Maybe I’m just old and senile. I found that page a couple of weeks ago, and if I remember correctly, it was suggested I open it in Firefox, so I installed Firefox.
To someone who knows next to nothing about PhotoLab 3, that page is totally confusing to me. Once I know more, it will be invaluable. What works for me, is to open one of the “how to” tutorials in my browser, open the DxO software, and whatever the fellow does in his video, I try to do the same thing on whatever photo I’m working with. It is very slow going, especially because I’m making notes, but presumably at the end of each step, I know one more thing about whichever DxO software I’m working with.
Not sure which version of PhotoLab you are working with, 2 or 3. I bought 3 but apparently I now also have 2 because it came along with Nik Collection, and I haven’t yet tried to remove it.
If I’m ever going to learn the DxO software, it will be through using it, and as I find something I want to do to my image, I try to find a video showing that.
The instructive web page didn’t seem intuitive at all to me, probably because I’m slow, old, and dense, and new things slowly sink in. I don’t know enough yet to correct an entire image, but once I know the “vocabulary” I hope I’ll have a good start. At that point, your write-up will certainly help me.
I know what I want to do to an image (such as my post about converting a gray sky to blue) but it seems like a struggle to find an answer. I’m 99% sure it’s somewhere in the “color wheel”, but to use that, I have to select a color before I can modify it, and in my case there’s no “color”, just gray.
Thanks, and thanks for taking the time to create your write-up. Like I said, at some point it is going to be a huge help to me, but I’m still in either kindergarten or the first grade… 
…and despite that, I do usually succeed in improving my images, somewhat with “trial and error”.
