Develop Persona - Clipped Tones

Recommended Posts

Hi pjglad,

 

Show Clipped tones when enabled will show all the clipped midtones areas with a bright yellow colour. This then allows you to use the tools such as Exposure to adjust your image.

Actually, I'm confused. What are clipped midtones?

Show Clipped Tones

Would love to understand too. Also checked other forums, including the Workbook, and Betas, but while it's often mentioned, it's never defined in a clear way.

Thanks so much!

Easiest way I can think of to explain this is (referring to the Histogram),

From Left to Right, Black Tones, Shadow tones, Mid Tones Highlights, Whites. So if you clip any tones, they're too bright or too dark.

Here's a good article explaining Camera Tones, Histograms, ect. https://www.cambridgeincolour.com/tutorials/histograms1.htm

Mid tone in this context does not make much sense. Yes, colour can be a mid tone and still have one colour component clipped or missing. Like 100, 100, 255. Point is that if one colour component is clipped or too low, you can correct.

Seems to me that the Clipped Tones warning in the Develop Persona responds to Contrast adjustments. It drives me bananas trying to adjust for it, so I don't use it. Way too sensitive. In developing my RAW images, I don't mess with contrast adjustment in the Develop persona, since I'll be dealing with adjustments that affect the contrast in the Photo Persona.

Thanks very much. I do so love the articles in Cambridge in Colour too.

I am pretty comfortable working with histograms, and am quite clear on lost shadow detail and clipped highlights, ETRR and blown channels and such, but "clipped tones" seems to be an Affinity-specific warning. It has never been explained by Affinity, aside from the several very generous and considerate musings and conjecture contributed by users here on these forums, but has yet to be confirmed by Affinity, so I was hopeful that someone authoritative might write a sentence about it for the user community.

I am investigating every possible slider for any explanatory effects or explanations.

Develop Personas, under Tones, Split Toning, changing Shadow Saturation percent affects the yellow warning in a big way. Detail refinement (under Detail) for larger radii when coupled with larger sharpening amounts also seems to have an impact. Raising (darkening) Blackpoint levels (under Basic) impacts it, whereas lowering it (brightening) makes it go away at slight increases.

Therefore, in the spirit of true Wiki-based support, I surmise that it's presence can only be symptomatic of severe transmogrification manifestation levels.

In addition to manifestations of severe transmogrification levels, it appears that photos of transparent faeries riding on blue unicorns in close proximity to the camera may also create images that trip the yellow "Clipped Tones" warning.

Also, when there are so many mid-tones that they even spill out the top of the histogram, that's "Clipped Tones" too.

If anyone knows of any additional purpose of this switch, and how to correct for this warning, that would *really* be much appreciated. I already have loads of speculation across the fora for the last half year: I had been hoping to find an authoritative alternative.

Thx! :10_wink:
