Reworking some old data


MY processing skills with LRGB are definitely improving in fits and starts, so I have gone back to  some of the old data and reworked it. Originally, the main problem was lack of colour.

Now, the processing is:
Register, align and stack as separate channels in DSS
Stretch (levels and curves) each channel in PS
Combine the R,G and B, adjust using Histogram to give same pseudo white point
Saturate
Add the Luminance channel, use Luminosity as blend mode.
IF necessary, try using HLVG
Import the LRGB into Lightroom and improve
