with the naked eye. what we can see here is basically, the light coming from our object at different wavelengths. we can select the wavelength that we want to look at, and this amount gave us initial information of our material of our sample. different points on the objects can be selected to examine closely, with information given about similarities and differences between pixels in the image. once all of the information is collected, an algorithm will suggest how it thinks the pieces fit together and what's missing, and run it past a human expert. if this works, i think it will have a huge potential in future projects, both in pompeii and elsewhere, for not only wall paintings but also pottery fragments, which is the majority of finds
