character_diamond Exposure When [V-Log] Is Set

The [V-Log] curve characteristics comply with “V-Log/V-Gamut REFERENCE MANUAL Rev.1.0”. When set to [V-Log], the standard exposure when gray with a reflectance ratio of 18 % is imaged is IRE 42 %.

		When [Photo Style] is set to [V-Log]
Reflectance ratio (%)		IRE (%)	Stop	10 bit code value	12 bit code value
	0	7.3	—	128	512
(1)	18	42	0.0	433	1732
(2)	90	61	2.3	602	2408

When luminance is to be displayed by “Stop” units, this camera calculates IRE 42 % to “0 Stop”.
