Our latest paper on the restoration of daguerreotypes using laser and atmospheric non-thermal plasma methods is now available. Have a look at the link below
Daguerreotypes, with fragile surfaces, suffer from tarnish and harmful residues left by cleaning attempts. Our latest study explores innovative ways to restore them, safely and effectively, using laser pulses and non-thermal plasma.

Setting up a methodology for restoring degraded daguerreotypes using UV lasers and atmospheric non-thermal plasma cleaning techniques
Since the early years of the development of daguerreotypes – the first commercial form of photography made public in 1839 – cleaning procedures have b…

🎂May 23, 1667 Jacob Cristoph Le Blon born in Frankfurt am Main, Germany 🇩🇪
In 1710 he invented three color printing using an RYB or RYG color model which later morphed into the modern CMYK system, better for printing.

I updated this chart, which I made a few years ago. I like the clustering and how the tails help tell a story. This is a particularly useful application of connected scatterplots. Not sure if two juxtaposed line charts would communicate better. #30dayChartChallenge.

Our recently published paper focuses on the stratigraphic structure and chemical composition of historical photographic negatives. We used linear and nonlinear techniques to investigate the gelatin-base emulsion layers over glass supports. Have a look here 👇🏾
Historical photographic negatives are fragile due to their composition and stratigraphic structure. Our study, part of the #DIAGNOSE project, used advanced techniques to analyze these factors, contributing to conservation strategies bit.ly/42mQiNB

Thread - I've been thinking a lot about Walter Lippmann’s Public Opinion lately, especially in the context of Musk’s role in dismantling the federal workforce through DOGE. It’s a perfect example of what Lippmann warned about over a century ago.
