Ok magick, thanks for your prompt response, I was going crazy.

What is the -list option to see the methods available for evaluate-sequence?
I can not see anything in -list list that seems to match, and no list item is mentioned in the offical options page. http://imagemagick.org/script/command-l ... e-sequence

Also while 'add' seems to work the methods 'multiply' and 'divide' doesn't though they are accepted!

It is all very very strange.

I am writing this up in
http://www.imagemagick.org/Usage/layers ... e-sequence

median is working.

It will take all the pixels at some location from each image, and sort them by intensity.
It will then select the 'middle' pixel from the sorted list.

NOTE that unlike 'max' or 'min' (whcih is equivelent to compose 'lighten' and 'darken') it will select the whole of the pixel, not just the individual red, green, blue components. that is the resulting image will never contain a new color that was not found in at least one of the images given.

See Lighten and Darken about how it can generate 'mixed' colors.

OK, -evaluate-sequence is working! Thanks a lot to the team and congratulations for a great work!
