Re: Live View Boost & the Histogram

I think this is a (legacy) issue from earlier versions of the TruePic engine which had less processing performance. By applying all the settings effects (including Art filters and Vivid/other image adjustments) before generating a JPEG for the LCD/EVF and then computing the histogram from the resulting downsized image this would minimise the required computation (and time) - hence allowing higher max frames/sec etc.

It is also logical - for those shooting JPEG and applying adjustments & filters that the LCD/EVF & histogram should bear a closer relationship to the 'finished image'. Clearly however this relationship goes pear shaped when LV Boost is applied and some words in the manual reminding users of this would be useful.

Whilst, like you I only shoot RAW, I think it would be complicated/potentially unreliable to have the histogram generation method change according to image storage mode.
