Hello @AngelaDMerkel, Sure, just load them, then use In python (untested): bands = [pyvips.Image.new_from_file(f"{band}.png") for band in ["r", "g", "b"]]
rgb = bands[0].bandjoin(bands[1:]).copy(interpretation="srgb") |

I am looking for a way to import three different grayscale raws as each one R, G, and B colour channel. My use case is digitising negative film using alternating outputs of red, green and blue LEDs to produce a more veracious rendition of the dyes. I am trying to emulate the way older film scanners worked.
Is what I am considering possible in vips?
