(polytone is required for this to work so technically not vanilla)
also i STRONGLY advise you use this amazing mod /mod/packed-packs as this resourcepack might cause resourcepack errors semi frequently so itd be best to save a preset of your resourcepack selection
(also for the best experience use a resource pack that adds emissive textures via continuity or its own core shaders i highly recommend this one /resourcepacks/emissive+shaders or /resourcepacks/luminous-vanilla)
!polytone

Adds HDR bloom to vanilla minecraft! (polytone)
