1. A method, comprising:
(a) distributing a sample comprising a set of nucleic acids, across a set of partitions comprising at least 20 million partitions;
(b) amplifying the set of nucleic acids within the set of partitions;
(c) in a container, detecting signals corresponding to target nucleic acids of the set of nucleic acids, from multiple partitions of the set of partitions simultaneously, upon scanning a cross-section of the container; and
(d) counting partitions comprising signals detected in (c), wherein the counting does not comprise use of Poisson statistics associated correction factors wherein the set of partitions comprises a set of droplets, wherein the set of droplets are of an emulsion, wherein a given droplet of the set of droplets of the emulsion: (i) is in a continuous phase of the emulsion; and (ii) is surrounded by an immiscible film, wherein the immiscible film is immiscible with the continuous phase and with the given droplet of the set of droplets.
