LOG Gamma curves - S-log, C-Log, V-log da ƙari…
Idan kun yi rikodin bidiyo ba za ku taɓa iya yin rikodin duk bayanan ba. Baya ga matsar hoton dijital, kuna kuma rasa babban ɓangaren bakan daga cikin samuwa haske.
Wannan ba koyaushe ba ne a bayyane, kuna ganin shi musamman a cikin yanayi tare da babban bambanci a cikin hasken wuta. Sannan yin fim tare da bayanan LOG Gamma na iya ba da mafita.
Menene LOG Gamma?
Kalmar LOG ta fito ne daga lanƙwan logarithmic. A cikin harbi na al'ada, 100% zai zama fari, 0% zai zama baki kuma launin toka zai zama 50%. Tare da LOG, fari shine 85% launin toka, launin toka shine 63% kuma baki shine 22% launin toka.
A sakamakon haka, kuna samun hoto tare da ɗan bambanci, kamar kuna kallo ta cikin haske mai haske na hazo.
Ba ya yi kama da kyan gani a matsayin ɗan rikodin rikodi, amma lanƙwan logarithmic yana ba ku damar yin rikodin mafi yawan bakan gamma.
Me kuke amfani da LOG?
Idan ka gyara kai tsaye daga kyamara zuwa sakamako na ƙarshe, yin fim a LOG ba shi da wani amfani. Kuna samun hoton da ba wanda zai so.
A gefe guda, harbin kayan abu a cikin tsarin LOG yana da kyau don daidaitawa mai kyau a cikin tsarin gyaran launi kuma yana da cikakkun bayanai a cikin haske.
Saboda kuna da kewayo mai ƙarfi da yawa a hannunku, zaku rasa ƙarancin daki-daki yayin gyaran launi. Yin fim tare da bayanin martaba na LOG yana da daraja kawai idan hoton yana da babban bambanci da haske.
Don ba da misali: Tare da daidaitaccen wurin da aka fallasa ɗakin studio ko maɓalli na chroma yana da kyau a yi fim tare da madaidaicin bayanin martaba fiye da bayanin martabar S-Log2/S-Log3.
Ta yaya kuke yin rikodi a LOG?
Yawancin masana'antun suna ba ku zaɓi don yin fim a cikin LOG akan nau'ikan nau'ikan (high-end).

Ba kowane kamara ke amfani da ƙimar LOG iri ɗaya ba. Sony ya kira shi S-Log, Panasonic ya kira shi V-Log, Canon ya kira shi C-Log, ARRI kuma yana da nasa bayanin martaba.
Don taimaka muku, akwai LUT da yawa tare da bayanan martaba don kyamarori daban-daban waɗanda ke sauƙaƙe gyara da gyaran launi. Lura cewa fallasa bayanin martabar Log yana aiki daban fiye da daidaitaccen bayanin martaba (REC-709).
Tare da S-Log, alal misali, zaku iya wuce gona da iri na tsayawa 1-2 don samun hoto mafi kyau (ƙasa amo) daga baya a cikin samarwa.
Hanya madaidaiciya don fallasa bayanin martabar LOG ya dogara da alamar, ana iya samun wannan bayanin akan gidan yanar gizon masana'anta kamara.

Idan kuna son samun mafi kyawun rikodi, yin fim a tsarin LOG shine mafi kyawun zaɓi. Dole ne ku kasance cikin shiri don gyara hoton bayan haka, wanda a fili yana ɗaukar lokaci.
Tabbas yana iya ƙara ƙimar fim (gajeren) fim, shirin bidiyo ko kasuwanci. Tare da rikodin studio ko rahoton labarai yana iya zama mafi kyau a bar shi a yi fim a daidaitaccen bayanin martaba.
