@gab1one Thanks for the flow idea. I am stuck because at quite a few places, there is quite a bit of confusion regarding the pixel types. I openend a new thread for that and will come back, once I got that: List of Pixel types (e.g. for Image Converter node)
Additionally I would need to know: What does Compose Image do? Is it multiplying the pixel values or adding them up? How does it handle different pixel types? (…and where is that documented if it already is?)
