Inendima ebalulekile ekwakheni ukuqonda okunethezeka kwesithombe nevidiyo ngokusebenzisa iphrojekithi idlala ngesikrini. Ukunquma kahle ukukhetha kwayo, udinga ukwazi konke ngezinhlobo, ubukhulu kanye nezinto zokwakha.
Ungakhetha kanjani isikrini esikwaziyo sokuphrinta kwi-tripod?
Ngakho-ke, sizokhetha isikrini ku-tripod yeprojekti, sincike ezinyathelweni ezilandelanayo. Futhi ekuqaleni kwabo kudingeka sithole isinqumo ngohlobo lweskrini esiyidingayo.
Uma uhlela ukusebenzisa isikrini kuphela ngaphakathi kwekamelo elilodwa, ungabuka ngesibindi emaskrini omqulu anamathele edwaleni nodonga. Kodwa uma udinga ukuhambisa izethulo ezindaweni ezihlukahlukene, udinga isikrini esikwazi ukuphathekayo kwi-tripod.
Mhlawumbe, ungase udinge isikrini ngokubuka okungafani, uma iphrojekitha itholakala ngemuva kwayo. Izikrini ezinjalo azicabangi kakhulu ekukhanyeni, ngaphandle kweprojekti kanye nayo yonke imishini izofihlwa kubabukeli futhi ngeke iphazamise nabo.
Isinyathelo sesibili ekukhetheni isikrini sephrojekithi sinquma isayizi edingekayo. Lesi sinyathelo sinomthwalo wemfanelo kakhulu, futhi lapha kubalulekile ukuqondiswa yimithetho enjalo:
- Isikrini akufanele sibe sikhulu kune-1/2 ebanga kubalandeli emgqeni wokuqala;
- Isikrini akufanele sibe ngaphezulu kwe-1/6 ebangeni kubakhangisi emgqeni wokugcina;
- Isikrini kufanele sibe okungenani 1/8 ebangeni ukusuka kubabukeli emgqeni wokugcina;
- Umngcele ophansi wesikrini akufanele uwe ngaphansi kwe-125 cm ukusuka phansi, ukuze bonke ababukeli bakwazi ukubona isithombe ngokuphelele.
Umzuzwana olandelayo ukhetha ifomethi yeskrini. Kuye ngephrojekthi, noma yisiphi isithombe sinesici esithile sokuphakama - ububanzi nobubanzi. Ngamafayili amaningi aphezulu anefomethi lesikwele, ifomethi yeskrini izoba nesilinganiso se-1: 1 sesici. Uma uneprojera ye-multimedia ebonisa ngefomethi yevidiyo, isilinganiso sesici seskrini kufanele sibe ngu-4: 3.
Kumaphrojekti we-slides ngefomethi ye-35 mm, isilinganiso sesici seskrini sizoba ngu-3: 2. Yebo, ngokubuka ama-movie ku-DVD nakwezinye amafomethi we-HDTV, isilinganiso se-screen kufanele sibe ngu-16: 9.
Ngokusobala, ukuthola umphumela omuhle udinga ukusebenzisa isikrini esifana nesakhiwo sesithombe. Njengesikrini somhlaba jikelele sinesakhiwo se-1: 1 no-4: 3. Isibonelo, ube neskrini sephrojekti ku-tripod esilinganisa i-200x200 cm, ungakwazi ukuvula umqulu endaweni ephakeme ngokulungisa ifomethi yeskrini kufomethi yesithombe.
Okokugcina, umgomo wokugcina obalulekile wokukhetha isibuko esibukwayo kwi-tripod yindwangu nokwaziswa kokugqoka kwesikrini seprojekti. Kuye ngokwazi kwezinto zokugqoka ukubonisa nokusabalalisa ukukhanya okungena kuwo, ukukhanya kwesithombe kuzohluka.
Ukukhethwa kwendwangu yesikrini kuncike ngenhloso yokusebenzisa kwayo. Kodwa noma kunjalo, udinga ukucabangela ukukhanya kwiprojekitha nendawo yayo, kanye nezimo zokukhanyisa ekamelweni nokucushwa kwayo.
Uma izinto zokumboza kwesikrini zikhethwa ngokungalungile, akubona bonke ababukeli bazokwazi ukubona isithombe esibonisiwe esikrinini. Inketho enkulu kunazozonke yesikrini esinomshini omhlophe obomvu okulingana nomklamo wokucubungula oseduze no-1. Kuzoveza nokuhlakaza
Muva nje, izikrini ezinezembatho ze "beaded" zivame kakhulu. Ngaphezulu kwawo kukhona ubuhlalu obukhulu obenziwe ngilazi, kubonisa ukukhanya kwesigameko ngaphakathi kwesikhala esincane. Isithombe esithunyelwe esikrinini esinjalo sibonakala siqhakazile futhi sihle, uma usibuka ngakwesokudla. Noma kunjalo, kubabukeli abaseceleni, isithombe sizoba mnandi kakhulu.
