At the top of that same thread is an image with an OSC with a duoband filter.
So I guess the point is, there is no "natural". We tend to define natural as mimicking the human eye, which a DSLR would be the closest, but it's still not natural or a universal law. Human eyes are incredibly insensitive to a broad spectrum, so this is where the artistic license comes into it that you mention.
If you have a camera that can capture more hydrogen, then the centre becomes less blue and more red (not as red as the edges) because there's not only Oxygen there, but also a lot of Hydrogen. You can process that away by focussing on the Oxygen. There's no right or wrong  |
Hi Adam,
Thanks for that.
It wasn't really my intention to get caught up in discussion about M8 colours. I think that's why I put the word Natural in commas as it was a variation away from false colours.
Always good see your posts.
Chris.
