CyberLab Megatron 4K HDR Game SNES Composite.slangp
@Hyllian, I used Pro Mode, ISO 250, Speed 1/60, Manual Focus and Auto WB for these pics. I almost never use Auto Focus and most times I use manual WB at around 4300K.
The new ‘crt-sines’ glsl (still on PR). Real Trinitron colors on by default compared side by side with a real crt, convergence options in all directions etc. And as usually really fast.

Actually trying to make a preset for high brightness 1080p monitors with a decent black levels, so i’m trying not to sacrifice masks (too much).
Suggestions?

Playing some Amiga gems, so taking a break from scanlines, Amiga Games were tuned for shitty signals imho.
…the first time i saw “double dragon” on a 1084s my impression was really bad, then I saw (and heard!) Blood Money intro on a PAL tv and i felt in love

I used nVIDIA Shadow Play to take these but there are other methods available.
The files can also be viewed on an SDR display by the way.

A little experiment.
In the first image if you look closely at the ceiling, or at other dark areas, there are several black dots. I think they’re there for some kind of dithering, to have some sort of shadow effect, but even with my usual settings, which aren’t thtat bright, they’re noticeable. Looking directly at the monitor and not at a screenshot, it’s worse.
Messing around with the usual settings (brightness, bloom and such) didn’t do the trick. I think that the main problem is just the LED technology, which lacks something in the contrast/black areas (I have an Asus MX7AQ monitor, not bad at all, but still). So here’s what I did: I’ve added a little of Black Level (value: -10). That seemed to work, without impacting too much on the overall balance of the image (second screenshot).
Modifying the Contrast value produced a similar effect, but impacted more on the overall balance of the image. So, Black Level is the way to go if you have a similar issue.
Let me know what you think (open in a new tab).

Lots of games require brightness or gamma adjustments. (Especially arcade games) Bottom pic definitely better
Here are some more HDR screenshots, showing the blending of dithering in some TurboGrafx16 games in order to make new colours while attempting to preserve some sharpness.
The following files are all in jxr format so you’ll need a jxr viewer to view them if you’re not using Windows 10 or 11.

Here’s a link to a jxr viewer. The native viewer in Windows 10 and 11 is probably better though.
View popular high dynamic range (HDR) image formats, including OpenEXR, Radiance (.HDR), DirectDraw Surface (.DDS), and JPEG XR, in their full quality on a capable HDR10 display. https://apps.microsoft.com/store/detail/9PGN3NWPBWL9
