Highlight clipping warning (vs Lightroom)
The same image displayed in C1 shows more highlight clipping warning than Lightroom. Is this because the default setting in C1 is level 250 whereas LrC must be 255? (There appears to be no option to change this in LrC.)
Changing C1 to warn at 255 seems to solve the problem, but that leads me to ask, why 250 as default?
Just trying to understand the subtle differences.

Why not ? 255 is no use (are you sure you can't change it in LrC ?), as it is the maximum value of the histogram. Too late !
In Capture One, 250 seems to me a good value, and you can change it as you like.

My understanding is that Capture One's defaults are to provide a more pleasing contrast when viewing. I've set my highlights to be 253. You can set either limit to whatever you desire.

Don't forget that the clipping value doesn't change the image, but only warns. The contrast is adjusted using the levels tool, among others.

A highlight default of 253 highlights images with color still present, though verging on being clipped. Set at 253, adjusting the image until warnings are eliminated, may exceed what you need to prevent clipping. Anyway, how close to being clipped a part of the image is seems to me to be a matter of personal preference and depends on the artistic intent.

I've heard/read that when printing images you never want an area with no ink. Don't remember where. I haven't experimented/printed enough to know if this is something that can easily be seen or if it is a rule in the theoretical search for perfection. In any case anything clipped to 255/255/255 will leave an area on a print with no ink unless otherwise edited to change the output.

marco, you are correct because ink covered paper and plain paper reflect light different so depending on the printing process and paper this can look rather ugly. for offset printing I always set a minimal printing dot but unfortunately the best way to do this is by using an image editor and not a raw converter. but trying to keep everything below a certain clipping point in the raw converter as a general rule is also a very bad idea when your image contains for example specular highlights. there is nothing like a perfect clipping point setting as it depends very much on the image content what is right.

You are right Marco. It is far better to avoid burnt areas (255x3), in picture edition, but first and mostly when shooting.

Thanks for all the comments. I think C1 is a little more conservative than what I'm used to when using LrC. What's interesting is that with a default unprocessed uncorrected raw file C1 and LrC give different highlight warnings even with C1 at 255. It is all subjective (up to a point) but I was worried that I've been sending out files with clipped highlights.
LrC and C1 speak a different dialect, sometimes I'm not quite sure I've heard correctly!0 -
tone curves are different with c1 being more contratsy and different color spaces also lead to different channel clipping. furthermore LR applies a smart highlight compression in the background.

Ah, thanks, interesting.
Despite what people say, I find there's no visible difference in colour etc between C1 and LrC. For me its the user experience which is different.

agree, most user see better color from c1 because they what to see it and they often confuse contrast / tonality and color too. looking at color rendering only they are very similar or easy to match.
I use dxo, adobe and c1 and the main difference in my view is how they handle tonality / contrast / micro contrast and this can lead to very different end results.

Yes, indeed. The HL and shadows clipping depend upon the colour space you work into. Switch from Prophoto to sRGB on green saturated tones and you'll see the difference. This is very useful when you soft proof an image before printing.
