A light microscope comprises a light source (10) for illuminating a specimen (35), a photon-counting detector array (60) with a plurality of photon-counting detector elements (61-64) for measuring detection light (15) coming from the specimen (35), wherein the photon-counting detector elements (61-64) are configured to output respective measured photon count rates, and a control device (70) for controlling the photon-counting detector array (60). The control device (70) is configured to individually influence the measurable photon count rates which are simultaneously measurable with different photon-counting detector elements (61-64) and/or which are consecutively measurable with the same photon-counting detector element (61). Furthermore, in an imaging method the measurable photon count rates of photon-counting detector elements are individually influenced to increase the signal-to-noise ratio for the photon-counting detector array.
