LOG Gamma curve - S-log, C-Log, V-log ndi zina zambiri…
Ngati mungajambule kanema simudzakwanitsa kulemba zonse. Kuphatikiza pa kupsinjika kwazithunzi za digito, mumatayanso gawo lalikulu la sipekitiramu kuchokera ku kuwala komwe kulipo.
Izi sizikuwoneka bwino nthawi zonse, mumaziwona makamaka pamikhalidwe yomwe ili ndi kusiyana kwakukulu pakuwunikira. Kenako kujambula ndi mbiri ya LOG Gamma kungapereke yankho.
Kodi LOG Gamma ndi chiyani?
Mawu akuti LOG amachokera ku logarithmic curve. Pakuwombera wamba, 100% ingakhale yoyera, 0% ingakhale yakuda ndi imvi ingakhale 50%. Ndi LOG, yoyera ndi 85% imvi, imvi ndi 63% ndipo wakuda ndi 22% imvi.
Zotsatira zake, mumapeza chithunzi chosiyana kwambiri, ngati kuti mukuyang'ana kupyola chifunga chowala.
Sikuwoneka wokongola ngati chojambulira chosaphika, koma curve ya logarithmic imakulolani kuti mujambule zambiri zamasewera a gamma.
Kodi LOG mumagwiritsa ntchito chiyani?
Ngati mungasinthe kuchokera pa kamera mpaka kumapeto, kujambula mu LOG sikuthandiza. Mumapeza chithunzi chozimiririka chomwe palibe amene angakonde.
Kumbali ina, zowombera mumtundu wa LOG ndizoyenera kuwongolera bwino pakuwongolera utoto komanso zili ndi tsatanetsatane wambiri pakuwala.
Chifukwa muli ndi zambiri zosinthika zomwe muli nazo, mudzataya zambiri pakukonza mitundu. Kujambula ndi mbiri ya LOG kumakhala kopindulitsa ngati chithunzicho chili ndi kusiyana kwakukulu komanso kuwala.
Kuti tipereke chitsanzo: Ndi mawonekedwe owoneka bwino a studio kapena chroma-key ndikwabwino kujambula ndi mbiri yokhazikika kuposa mbiri ya S-Log2/S-Log3.
Kodi mumalemba bwanji mu LOG?
Opanga angapo amakupatsani mwayi wojambula mu LOG pamitundu ingapo (yapamwamba).
Kuyamba ndi zolemba zanu zoyimitsa nkhani
Lembetsani ku kalata yathu yamakalata ndikutsitsa kwaulere ndi zolemba zitatu. Yambani ndikupangitsa nkhani zanu kukhala zamoyo!
Tidzangogwiritsa ntchito imelo yanu kutsamba lathu ndikulemekeza lanu zachinsinsi
Si kamera iliyonse yomwe imagwiritsa ntchito LOG zomwezo. Sony imayitcha S-Log, Panasonic imayitcha V-Log, Canon imayitcha C-Log, ARRI ilinso ndi mbiri yake.
Kuti ndikuthandizeni, pali ma LUT angapo okhala ndi mbiri zamakamera osiyanasiyana omwe amapangitsa kusintha ndikusintha mtundu kukhala kosavuta. Dziwani kuti kuwonetsa mbiri ya Log kumagwira ntchito mosiyana ndi mbiri yokhazikika (REC-709).
Ndi S-Log, mwachitsanzo, mutha kuwonetsa maimidwe a 1-2 kuti mupeze chithunzi chabwinoko (phokoso lochepa) pambuyo pake popanga.
Njira yolondola yowonetsera mbiri ya LOG imadalira mtundu, chidziwitsochi chikhoza kupezeka patsamba la wopanga makamera.
Ngati mukufuna kupindula kwambiri ndi zojambulira zanu, kujambula mumtundu wa LOG ndiye chisankho chabwino kwambiri. Muyenera kukonzekera kukonza chithunzicho pambuyo pake, zomwe mwachiwonekere zimatenga nthawi.
Itha kukhala ndi mtengo wowonjezera (wachidule) filimu, kopanira kanema kapena malonda. Ndi chojambulira cha studio kapena lipoti lankhani zingakhale bwino kuzisiya ndikujambula mu mbiri yokhazikika.
Moni, ndine Kim, mayi komanso wokonda kuyimitsa zoyenda komanso wodziwa zambiri pakupanga media komanso kakulidwe ka intaneti. Ndili ndi chikhumbo chachikulu chojambula ndi makanema ojambula, ndipo tsopano ndikudumphira molunjika kudziko loyimitsa. Ndi blog yanga, ndikugawana zomwe ndaphunzira ndi inu anyamata.
