  Measurements of inclusive isolated-photon and photon+jet production in
proton-proton collisions at $\sqrt{s} =$ 13 TeV are presented. The analysis
uses data collected by the CMS experiment in 2015, corresponding to an
integrated luminosity of 2.26 fb$^{-1}$. The cross section for inclusive
isolated photon production is measured as a function of the photon transverse
energy in a fiducial region. The cross section for photon+jet production is
measured as a function of the photon transverse energy in the same fiducial
region with identical photon requirements and with the highest transverse
momentum jet. All measurements are in agreement with predictions from
next-to-leading-order perturbative QCD.
