Skin Color..

the color of my hand. It changes as I age, and as I move inside, outside, in darkroom .

I’ve just been sorting old notes on my local drive, finding collected articles that I think must have been for something — just don’t know what. That doesn’t worry me, I collect so much more information, background to some midnight idea that is gone by the morning walk. That walk provides a different direction for the day.

“Despite the importance of reliable skin colour measurements, very little is known about the variability of these measurements and their dependency on the acquisition parameters. The main purpose of this article is to quantify the effect of these factors on the measurement reliability. Knowledge of the instrument settings that produce highest repeatability is useful for other researchers involved in skin measurements, and data on the inter-instrument agreement allows the meaningful comparisons between data sets obtained with different instruments. ” https://onlinelibrary.wiley.com/doi/full/10.1002/col.22230

“Background: Accurate skin colour measurements are important for numerous medical applications including the diagnosis and treatment of cutaneous disorders and the provision of maxillofacial soft tissue prostheses.” https://onlinelibrary.wiley.com/doi/pdf/10.1111/srt.12295

“Human skin colour measurements from four ethnic groups including 188 subjects were accumulated. Five to ten locations of each subject were measured by using two different instruments, a tele-spectroradiometer and a spectrophotometer. Three repeated measurements were accumulated for each
location. Repeatability of the measurements at different locations from different ethnicities was examined using the mean CIELAB colour difference from the mean (MCDM). The colour distribution between different locations of different ethnic groups was also studied by plotting the data in a* b* and L* C*ab planes. Systematic trends were found between different ethnicities and instruments.” http://www.imaging.org/site/PDFS/Reporter/Articles/2016_31/REP31_1_2015CIC_WANG_PG230.pdf

“The principles of color measurement established by the Commission International d’Eclairage have been applied to skin and the results expressed in terms of color space L*, hue angle, and chroma values. The distribution of these values for the ventral forearm skin of a sample of healthy volunteers is presented.” https://www.sciencedirect.com/science/article/pii/S0022202X92903477

So, those are some of the papers gathered. Several more follow the same tenor — I never finished where I was headed, I think, because that work isn’t going anywhere. The use as diagnostic? What I probably wanted had more to do with retouching, color sensitizing, attitude measurement based upon clearly gathered perceptual datasets.

Bringing this all out is the recent form of bullying —

Back to making profiles of photons on paper.
