iPhone screen shots as follow

This is also what I’m seeing with the iPhone …

I’m not sure what’s the directors intent, but I strongly believe the scene is meant to be dark, where they are transporting the slaves in the jungle and the main focus is the princess … I’m sure the captors don’t want light and don’t want to be seen, hence they travel through a dark route through the jungle

Are we supposed to see everything is the question

That’s what I’ve been guessing… so that’s why I find this jungle scene has to be dark , I can open up the iris to see everything, then the APL goes up and it starts to look grey…

Everyone is correct. ‘Reference’ is everyone preferences. :sweat_smile:

Could be age too. Cannot see in the dark anymore :rofl:

Sometimes we are comparing apples and oranges too. My Disney+ source for the OLED is Dolby Vision, which has tone mapping built in whereas a 1080p SDR source may look quite different on an OLED that has high dynamic range

I’ll try over the weekend. Very busy this weekday.

Just saw your post and request to check this scene. I pulled out DV and SDR versions.

Sorry my mobile camera cant take a decent accurate photo of my oled. This scene is v challenging for camera. Either it brightens it up too much or crush the blacks.

For dv video (factory default calibration ad calman dont fully support dv calibration),

  • overall presentation is closer towards the oled image u shown here.
  • But on mine, i see more shadow details and less black crush compared to your above images.
  • For the lady on right, i am able to see the scarf clearly without black crush, less black crush than your image above

In my sdr video (fully calibrated to 120nits), the presentation is slightly different

  • the background blacks are slightly brighter.
  • So sdr image has a slightly brighter presentation than the dv image in terms of the shadow detail/ brightness of background surroundings.
  • @sammy, your pj image, is sdr right? My sdr image’s black levels is close to that but darker.

The scarf of the right side gal, i can see the scarf clearly even though it’s very dark. So @ronildoq, your oled image for that scene looks like got black crush. U shld be able to see the scarf clearly in black. And not overly bright

Dont lose too much sleep over the small differences in the photos. The camera could be playing tricks, brightening or crushing the blacks.

Best is to see the actual video with your own eyes to compare.

Yes there is. There is a hanging white light bulb in the jeep. So a slight white light.

But the image/blacks in matrix’s photo is overly bright/lifted. Either camera is playing tricks or blacks are lifted too much

So many people interested in this scene :joy:. Maybe I’ll try to take a snapshot later today and post it here.

Oh yes you are correct, so there is a small bulb hanging at the back of the jeep. Thanks for confirming

The image I have shared is coming from this YouTube marvel entertainment source, can u see again if this is what it’s showing on your OLED SDR with a quick image capture on your HP?

It is an SDR source from YouTube , the image I shared from screenshots confirms the same . I’m not able to see the full shape of the scarf of the lady on the right on 3 devices, the pj, the OLED and the iPhone

If it is still able to see the scarf of the lady on the right in full, that means I know the issue

The playback is happening using the native built in app on the OLED , that means the calibration could be independent on this OLED C7 model. The last calibration done with this OLED was with Oppo 205 in the chain…

Ya do share this on your set up with the normal settings u use on the PJ for all content

The source with SDR from that YouTube link vs the dolby vision version. That should confirm it. Oh by the way, was your jvc also calibrated for DV ?

No.

This 2 timestamps are very good / ref to test correct black levels (lifted blacks and black crush). Even for an oled.

I find the other “difficult” scenes in this demo clip that is excellent to test black levels:

  1. when the bad guy commander 1st gets off the jeep. The scene shd very dark w the forest surround inkly black, and commander’ body also dark cos there is no light, just like in a forest w no light beside the vegetation (rem our army nsf time?). Check the black transition betw his body and the background beside him. If no calibrated well, u w see lifted blacks (obvious dark grey) or black crush (cant see much of the commander’s body when he moves towards the camera). I find this 1 of the most challenging scene to be presented well.

  2. when the commander walks towards the truck with prisoners, showing the dirt road. Check the brightness of the dirt road. It shld not look like a lighted up road where the sand is bright, because there are no lamppos! But a good balance of dim light and yet see the details. I find the dv video presents this better than the sdr video. My Sdr video (bd disc playef from oppo player) seems to present the road slightly brighter

It’s ok no worries. Do share the image for this scene on your JVC using YouTube clip SDR (which I believe is calibrated) and also the bluray DV version of the same scene together with the brighter election scene about 18mins time stamp, this one below :point_down: , using the same gamma- iris settings on your PJ

From the above, will be able to deduce. There will always be a sacrifice between the black levels vs the shadows. That will give us a good idea on how to strike a balance

Bro, shld be able to see the scarf of righthand side clearly but just nice without black level raised. U know it’s raised when the scarf becomes a little bright and the surrounding of it also brighten till u can see the truck inner color brightened.

On my dv and calibrated sdr, can see outline of scarf clearly (just nice transition to the surroundings) but the inner of the truck still dimly dark.

Test dv + sdr version on your oled and pj. See got any diff? :slight_smile:

Oh so u can see this section on your calibrated OLED SDR image ? We’re u using the YouTube link above ? As in not the Blu ray source

Can u also share the photo of the same scene in DV together with that election scene ? I wanted to see how much blacks sacrificed in exchange for shadows

My mobile camera cannot take the dark scene well. The photo result is v bad ha.

U free come over la bro one night. We not far from each other.

I dont prefer youtube to compare cos i scared youtube compress videos affecting video quality compared to disc or the direct source file.

Bro Foodie, you are spot on, it’s not camera issue, my blacks are lifted too much, I realized this issue when Bro Bryan pointed this out, and this is my 1st priority to improve…

Alright guys, don’t get too excited over this particular scene as it is very hard to capture scenes with so low APL. The normal phone camera CMOS sensor simply not big enough to capture all the details and let’s not forget that one will have the play with the ISO and aperture to capture the “actual” representation of what we really saw on the display, be it projector or OLED TV. I will be frank, even using my Canon EOS M50 MkII, I am still struggling to capture the “actual” representation of what I saw on my JVC NZ7 projector.

Below is the best my Canon M50 camera can do. I will provide an exposed ISO set at 6400 with an aperture of F1.4 and a shutter speed of 1/60. Source from Disney Plus as I do not own the physical disc.

Here’s the image produced from my JVC NZ7 projector with Lumagen Radiance Pro doing all the Tone-Mapping.

As you can see, the girl’s head scarf on the right, I can still make out the outline.
