Scene luminance has nothing to do with exposure.

sacasium 😁

thank you, you have just proved my findings and point. so if the camera live luminousity histogram was sampling the jpeg then the camera histogram should have been highlight clipped quite a lot.

but guess what ! "IT ISNT"😎😎😎

and btw the faststone luminousity histogram reads both raw and jpeg and you can flick back an forth to see the difference as well.

no it isnt ive even looked through a jewelers loupe 😁
will post anohter one today with a sharper image of the histogram.

Thats why i prefer the faststone raw luminousity histogram, which i did post.

Do you know that luminosity histogram depends on colour model, most influential is green, with little input from red and even less from blue?
Classic luminosity is calculated as 29.8839% red, 58.6811% green and 11.4350% blue NTSC linear gamma.

FastStone histogram isn't based on raw, and there is no luminosity until a colour model is applied, so no luminosity for raw.

So is in-camera histogram.
There is no in-camera JPEG that you can access, but there is out-of-camera JPEG. Those are two distinctly different things. The camera uses video processing to calculate live histogram, and guess what video processor works with...

It's your time to waste.
The only proof of your method would be each and every one of your raw files taken under good light to be exposed to the right.

yes there is . and you can have display a RGB histogram for that in playback.

You dont know, and niether does anyone else. your only speculating.

I have already posted the out of camera image. take it into photoshop and read the numbers.

again only speculation on your behalf.

I do know. Lots of people do know. Lots of people design cameras, hack firmware, and simply know chipsets. It's you who don't know, and you don't want to learn.

lets get this straight AGAIN. the incamera histogram represents at best, the raw file NOT the Jpeg. which part do you not understand ?

The part where you are wrong ~<:-)

game set match.

just took an image of a white globe ceiling light. the 16 bit converted raw read 250 250 250 the jpeg was over 255 255 255

here is a 1:1 image of the tiny camera histogram LOL

speculating is haveing no proof. i have presented the proof may times. you prove me wrong. Oh you cant because you dont own a sony 😜

Thanks Ian, you gave me a hint to the final peice to the puzzel. everyone was just to rapped up with the raw file putting up so many auguments and not the jpeg.
best part is ive taken away the grey areas ,there is no more. KISS has beaten you all.
now for the 7 year old a6300 😁
