I agree about the Hubble Palette. I have never liked the way it’s used to enhance digital images. I am not a fan of Pixinsight software ether.
I have seen to many times, images that are very good, and took time and effort to capture. Spoilt by over processing, and sharpening.
I think most people want a pretty pictuer at the end off the day. But I’d rather see a more natural looking image that has valuable information added.
