tried that with very unsatisfying results.
because the PBR Skin Shader is like i said before, after carefully looking at it, different then Iray Uber. You will need to tweak settings.
Not sure what that $21 dollars is gonna do differently there, but but i can give it black on white to you, probably the same thing as manually doing it.
Been Busy, and did exactly that.

All Running off the SAME shader, Hair, Eyes and Skin, i took the PBR Skin Shader, Found a way around the thing it lacks, and there we go. We now have a Successor to Iray Uber.
you made a good successor to the Velvet shader.
Will reserve judgement till i see an example i like the appearance of.
Here we go, took awhile, but this is it:
Shader Itself: https://ibb.co/9NTDgcy
Shader Nodes View: https://ibb.co/8cpf49x - A Total of 121 Nodes used, and the PBR Skin Shader is now no longer just a "Skin" Shader, Everything but Glass has been defined and works with the PBR Skin Shader as its Base and Core.
Will be going into Testing Phases, but the first Quick test on a sphere has already proven Very Promising.

I prefer the shaders that come with Sol for Genesis 3 & 8 Female. Then to get good character lighting I use JoeLeGecko's HDRI Photoshoot
For other characters, I often copy hers over and replace the maps while they're still in DS memory.
FYI Edit: I also render my characters separately, which is where the magic of HDRI Photoshoot comes in
The thing with that is, that it might look great and eye candy, but not very photo realistic.
You really need to share that shader recipe.
For pbr you use the glossy reflectivity (that's the ior) and roughness (that's the intensity), the other parameters are for "artistic" materials and not realistic. In particular the glossy color is always white in real dielectric materials. The fact that the uber shader allows for artistic materials is not good for realism, also because most PAs are not skilled on pbr materials and they just rely on "what looks good" that's the artistic approach.
Anyway the settings below are also advised in the uber documentation if one takes the time to read it.

Since i'm in a TLOU Mood, i used an G9 Ellie Model with my edited PBR Shader.
Hair, Brows, Eyes and Skin are all on the same shader.

you know you can just upload images to daz gallery as an unpublished draft and then embed them in the forums, rather than making people click into some annoying image hosting website that doesnt load properly or zoom in properly?
One scene element, that usually kills realism..., well photorealism ..., is hair.
Mostly OOT hair is a good choice, but those hairs are lacking from dforce and very often they are in way to idealistic style, like hair dressers' promos.
Surprisingly, this hair turned out to be a good choice for realistic open hair.
PhilW's Suizana Hair, that in fact needs a lot of 3rd party's shader tweaking and some extra morphs, that can be achieved with d-formers.
One more issue, that is a major problem, is eye control. It is super dificult to estimate the focus in the final Iray render. What looks right in the preview, looks off in the final render.
Lightning is a combination of HDRI and cmaera headlight and exposure settings inside DS.
Only postwork done here is adding a white frame.
Since I was very interested in this topic, I thought it would be worth starting from the basics.
I found a photo from a photo studio with the light setting. Very simple. One light 45° in relation to the model and the final result. Photo.
Anyone can take such a photo in their own home using a lamp, a piece of white cloth and the simplest smartphone right ?
But. You can't do it with DAZ Studio and that's the fact.
Maybe. Maybe if someone spends a week working on preparations and postwork, maybe, maybe he will succeed. Maybe he won't get a drawing pretending to be a photo. But it does not make sense.
I'll attach this photo to you. Maybe someone can do it and I'm wrong.
wow i never knew what a photo was until your post.
Challenge accepted.
One light from the Boss portrait set with its background, one pre-prepared figure. Time from starting to hitting render - 6 minutes.
The thing is, humans come pre-prepared with things like natural asymmetry, body hair, blemishes, lumps and bumps and they generally turn out to be quite photorealistic! Daz characters are mostly symmetrical supermodels with a shader approximating skin and they need to be fettled into something resembling the average imperfect human. That takes time. A lot of time.
In your photo example I think it probably took that young lady about 25 years. It is considerably shorter using Studio - maybe a day or two.
I'm no Daz maestro but with one light and one figure, this took six minutes to create. There is no post and it could certainly use some. If I'm criticising my own render, the bump map needs to be toned down on the hands and there's some texture stretching that could do with some work. That top isn't really great for close-ups either and could have at least used a pass through the thickener plugin.
Typically this lighting pattern is Rembrandt. It's also easy to make it in DS, like this scene that I used one splotlight there in a hall with Scene Only. And there's even a product by the way... https://www.daz3d.com/artistic-lighting-kit-rembrandt-lights

It would take at most a few minutes to set up a scene like that, so you really need to examine what you consider a "fact".
There's obviously a difference between (a) performing the equivalent staging actions to set up a scene in Daz and (b) attainment of photorealism equivalent to a photograph, a concept lost on respondents in this forum it seems. So on that level, the poster had a point, albeit a very obvious one.
Why yes, you can take a simple photograph with a camera and it will capture reality (obvious), meanwhile faking realism in digital space requires a lot of effort and attention to detail (again obvious). Most 3D assets dont really support attainment of the later, so need to be selective about quality of assets you introduce to a scene.
The problem is -: do not misunderstand 'photoreal' or even that Render Mode property - Photoreal in DS...
I used to be a photographer while now photograpy is just a fun to me. I ever experimented a lot in DS with nearly all the lighting patterns I knew and used when photoshooting. With Iray render engine (unbiased PBR), DS always gives me good renders. I would say it's infinitely approaching a 'photoreal' (at least physically ray traced...) in terms of lighting results, even though CMOS/CCD etc. in digital cameras use a totally diferent photosensitive technology.
Well, 'photoreal' actually could mean a lot and depend a lot. While '3D technology' is evolving, 'photoreal' has been improved. Nowadays it's still pretty easy to tell an 'image' is a render rather than a real 'photo' as I believe we all know the reasons and tricks. So, even as a 3D hobbyist at this stage, don't be too much entangled in 'photoreal'...

My attempt (raw render)
Prrretty impressive!
Sol's shaders actually look VERY realistic. My Rosie doesn't. All of my renders you see are done very quickly and she's very (Very) stytlized compared to an actual person. But the shaders are amazing.
Of course photorealism takes work and is difficult to achieve, and the most you can do with any 3D software is approximate reality. We all understand that, so what was the poster saying? Seemingly just that you can't take a photograph with DS, which....obviously. As I pointed out, Rembrandt lighting against a backdrop is not at all difficult to stage, something the poster seemed to consider objectively impossible within DS.
Either way, the poster was saying something not very intellectual. But it's clear they weren't just saying that simple lighting set ups cannot be achieved in Daz Studio. Even by their standards that would be too obvious.
You're taking a more charitable reading of it that I.
Stylized characters and renders have the attraction of their own which I even prefer to. It may also depend on the genres of our work and audiences' preferences. Like the mangas / comics we make, less audience would care about how 'photoreal' the renders are other than the chars' characteristics, storyline, conversation, and the 'dramatic punch' from the image(s), etc.
