Very cool Bert. I've been monitoring your progress with your new set up from the shadows. With the set up tuned, you can now stop the tinkering and get on with some mega imaging projects. I like what you've produced but feel you need to get more from the midtones. A DDP stretch is great for seeing what's in the data but doesn't present itself well aesthetically. There is plenty of detail to extract as one could expect with a 3nm filter. I've attached a rough and dirty rendition as a comparison.

Keen to see more of your work.
