<div>Interstellar dust is a product of star formation that
is ubiquitous across star-forming galaxies during cosmic
noon, and absorbs and scatters light within the galaxies.
Correcting for dust is necessary when inferring several
galaxy properties, including star-formation rate and the
age of stellar populations. Hydrogen recombination lines
are the most common tool for determining reddening and
star-formation rates in nebular regions within galaxies.
The advent of JWST has enabled new observations of Paschen
emission from galaxies at z~2, which is less affected by
dust than Balmer emission. For our analysis, we obtain
measurements of Balmer and Paschen emission for a sample
of 83 galaxies using ground- and space-based observations
from MOSFIRE and NIRCam/grism. We compare the nebular
reddenings as probed by the Balmer and Paschen emission
and find that, once observational effects are accounted
for, using Paschen emission can reveal star formation in
regions that are optically thick to the Balmer emission
alone.</div>
