CIELAB colour space
I have recently discovered the joys of processing in the CIELAB (L*a*b*) colour space. I have mainly been using it for tweaking of colour and colour intensity, but I have also developed some more specific techniques that rely on it, e.g. for fixing coloured star haloes and transplanting RGB stars into a narrowband image.
Jay GaBany included LAB manipulation as one of the (ten?) techniques for colour enhancement in his AAIC 2013 talk. He mentions it again in the "Lessons from the Masters" book and the section by Adam Block in the same book includes a couple of pages on using LAB in Photoshop for adjusting galaxy colour. Apart from this I haven't seen it mentioned much in the astro context.
Is anybody else using LAB in their processing?
Cheers,
Rick.
