Ended up with a new, new PC that is also a Dell workstation running Windows 11, 64 Gig Ram, 4TB storage, Adobe Creative Cloud, latest versions, etc. I have installed PPW and can get the scripts to run, e.g., MMM + CB, which I use a good bit. However, running in this fashion is not the same as when I ran it from the power panel.

Under the Window, Extensions(legacy), PPW 5 appears but does not run. I receive a message that extension PPW Tools 5 can not be run because it is not properly signed. Version 5.0.0 with The path: C:\ProgramFiles(x86)\CommonFiles\Adobe\CEP\extensions\com.cromaline.PPWtools_5 .

What are your thoughts?

Thank you.

Development of the panel has pretty much stopped. I did however ask my list if anybody had the same configuration, and one guy replied that he had installed successfully using the Manual Installation instructions, which are found here.

I just received my new Dell workstation with Windows 11 installed along with the latest versions of LR and PS. Unfortunately the installed does not work with this platform; will there be an update?

I had been using PPW tools on my prior computer which had Windows 10 and latest PS versions so its not clear what WIN 11 is doing to prevent installation.

I would appreciate your guidance.

Kind regards,

The brief answer is no. The idea of 16-bit superiority in real-world photographs still has the characteristics of a religious belief, so no amount of proof can convince its adherents otherwise.

As noted in 2005, testing shows that no realistic processing of photos in sRGB or Adobe RGB is affected by bit depth. In grayscale or ProPhoto RGB, there sometimes is a difference, roughly described as a very slight blurrier appearance in the 16-bit. As I pointed out then, this is beneficial in such things as skies, but harmful in objects with fine detail. So, in most cases no visible difference, but where there is, viewers are likely to prefer the 8-bit version about twice as often as the 16-bit. Now and then we see people producing one of the ones where 16-bit ProPhoto gets a slightly better result than 8-bit and claiming it proves that we should use 16-bit all the time, ignoring the examples where 8-bit gets a better result.

The most important subsequent testing was more than five years ago in preparation for my latest books. I was considering a workflow that might be suspected of enhancing noise, so it became necessary to perform the tests that the 16-bit advocates had been refusing to perform all along: large moves in Camera Raw compared to similar ones in 8-bit LAB.

The results, and an example was posted in each book, were conclusive. For most images it doesn’t matter, but for those that happen to be prone to noise, one gets far less of it in 8-bit LAB than in Camera Raw. IOW, the 16-bit advocates could have found out all along by testing that the method they were advocating wasn’t simply no better than the alternative, it was in fact significantly worse.

I’m happily using the free part of the Variant Manager that comes with the PPW-tools panel.
Is there extra functionality in the paid version?
And where can I buy it?

Thanks for your books and tools,
I use them every day.
