Just wait a little bit more @DeeLuXe, all the images need to be approved by support staff or moderators before appearing.

Others samples:

Spiderman 4K HDR clip - 100% brightness (aut. off) - Standard image mode.

Spiderman 1080p Youtube (no HDR) clip - 100% brightness (aut. off) - Standard image mode.

**********************

 

Spiderman 4K HDR clip - 100% brightness (aut. off) - CREATOR image mode.

Spiderman 1080p Youtube (no HDR) clip - 100% brightness (aut. off) - CREATOR image mode.

----

In both cases (Creator & Standard modes) the 'Black Crush' is present (even with maximum brightness); the background scene is dark, the left tree is not seen and we can see that the Furia clothes are black when it is really blue.

 

The HDR crushes the image with black, kills the grays and intermediate tones. This is not a problem of brightness or contrast (checked), it is a bad HDR implementation (bad gamma tone).

Re: "Black crush" in HDR content, any solution?

This thread is pointless taking pictures with either a camera, or another phone, of the screen.

Not even close to what it would look like in real life.

@NunoSEN2

 

You have the same problem (green screen is because you do not ajust the white balance in camera shot).

 

Black crush and kill the contrast / medium tones.

I asked you to take pictures (and upload) on your phone. Some problem for it?

 

If you "don't see anything" It is not enough for me, I want proof.

@DeeLuXe;

 

The white balance is the same in both pictures (Medium-R0,G0,B0), I think the green is also some kind of problem with HDR in low brightness or the movie clip itself. With brightness at 100% there seems not to be the "green" issue.

I had no problems with the color tone taking the pictures (maybe it's because of the HDR). Anyway the problem is the crushing of black, which as you can see, you also have.

 

You can try with other videos that you have in HDR, you'll see that it's not just that spiderman trailer, it happens in all content in HDR. Winking Face

 

I hope SONY solves it with a new Firmware update. Thanks for your help Nuno.

More tests!

 

The BSPlayer for Android not support HDR content, but can player the clips without HDR component. This means that it eliminates the gamma layer.

 

This is the result (same Spiderman 4K HDR clip, not youtube) at 50% brightness.

 

BSplayer:

VLC player (support HDR):

@DeeLuXe;

 

I was watching the same Spiderman trailer in 4K HDR but on Youtube and there is almost no Black Cruch (and if you increase brightness - needed for HDR content -  the Black Crush is gone), so I think there might be some issue with the demo trailer that comes with the phone.
