English to Spanish Art/Literary Photography/Imaging (& Graphic Arts)

From an interview with a contemporary Argentine photographer:

There is another step in the process. After the film was developed and the results approved, I made black-and-white prints, and then I subjected the resulting prints to a further chemical process called blue toning, in which you dip the dry print in a chemical solution that replaces the black silver nitrate emulsion for blue tone color particles.


Is there something more specific than "viraje al azul"?
