You don't need to have expensive studio flashes to achieve excellent results.
I recently finished a memorable two-week-long photography workshop in Gran Canaria for the Mapfre Foundation on the theme low-cost lighting.
What I wanted to demonstrate with this workshop is that we don't need to have expensive studio flashes to illuminate a scene and achieve excellent results. The tools that we used instead where things that we all may have at home. Things like torches, lamps, candles... and so on.
And in the last day of the course, attendants had to create a little handcrafted book to present the pictures taken along the workshop. I was amazed by the high quality and creativity I saw.
