I will review the method of exoplanet atmospheric retrieval, focusing on transmission spectra. I will discuss in great detail a key practical limitation known as the normalisation degeneracy, examining it in three different regimes of atmospheric retrieval (HST, JWST, ground-based high-resolution). Finally, I will review an analysis of all 38 existing Hubble Space Telescope-WFC3 near-infrared transmission spectra to a Bayesian hierarchy of retrievals.
