Many congratulations! Well deserved indeed. PP5E was the first of Dan's books that I bought, now just over 10 years ago. It was a fascinating read and made me an immediate and avid fan. Even though it

My Photoshop version is 23.3.2, running on Windows 11. The panel works normally. The issue with the error message is familiar though. The installer refuses to work on PS 23. The workaround for that is

Massimo, adding a saturation layer is not difficult, but the question is: what should the layer contain (pixels and mask)? Do you want just a copy of the MMM Color layer, set to blend mode Saturation?

Well, thanks a lot, what a great honor. I hope and assume you and your students know that this idea is available as a real action. It was included in v.5 of the PPW panel (in the My Own Actions subpan

I am really surprised (in a positive way) to read that someone teaches digital image processing, the PPW and all underlying ideas and principles on a university anywhere in the world. Even more so tha

This is very clarifying for me (too). I always wondered, when reading about all sorts of CMYK limitations in Dan's books, how much of this would apply to high-end inkyet printing. Never did it occur t

Well, I don't think it's that bad. I am using Windows 10. Photoshop is the very first program that shows shortcomings. Whether this is caused by the specs of my graphics card remains to be seen. I not

No, I hadn't reviewed the new requirements and yes, they could well be the issue. (Stupid me.) The problem is the GPU memory: required 1.5GB (that's a lot isn't it?), my graphics card only has 1GB. Al

Jim, that's interesting indeed. Most of the bugs I encountered seem to be related with display, as if communication with the graphics card doesn't work properly. Looking a bit further, I notice that t

My first impression is rather different. Many PPW buttons cause a Script Alert "Exception:ReferenceError: ScriptUI is undefined", others do nothing at all. Just a few actually work. It's a very buggy

I downloaded this action into Photoshop. Then I opened a random image and compared its result (blur radius 2.0) with an application of USM, 100%, 2.0, 0. To be honest, I had a hard time seeing any dif

Hi Randy, I also use Windows but can't reproduce the problem you describe. All buttons work normally. For issues like this, it's helpful if you specify your exact configuration: operating system versi

This thread is a bit old (sorry about that) but this may be of interest to you. I studied the Auto-Tone/Color/Contrast menu actions plus the Auto buttons on Levels and Curves (they are all related). T

I too expect that in many cases constructing and blending extreme versions won't work. Also I agree with Dan when he says that many have a fear of the ugly. This is not a technique that I will use ver

The "careful planning" is what failed me in many of the exercises, and it caused more misses than I'd wished. So this is my most important lesson: to first analyze the image and determine the best str

Mine is 1007. Indeed, many good submissions this time. No surprise I guess, because the original is very good to start with. I expect the distinguishing features to be the shaping of the face and the

Agree, except for one thing (sorry, I'm nitpicking now). Reducing opacity of that layer lightens both sky and mountain. I'd rather prefer to lighten the sky only. But that's easily accomplished by a c

I executed the procedure that follows, and find the result (uploaded as par #932) by no means "without artifacts in the sky". On the contrary, I would say. I would never accept this for myself, let al
