Resumo: The photographic collection by the sports photographer Roland Oliveira (1920-2007), belonging to Sport Lisboa e Benfica, is comprised of an estimate of 40000 images captured in 35 mm silver gelatine negative film, which are currently rolled and stiffened. This study has strived to survey the current procedures undertaken by Portuguese institutions concerning the conservation of these type of materials, by conducting a questionnaire. It became evident that new treatments to allow the flattening of rolled films were needed. Therefore, a conservation treatment was developed to unroll and restore the original flatness of the negatives under study. The main purpose of the treatment was to enable proper handling, digitization and storage of this collection. The developed procedure was based on a de-shrinking process (chamber with vapours of glycerol, acetone and water) adapted from the conservation of motionpicture film literature, combined with flattening under weights. This paper discusses the adopted methodology which allowed to achieve positive results.

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.ARP - Associação Profissional de Conservadores-Restauradores de Portugal2022-05-31info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://doi.org/10.14568/cp2020072eng2182-99421646-043XSilva, JoanaGarrucho, SandraCarvalho, Filipainfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2024-05-06T11:21:24Zoai:ojs.revistas.rcaap.pt:article/25080Portal AgregadorONGhttps://www.rcaap.pt/oai/openairemluisa.alvim@gmail.comopendoar:71602024-05-06T11:21:24Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
