In Jupiter, it is very important to use filters because they reproduce the aspect of the planet according to the wavelength. In the near-infrared, radiation emerges from an atmospheric layer deeper than visible clouds, and many details appear more defined and contrasted. The ultraviolet probes a higher altitude, as do the methane absorption bands (the most used at 889 nanometers), in which the planet is very dark, but the higher cloud layers, above which gas absorption is less, appear decidedly bright (the EZ, the Great Red Spot, some anticyclonic ovals).
