I have always been fascinated by the luminosity of the flemish painting of the 15th-16th century. Whilst trying to find out how they did it, I came across a book that explained in a few lines about egg-tempera and translucent oil layers on top. This led me to further investigations and try-outs untill I developed my own technique, which is, for me, good enough.
Later on, through the Internet, I heard about Ernst Fuchs' so-called 'mische technique' . I never saw any work of his in real life, but it looks like his method must be at least as good, and probably even better.
Somewhere in the future, if people are interested, I might explain my way of working.
