Abstract: Recent years have seen an improvement of photometric precision with ground-based observatories routinely achieving a relative precision at the sub-mmag level. With optimized instrumentation and observing strategies, as well as ample time resources, ground-based 1m-class facilities are important players in a wide range of fields. I here summarize the main instrumental and observational strategies conductive to obtaining high-precision ground-based photometry, and review data analysis methods to account for instrumental correlated noise. Finally, I review the main applications of high-precision photometry related to the search for, and characterization of, extrasolar planets.
