Hi Nik,

It was a different focal length and I couldnt get the blues out at all for some reason, still learning remember it's the L-Extreme and an OSC

OK sorry -
so the L-Extreme filter is allowing the Blue light to enter

but the One Shot Color has a Bayer Matrix which
is only picking it up on 1 pixel out of 4.

Looking great! Super tight and I actually don't mind the colour pallet... I'm interested how did you created the synth green channel in APP tho?

Hi Dave, in APP when you stack you have the option of selecting mono HO111 under the bayer matrix and use the final result as the synthetic sulphur/green channel, then you obviously play around in combination setting and adjust to suit
this video and the next one helps explain

I changed up the processing using just HOO and a smidge of synthetic sulphur and this is the final result.

It looks great Nik
The rich orange, blue and violet really works.

Best
