, ua rau nws haum rau txhua yam los ntawm cov duab yooj yim mus rau high-dynamic-ntau cov duab tshaj lij. TIFF qhov kev txhawb nqa metadata dav dav tso cai rau embedded cia ntawm lub koob yees duab teeb tsa, cov ntaub ntawv pov thawj, cov ntsiab lus tseem ceeb, thiab cov lus piav qhia ntxaws. Qhov peev xwm metadata no ua pov thawj tsis muaj nuj nqis rau kev teeb tsa cov duab loj loj thiab khaws cov ntaub ntawv pov thawj dhau sijhawm. Cov hom ntawv kuj txhawb ntau cov khaubncaws sab nraud povtseg thiab pob tshab, ua rau nws tau tshaj cov duab editing workflows. Lub ntsiab drawback ntawm TIFF nyob rau hauv nws cov ntaub ntawv loj loj, tshwj xeeb tshaj yog rau cov duab daws teeb meem. Ib daim duab 24-megapixel tuaj yeem yooj yim tshaj 100MB thaum khaws cia ua ib qho TIFF tsis txaus siab. Txawm li cas los xij, cov nqi khaws cia niaj hnub no tau ua rau qhov txwv tsis pub tsawg, thiab cov qauv kev sib raug zoo thoob ntiaj teb thoob plaws cov platforms thiab cov ntawv thov software ua pov thawj qhov peev txheej khaws cia rau lub hom phiaj tseem ceeb archival.
JPEG: Sib npaug zoo thiab khaws cia zoo
Txawm hais tias yog hom ntawv poob, JPEG tseem cuam tshuam rau kev khaws cov duab thaum siv judiciously. Niaj hnub nimno JPEG encoding ntawm qib zoo ntawm 90% lossis siab dua ua rau pom qhov tsis pom qhov txawv ntawm qhov tseem ceeb thaum ua tiav cov ntaub ntawv loj txo. Rau tsev neeg cov duab sau thiab khaws cia cov hom phiaj dav dav, JPEG zoo tuaj yeem muab qhov kev pom zoo ntawm cov duab zoo thiab kev cia khoom. JPEG’s universal compatibility ua kom ntseeg tau tias cov duab archived tseem siv tau thoob plaws txhua lub cuab yeej thiab lub platform, tam sim no thiab yav tom ntej. Daim ntawv thov dav dav muab kev ntseeg siab tias JPEG kev txhawb nqa yuav muaj nyob rau ntau xyoo tom ntej. Tsis tas li ntawd, JPEG cov ntaub ntawv feem ntau thauj khoom thiab tso saib sai dua li lawv cov neeg tsis muaj kev sib tw, txhim kho cov neeg siv kev paub thaum tshawb xyuas cov duab loj loj. Txawm li cas los xij, JPEG qhov tsis zoo ua rau nws tsis tsim nyog rau cov duab uas yuav xav tau kev kho lossis txhim kho yav tom ntej. Txhua lub sijhawm JPEG raug kho thiab khaws tseg, kev poob zoo ntxiv tshwm sim. Rau lub hom phiaj archival, xav txog JPEG feem ntau rau qhov kawg, cov duab ua tiav es tsis yog cov duab qub uas yuav xav tau kev hloov kho yav tom ntej.
PNG thiab Lwm Cov Kev Xaiv Lossless
Portable Network Graphics (PNG) muaj kev poob qis nrog cov ntaub ntawv me me dua li tsis muaj TIFF, ua rau nws zoo nkauj nruab nrab hauv av rau kev khaws duab. PNG ua tau zoo tshwj xeeb nrog cov duab uas muaj cov xim loj, cov ntawv sau, lossis cov duab kos duab. Cov hom ntawv txhawb cov pob tshab thiab muab kev zoo heev rau cov screenshots, cov ntaub ntawv digitized, thiab cov duab nrog cov npoo ntse lossis cov xim palettes. PNG qhov kev sib raug zoo hauv lub vev xaib ua kom muaj kev nkag mus tau ntev, txawm hais tias nws tsis muaj qee qhov ntawm TIFF cov yam ntxwv zoo li ntau qhov chaw xim thiab kev txhawb nqa metadata. Rau cov duab nrog cov suab nrov tsis tu ncua thiab gradients, PNG cov ntaub ntawv feem ntau xaus qhov loj dua li cov ntaub ntawv JPEG zoo sib xws thaum muab kev txhim kho qhov muag tsawg. Lwm yam kev tsis zoo uas tsim nyog xav txog suav nrog WebP (muab qhov zoo tshaj plaws compression rau PNG) thiab HEIF (muab qhov zoo tshaj plaws-rau-loj piv). Txawm li cas los xij, cov qauv tshiab no ntsib cov teeb meem kev sib raug zoo nrog cov software qub thiab cov tshuab. Thaum xaiv lwm hom ntawv, xav txog seb qhov kev khaws cia yuav ua rau muaj kev txhawj xeeb txog kev nkag mus tau rau yav tom ntej.
