Blending/merging N images with more weight for brighter areas in ImageMagick

[sm535]

Hello All,

Need to merge/blend two images in ImageMagick such that brighter parts of each image will get more weight towards the final blended result. For example, if there are two images with a light spot in position A and B respectively, the darker parts of the second image in the position A will be given, say 10%, weight while the brighter part from the second image would get 90% of the weight during final merging. I have tried the following in ImageMagick without success:

convert -luminize
convert -evaluate-sequence mean
composite -dissolve P

Create a mask for each image with it lighter where you want to emphasize one image and darker where you want to emphasize the other image. The do a 3 image composite with the mask as the third image. See https://www.imagemagick.org/Usage/compose/#compose
