Most of the principles of flash photography are the same on DSLR’s (Digital Single Lens Reflex) and compact cameras. There are however some differences in the way flash units are connected to, and communicate with the cameras.
It was one of those highly unlikely chains of unforeseable events that led us to Elba the pictoresque but somewhat mislaid lump of land in the Meditterean made famous by emperor Napoleon’s exile here: The fact that the treasureship Polluce was finally being excavated.
