The optical and morphological properties of resveratrol were investigated. This nontoxic fluorescent natural material, emitting in the visible blue light, was used as an optical marker, enabling the enhancement of the image contrast coming from relief pictures marked on challenging surfaces. By applying appropriated imaging softwares, this marker was verified to be very useful in the latent fingerprint recognition deposited on different wood surface types, mainly those with high level of roughness, where conventional forensic materials do not allow effective fingerprint image visualization.

This paper is about Technical and Scientific Imaging for caving painting (archeological site in Brazil). High quality imaging with color management has been used, in addition to scientific procedures to generate digital images, capable for recording not visible light (ultraviolet and infrared radiation). In addition, the RTI (Reflectance Transformation Imaging) technique was used. Rock Art is a kind of Cultural Heritage, extremely fragile archaeological remains and susceptible to a series of factors (physical, chemical, anthropic and others) that can cause different impacts for their preservation. The Rock Art can suffer an irreversible damage, which can greatly compromise research and relative studies, then, requiring great scientific and technical procedures for imaging.
