Why Don't Camera's Have Raw Histograms?

Got this from B&H.

live histogram on your Hasselblad is obviously a jpeg. my live histogram/zebras didnt move when i changed WB or even DRO from one extreme to the other.

i shoot some events in Jpeg. because i can 😎

agree. my original thread. "Does Raw Histogram Matter" my answer was NO. good fun though testing with all my gear. but my A74 raws clip the same as my camera histogram, so i dont have that head room irrelevant whether its a raw histogram or not.

Everybody can. Not everybody does, they have their reasons not to.

Not my experience with the following Sony cameras: a7, a7II, a7III, a7R, a7RII, a7RIII, a7RIV,a7S,a7SII, a9, a9II.

Not according to the raw files and back-of-camera shots you posted.

Sorry, but my answer is NO, you are not testing. Tests have protocols, and they are systematic.

they lack confidence knowing they make mistakes.

you keep quoting the same cameras. do us all a big favour and post a live histogram from any of those cameras.

ROTFLMAO

argumentative. holds no substance.

😁

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.
