  Photon-number measurements are a fundamental technique for the discrimination
and characterization of quantum states of light. Beyond the abilities of
state-of-the-art devices, we present measurements with an array of 100
avalanche photodiodes exposed to photon-numbers ranging from well below to
significantly above one photon per diode. Despite each single diode only
discriminating between zero and non-zero photon-numbers we are able to extract
characteristic information about the quantum state. We demonstrate a vast
enhancement of the applicable intensity range by two orders of magnitude
relative to the standard application of such devices. It turns out that the
probabilistic mapping of arbitrary photon-numbers on a finite number of
registered clicks is not per se a disadvantage compared with true photon
counters. Such detector arrays can bridge the gap between single-photon and
linear detection, by directly using the recorded data, without the need of
elaborate data reconstruction methods.
