We describe methods applied to the final photometric reductions and calibrations to the standard system of the images collected during the third phase of the Optical Gravitational Lensing Experiment survey - OGLE-III. Astrometric reduction methods are also presented. The OGLE-III data constitute a unique data set covering the Magellanic Clouds, Galactic bulge and Galactic disk fields monitored regularly every clear night since 2001 and being significant extension and continuation of the earlier OGLE observations. With the earlier OGLE-II and OGLE-I photometry some of the observed fields have now 16-year long photometric coverage.

A DESCRIPTION OF QUASAR VARIABILITY MEASURED USING REPEATED SDSS AND POSS IMAGING (2011, methodology): “Koz lowski et al. (2010a; hereafter Koz l10) applied the DRW model to the well-sampled Optical Gravitational Lensing Experiment (OGLE) light curves (Udalski et al. 1997; Udalski et al. 2008) of mid-infraredselected quasars behind the Magellanic Clouds from Koz lowski & Kochanek (2009).”
MODELING THE TIME VARIABILITY OF SDSS STRIPE 82 QUASARS AS A DAMPED RANDOM WALK (2010, methodology): “Koz10 applied the model to the OGLE light curves (Udalski et al. 1997; Udalski et al. 2008) of mid-infrared-selected quasars behind the Magellanic Clouds from Koz lowski & Kochanek (2009).”
QUANTIFYING QUASAR VARIABILITY AS PART OF A GENERAL APPROACH TO CLASSIFYING CONTINUOUSLY VARYING SOURCES (2009, methodology): “By combining these candidates with the OGLE-II and OGLE-III (Udalski et al. 1997, 2008) light curves, we can verify that quasar light curves are well described by a stochastic process based on a much larger sample of objects than used by Kelly et al. (2009) and then explore using this approach to…”
The Galaxy in Context: Structural, Kinematic, and Integrated Properties (2016, methodology): “Large numbers of RR Lyrae stars, identified by the Optical Gravitational Lensing Experiment (OGLE, Udalski et al. 2008) and Vista Variables in the Via Lactea (VVV, Minniti et al. 2010) surveys, were recently used to map out the old metal-poor population in the bulge (Pietrukowicz et al. 2015 and…”

Binary planetary nebulae nuclei towards the Galactic bulge - I. Sample discovery, period distribution, and binary fraction (2009, methodology): “OGLE-III V-band images and magnitudes were unavailable given the provisional calibration of bulge data (Udalski et al. 2008), but for four PNe we have inspected their V-band images (effectively shallow [OIII] images).”

AN ALTERNATIVE APPROACH TO MEASURING REVERBERATION LAGS IN ACTIVE GALACTIC NUCLEI (2010, methodology): “Koz lowski et al. (2010) show how the Kelly et al. (2009) approach can be derived from the SPEAR approach and demonstrated that forecasting is less statistically optimal for parameter estimation than using the complete light curve modeling method of SPEAR, and then applied the process model and the ”
