I’ve just posted a tutorial describing my suggested workflow for ALCE (Advanced Local Contrast Enhancer for Photoshop) on equirectangular images, the ones used to build those immersive, 360° virtual tours (a couple of useful recommendations to avoid issues in the edges, that must blend seamlessly). You can read it here, in the RBG blog (Roberto Bigano Group), where I use to post from time to time.
