Live View Histogram v playback histogram

[crockny]

Why does my Live View histogram differ slightly from the playback histogram, and which is more accurate?

Raw or JPEG?

I would have to say that the playback histogram is more accurate since it has to make fewer assumptions about WB, et al.

[crockny]

I'm using the 5D Mark III and shooting RAW.

[kvbarkley]

The histogram for *both* is an approximation since it displaying a histogram for the jpeg from the internal JPEG engine. I can easily believe that the LiveView histogram is a histogram of the live view display which is a speed-optimised jpeg/video display, *not* the fully-processed JPEG.

[crockny]

So you are saying that the playback histogram is more accurate?

[kvbarkley]

As far as it goes. The playback histogram is still based on the JPEG data, not the Raw data.
