Scene luminance has nothing to do with exposure.

Nope, don't own Sony cameras but I've just picked through the Sony manuals for your camera and found that the zebra indicator is anchored to IRE levels, a video convention for expressing the range from black to white in a composite signal - definitely not raw.

Me too!

Opened in the GIMP, masked the lamp (not v. well), dialed it down a bit, applied contrast and brightness, three stages of USM, then "oilifield" ...

... the GIMP - don't leave home without it.

Pardon the typo.

I use GIMP mainly for clone/heal, and once in a while I'll mangle an image in to abject abstract-ness with it. Definitely OT to the thread, maybe I should start a PlayRaw thread with the raw file. Oops, wrong forum... 😆

It's astounding the sheer number of options available in the GIMP, even with no add-ons.

I use it mainly for analysis but layers and masks are extremely useful when messing around ...

it was about 50 times you just dont accept you dont know everything.

no you dont your an m43 shooter

I was expecting a somewhat more on topic response, with examples proving your point of view.

no one said its from raw . please read every post again. its as close to raw as you can get , which part dont you or anyone eles understand

revisit the other 1000 posts to re familiarize yourself.

So, you can't offer factual proof.

Translation for readers of English:

I think your problem is that you are a conspiracy theorist and believe that everyone is lying to you, but it is actually the other way around.

I shoot mostly with Nikon, Leica, and Hasselblads, but enjoy using other brands as well.
I just returned from a 5 weeks trip in Europe where I used only a6600. Looking forward to the upgrade in a month, though.

I even posted images here in Sony APS-C forum.

I do get it. I currently use a metering mode that protects highlights but leaves 1-2 stops of unused headroom depending on the scene. As good as I can get with my camera and shooting considerations. I'd just like a more direct means to assess blown highlights, one that is directly associated with the measurements being blown. Based on IRE, Sony zebras wouldn't be it.

Very simple to put my area that I have selected to be as close to white without clipping in the raw file, Most of the time this is done using the cameras metering system ( that is calibrated for raw shooting) or by an handheld meter with an +ec for raw.
To do this I measure the scene luminance

This is not done on someone with a dark complexation, or light, not on middle grey those are set by processing

What am I to gather from from these 2 histograms of the same image?

thats the thing. my camera histogram matches the raw histogram using fast raw viewer not just the zebras. But the zebras are far more accurate
unless you use a 3x jewellers glass to view the tiny camera histogram. as fas a i know sony is the only camera system that has raw accurate tools.

i dont know what your looking at.

This was disproved.

Didn't find any promise of "raw accurate tools" in Sony manuals.
