Avatar 2: The Way of Water teaser

Comparing Desray’s Lumagen shot with MadVR, there is also different processing of the sky. Is this difference from the phone cameras or inherent in the software?

When u watched that scene, which one resemble more closely to what you are seeing? That’s the question.

Lumagen most likely, because MadVR tried to process everything to make it look nicer, skies, explosions, flames etc. Often improving the creators intent :rofl:

i was actually about to point it out, the madvr version seems like have a lot of luminance through so the sky looks to have lighter blue tone to it…

Personally I like the lumagen version… the skies look more natural… I mean personal preference la… actual colour of the sky only the colorist at the studio will know…

In real life, the colours of the sea we are seeing, is a reflection of the colours of the sky, they absorb the colours of light from the sun and rejects blue , that’s why we are seeing a blue sea. But how blue is that blue ? What shade of blue ? That is question…

Observe the colours of the sea, it looks like having too much luminance in blue on madvr . It does have the “pop” but the lumagen version looks very natural to me… I can see that as well on the skin tones of the green avatar with madvr vs lumagen.

MadVR doesn’t process colors AFAIK, but it certainly tries to lift shadows and make skies more defined and explosions more saturated. It does this not by lifting or lowering luminance throughout the frame, but just in specific areas. So, it can tone down highlights, for example in bright skies to prevent clipping, while at the same time, lift shadows in other dark areas of the same frame. You can imagine that this is computationally intensive and therefore requires a high end Nvidia GPU and up to 300W of power. It may go beyond the creators intent but reflects the preferences of the thousands of MadVR beta testers who have fed back to Madshi, the author for over a decade. So differences in green or blue tones that you see are probably due to Desray’s more expert calibration of his Sony, compared to Calman’s Artificial Intelligence and not due to MadVR. What you see here n the frame is probably MadVR cleaning up the sky so the clouds are more distinct.

Ya there is just a lot more “details” with the madvr option on the clouds, noticeable.

Just that the colours kinda look off

Does the madvr follow a specific Gamma curve or it follows the EOTF curve when tone mapping?

I suspect then it could be the RGB white balance resulting in a different tone we see between the two images…

Do you have the SDR version for avatar 1? Then from there you should be able to compare against the SDR 2020 version, to see the shades of blue on the avatar , that’s the fastest way to check if the colours are tracking closely to rec709 in SDR

I’ll attempt to take an image tonight on this particular scene, I suspect mine will display a “warmer” tone…

first picture taken by my Oppo Find X5 Pro handphone.
on my 55" LG A1 Oled, using my computer browser YouTube App

second picture using the same handphone with the 55" LG A1 Oled’s own WebOS YouTube App…

i dont know what those “White Dots” that are in the 2 pictures i have taken…
is it something like “ASH” flying around in that particular scene?

Just for fun, here are the three OLED images

Sammy :point_down:


Foodie :point_down:

Cash :point_down:

There are white dots in all three :rofl:

Cash. Is your OLED calibrated?

Ok guys, let’s throw all the guessing out the window. The image below, is coming straight from 20th Century Fox Studios. The below is the correct shade of green/ blue that we should be seeing on our screens …





This is 20th century fox image vs MadVR’s rendition :rofl:

20th Century Fox :point_down:

MadVR :point_down:

MadVR has certainly modified the creators intent :grinning:, but you definitely see more shadow detail. Interestingly MadVR’s leftmost flame is the closest to the 20th century fox compared to the others.

That’s what I thought Sammy, there is just too much luminance with the madvr

Now it’s all cleared, the reference image is straight from 20th century studios…

We can all see now which one is the reference …

I’ll go compare tonight, now that I know how it should look, it makes it easier for me to tweak it to the correct colour temperature for hdr

Now let’s see the image from 20 Century studios below :point_down: , let’s just focus on the shade of green

It’s well known that MadVR does not tone map to the creators intent, but to what the users of MadVR like :rofl: in their feedback to Madshi

I must say that the images in the 20th Century Fox look a little dull compared to what most of us are seeing on our displays MadVR or otherwise. Perhaps that’s why when you saw it in the IMAX theater, you saw the colors as dull and muted.

Hehehe!! I got no calibration tools buddy…
Sadly…
Hehehe!!
