Adjustments and Processing
Hello,
Let me ask You a question,
since Capture One is a Raw converter, It means some adjustemets are made before some another? For example, are curves before or after levels, and ICC camera profile is aplayed last or before curves adjustments? Is Demosaicing the last process always? Thanks, Karl

As to curves and levels...
You can try this for yourself to see how it works. Find an image with not too wide-spread a histogram, so that it doesn't fill the whole of the range from 0 to 255. Have a look at what the histogram looks like as shown on the curves tool, but do nothing to the curve yet. Then go to the levels tool and pull in the lower sliders so that they just touch the edges of the histogram. Go back to the curves tool and you will see that the histogram shown in it now reaches all the way from the left (0) to the right (255). So any curve you then apply is relative to that histogram. Therefore to me it makes sense to set my levels before I think of applying a curve.
But when it comes to the ICC profile, or demosaicing, I don't know.

I think the answer is that in most cases, where one adjustment affects another, the internal processing "flattens" the effect and seeks to prevent unexpected extreme results. However for editing purposes and your convenience you may wish to apply edits in a particular order. Ian's example above is making that point I think.
The Menu tabs, i have heard suggested, are ordered, left to right, in a logical order of use for the tools they contain.
In general that seems to be about right although there is nothing to stop people using tools in whatever order they prefer especially if they are prepared to work iteratively with an image going backwards and forwards between tools for fine adjustments. To that end one might wish to set up a personalised tab with the tools one most often uses.
Or, as some do, work almost exclusively with keyboard shortcuts - something that has never come naturally to me in any computer application but many find extremely productive for their purposes.

So,
First is Exposure, Color Balance and White Balance,
Then:
Camera Curves,
ICC, (ICC Saturation, Color editor)
Contrast, Brightness, Saturation
Curve,
Levels,
B&W
Here I am not sure: Clarity? HDR? Sharpening?
Thanks

It's whatever works for you and your workflow.
I will start with the Lens Tab if I have been using one of my more challenging lenses (usually old) and see that certain corrections less commonly used corrections are likely to be desirable.
Most of my images are shot outdoors and very rarely in any sort of studio or flash oriented session. So my approach may be very different to your needs.
I typically start with the (default) Colour related tab.
Set the
Base Characteristics curve to Linear Response and then check how the
White Balance looks at this point - maybe change it if it looks off and if I can find a suitable pick point on the image.
Then on to the Exposure tab.
Usually, but not always,
Reduce Contrast and Increase saturation.
A first HDR adjustment for any images with obvious highlight or dark area loss of detail (usually come back to that later but also if significant adjustments seem necessary I might change the Exposure value here - or at some later point.)
Then Auto Levels with the Auto Adjustment set to use separate colour channels rather than RGB.
Then usually, for my kit, a little clarity adjustment normally using the "Natural" method as the starting point.
I have a slight sharpening adjustment applied on import along with Copyright meta data.
And that's about it for basic settings.
Since C1 allows us to go back to any setting at any time to make changes and shows the results in real time the order of this process is not dictated by the needs of the processing engine but what I feel works for me for most of my images most of the time to reach a useful starting point.
In many cases I will then work on an image to further refine it and, more often than not, use the majority of the edits on other images via copy and paste. (In my case likely adjusting for changes in the light due to the outdoors nature of most of the shoots.)
I certainly do not feel a need nor any desire to make changes with all tools and indeed I actively try to avoid using certain tools because I prefer to find better ways using the tools mentioned above wherever possible, although I may add some curves adjustment and of course Noise Reduction and some form of colour adjustments from time to time.
Of course your needs may be very different to mine and the use of the Linear Response may not be first choice for everyone.
HTH.

Hi.
I just use whats needed to reach my goal.
With the slyders you do math and every slyder does affect a different rage and color of pixel values.0
