Description

- Super luminance created from stack of R, G, B and L. This gave a luminance with higher SNR.

Then super luminance and pseudo luminance from RGB have been merged together (70%-30%).

- Lens opened at f/2.8.

- This looks less sharp than the RGB only version :

RGB only version

Is shooting L with Samyang 135 worth or not ? Still an open question for me.
