Why Don't Camera's Have Raw Histograms?

Question for you JIm what's the latency of the live jpeg image in the EVF and what's the latency of the histogram ?

There is a need. I've been shooting in mute mode with reduced contrast so as to get some semblance of a raw histogram/blinkies. Unfortunately, it means an additional workflow step to process at the chosen profile.

Yes, it really irks when manuals for flagship professional cameras are written as if it's to be used by a P&S shooter, even worse when they appear to be written by a Japanese computer and put through a translator app.

I pointed out the differences when you posted the images. You were silent on the differences I identified.

I don't know what you mean by the word latency in this context. Do you mean the delay between the light leaving the subject and the light entering the photographer's eye? If so, the JPEG image has far lower latency, even if the camera is tethered. But for studio work, I often shoot a test image and look at the raw file, using the information thus revealed to know how much windage to apply to the in-camera histogram in that circumstance. Then you get the best of both worlds.

The jpeg image is shown near instant in my evf or lcd from memory 1/120 sec . the live histogram/zebras takes 1.5 secs to show a reading.

no i wasnt, Illah was reasponded with how many pixels were clipped and i also posted matching clipped highlights from FRV and my camera.

Show me a link to the post you made that responded to my comments on the histograms not matching.

Nonsense. You haven't done a proper test, posted some select images instead, and your in-camera histograms were clipped.

not wasting my time with no threaded view.

of cause they were clipped ,that was the whole idea. showing the fine clipping meant so you and jim couldnt disprove the accuracy. as it showed hard evidence.

By how much, in EV?

That's not the reason. Your own screenshots disprove the accuracy of in-camera histogram and totally destroy your guesswork.

Then I remain skeptical that you did that.

Good , now answer my last question .

are you suffering memory loss ? thats the question i put up.

I am not aware that you have asked me a question I haven't answered.

The jpeg image is shown near instant in my evf or lcd from memory 1/120 sec . the live histogram/zebras takes 1.5 secs to show a reading.

Your not going to respond to this ?

Is that a question? It seems like an assertion to me.
