In response to high demand in the film production market, a log video recording mode called V-Log L has been implemented for the Panasonic GH4. The release of the new gamma mode is imminent.
Leading up to the release of the $99 paid upgrade that can only be purchased through a reseller, the new firmware update 2.3 intended to introduce the upgrade functionality apparently has a bug that allows users to unlock V-Log L upfront and for free. (I won’t include a link to that workaround as I believe it is not right to acquire it that way). B&H give you a $100 discount on the Panasonic GH4 for another 3 days, so the upgrade won’t cost you anything during that time.
Note that trying the V-Log L workaround will also lead to zebras & highlights working incorrectly.
Concerning the use of V-Log, Panasonic ambassador and filmmaker Nick Driftwood did some testing. He shot this beautiful boat video below and told us: “V Log is very good when exposed correctly. Ive pushed ‘over exposure’ upto 1.5 stops and I know James Miller has had great results at +2″
Nick Driftwood says the V-Log L upgrade is a “must-buy”. And looking at our own experience with the Panasonic GH4 we can certainly only agree. The V-Log profile will give you a more organic image, better highlight rolloff and any standardised Log Gamma will make your color grading process easier as there are LUTs that convert your image into accurate colors and skin tones.
