Resumo

A coleção de fotografia do repórter Roland Oliveira (1920-2007), pertencente ao Sport Lisboa e Benfica, contem cerca de 40 000 negativos de gelatina e prata 35 mm, que se encontram enrolados e endurecidos. O presente estudo procurou fazer um levantamento dos atuais procedimentos de conservação e restauro levados a cabo em instituições portuguesas detentoras deste tipo de materiais, através da realização de um questionário. Tornou-se assim evidente a necessidade de desenvolver tratamentos que permitam a planificação de películas enroladas. Como tal, desenvolveu-se um tratamento de desenrolamento e planificação, de forma a restaurar o estado inicial do conjunto de negativos em estudo e possibilitar o seu manuseamento, digitalização e acondicionamento adequado. Este baseou-se num processo de de-shrinking (câmara de vapores de glicerol, acetona e água), adaptado da bibliografia de conservação e restauro de películas cinematográficas, combinado com a planificação sob pesos. Este artigo discute a metodologia adotada, que permitiu alcançar resultados positivos.
