Could someone point out the basic differences between highlight, white, brightness ?
Would it be possible to quickly explain the basic principle difference between highlight, white, brightness controls ? Thank you.

The brightness control works on the middle of the tonal range, and has little effect on the dark or light end of the range. (So it is like increasing or decreasing exposure in the middle tones only, unlike the exposure control which shifts the whole tonal range.)
The highlights slider is like brightness targeted on the lightest parts of the tonal range, mainly the top quarter or the top third of the tonal range. The white slider is like brightness targeted on the very top end of the tonal range, reaching far less into the mid-tones than the highlights slider does.
A good way of getting the feel of what they each do would be to observe the changes in the histogram when you use these sliders, and observe the changes to the visual look of the image too.

Thank you :) I suppose that shadows, black etc. work in a similar way :)

That's right.

Ivo,
For visual representations check out some of the recordings of the most recent on-line live stream events.
From memory this question has arisen and been answered in almost all of them so it should be easy to find one with appropriate visually supported explanations.
You can also see the effects on your images by observing the effects of the adjustment on the various Histograms available.

Yes, sure ... The only slight problem with this kind of "live streams" etc. videos is that they are overloaded by lot of plain talking while the concentrated points could often take 10 times less :)) First 3 min some hello, how are you etc :))

Then skip through on these relatively short sessions using the video bar and pick the sections that look most likely.
On the Main scheduled webinars the notes usually have some sort of time based index that may help.
But it was just a suggestion. If you are happy with the answers provided in writing and don't feel the "visuals" will offer any benefit then don't watch them.
If still not sure?
Then pick a small number of reasonably well exposed sample images, make sure you have some of the histogram tools visible, move the sliders around and watch what happens. The difference in results should be quite visible. Being comfortable with understanding how to get the optimum results, for your needs, from the adjustments may just take a little experimentation.
HTH.

Also there was a great live half hour session on this a week ago, which I have just got round to watching. It explains how these things work really well - David Grover from the Capture One staff brilliantly clear as ever.

I could also recommend any of Paul Reiffer's recent C1 Editing session videos on You Tube (and probably elsewhere). One on the C1 channel with David Grover, several on his own channel.
The Tool (and complementing tools) of your interest are mentioned, described and demonstrated several times per session usually across a variety of image types.
Speaking personally I find them about the most watchable and engaging sessions I have found so far.
