In our newly published study, we present the first open-access dataset of spectral reflectance from natural objects in Northwestern Argentina. This collection includes 532 samples from a wide variety of plants, animals, and stones—measured under controlled lighting conditions using a SpectraScan PR-715 spectroradiometer inside a custom-built diffuse illumination cabin. Why does this matter? The way […]
This dataset currently contains the spectral reflectance of 532 samples of natural objects, ranging from 400 to 1000 nm in four nm increments. These records correspond to plants (302 samples), animals (167 samples), and stones (63 samples). The objects were collected in the field, purchased at local fruit and vegetable markets, or borrowed from museum […]
During the third week of December 2024, members of the VNL team, together with Dr. Alejandra Korstanje (ISES, CONICET-UNT), conducted a scientific campaign to collect spectral data in the natural landscapes of Barranca Larga. This village, located 2500 meters above sea level in the pre-puna area of the province of Catamarca, Argentina, was the ideal […]
“I had the opportunity to participate as a presenter at the 31st young researchers conference, organized by the association of Montevideo group Universities. During this event, I presented my work entitled “Using digital photography for animal color quantification in biological research”. This interdisciplinary conference, which brought together young researchers from across Latin America, was held […]
José Fanchini and Pablo Barrionuevo participated in the 27th International Colour Vision Society Meeting held in the beautiful Ljubljana, Slovenia from July 5 to 9, 2024. During this meeting, we presented two works that were conducted in the VNL. José presented his work on the development of a five-primary portable photostimulator suitable for carrying out […]
