Resumo

Este artigo discute dois métodos fotográficos baseados no uso da radiação ultravioleta para o exame de obras de arte: a fluorescência de ultravioleta (UVF) e a reflectância de ultravioleta (UVR). Enquanto a fotografia de UVF pode ser efectuada com qualquer máquina fotográfica digital, as imagens de UVR são adquiridas com uma máquina fotográfica digital modificada para espectro completo, sensível à radiação ultravioleta com comprimento de onda até cerca de 360 nm. Esta modificação envolve a remoção do filtro interno sobre o sensor CCD ou CMOS de forma a tornar a máquina sensível à radiação ultravioleta e infravermelha. Este artigo descreve os procedimentos e o equipamento necessários para a realização desses exames, discutindo quer estudos de casos quer os resultados obtidos com amostras preparadas com esse objectivo.
