  We present a technique based on multi-photon detection which leads to a
strong focussing of photons scattered by independent single photon emitters.
For N single photon sources it is shown that if m - 1 photons are detected in a
particular direction (with m \leq N) the probability to detect the m-th photon
in the same direction can be as high as 100%. This measurement induced
focussing effect is already clearly visible for m>2.