RAW Files: Khaws cov ntaub ntawv duab ntau tshaj plaws
RAW cov ntaub ntawv sawv cev rau qhov kawg archival hom, muaj cov ntaub ntawv tiav, tsis tau ua tiav los ntawm cov koob yees duab digital sensors. Tsis zoo li JPEG lossis txawm tias TIFF cov ntaub ntawv ua tiav los ntawm lub koob yees duab firmware, RAW cov ntaub ntawv khaws cia tag nrho cov dynamic ntau thiab cov ntaub ntawv xim ntes thaum raug. Cov ntaub ntawv khaws cia zoo no tso cai rau ntau xyoo tom qab kev ua haujlwm yooj yim lossis ntau xyoo tom qab thaij duab. Txhua lub tuam txhab lub koob yees duab siv cov tswv yim RAW (CR2 / CR3 rau Canon, NEF rau Nikon, ARW rau Sony), uas tuaj yeem tsim kev txhawj xeeb txog kev sib raug zoo mus ntev. Adobe’s open-source Digital Negative (DNG) hom hais txog qhov teeb meem no los ntawm kev muab tus qauv RAW hom ntawv uas ua kom muaj kev nkag mus rau yav tom ntej. Hloov cov ntaub ntawv RAW rau DNG tuaj yeem muab kev ruaj ntseg archival thaum tuav tag nrho cov duab qub. RAW cov ntaub ntawv feem ntau xav tau 20-50MB ib daim duab, ua rau cov nqi khaws cia tseem ceeb rau kev sau loj. Txawm li cas los xij, lub peev xwm los siv cov duab ua haujlwm yav tom ntej rau cov ntaub ntawv sensor qub feem ntau ua rau qhov kev nqis peev no. Xav txog RAW archiving tseem ceeb rau cov duab tsis tuaj yeem hloov tau lossis cov duab uas muaj keeb kwm tseem ceeb.
Cov tswv yim kev koom tes thiab cov kev coj ua zoo tshaj plaws
Cov duab archiving muaj txiaj ntsig txuas ntxiv dhau qhov kev xaiv hom kom suav nrog cov koom haum ua ke. Ua raws li cov ntaub ntawv teev npe cov lus pom zoo uas suav nrog hnub tim, cov ntsiab lus, thiab cov lej sib lawv liag kom ntseeg tau tias kev txheeb xyuas qhov laj thawj thiab rov qab tau yooj yim. Tsim cov txheej txheem hierarchical cov ntaub ntawv tsim los ntawm xyoo, kev tshwm sim, lossis cov ntsiab lus, tsis txhob muaj cov ntawv sau ntau dhau uas yuav ua rau tsis muaj sijhawm. Kev tswj hwm metadata ua pov thawj tseem ceeb rau kev siv sijhawm ntev archive. Embed cov ntsiab lus, cov lus piav qhia, cov ntaub ntawv qhov chaw, thiab cov ntaub ntawv ntiag tug ncaj qha rau hauv cov duab cov ntaub ntawv es tsis yog tso siab rau cov ntaub ntawv sab nraud uas yuav ua rau puas lossis ploj. Cov cuab yeej zoo li Adobe Bridge, Photo Mechanic, lossis txawm tias ua haujlwm hauv qhov system nta tuaj yeem ua kom cov ntaub ntawv nkag mus hla ntau cov duab ib txhij. Kev saib xyuas archive tsis tu ncua tiv thaiv cov ntaub ntawv poob thiab ua kom muaj kev nkag mus tau txuas ntxiv. Siv lub tswv yim thaub qab raws li txoj cai 3-2-1: khaws peb daim ntawv theej ntawm cov duab tseem ceeb, khaws cia rau ntawm ob hom xov xwm sib txawv, thiab khaws ib daim ntawv tawm ntawm qhov chaw. Kev txheeb xyuas qhov tseeb ntawm cov ntaub ntawv ib ntus, txav cov ntaub ntawv los ntawm cov ntaub ntawv khaws cia cov laus, thiab hloov kho cov qauv thaum tsim nyog los tswj kev sib raug zoo nrog cov qauv siv thev naus laus zis.
