What does Photoshop's blend channel op do and what is the Gimp equivalent? It is used in Kai's Power Tips & Tricks at http://www.pixelfoundry.com/Tips/KPT1/KPT1.html to produce "K9" near the end. While I'm at it, what does the PS Composite command do? Kai says it takes 3 layers as input. Thanks for your time, Alan
