GIMP Layers – Mode & Opacity

The next part of this tutorial covers Mode & Opacity.  These two options combine to provide a decent amount of simple, yet powerful layer manipulation in GIMP.


Each of the many modes provide a different way to display the layer, and the opacity determines how transparent/visable the layer is.  Below is a sampling of just a handful of the different modes and how they effect a layer.



Normal is the default mode for all layers.  The above shows the yellow oval with a 50% opacity.



Again showed at 50% opacity, dissolve essentially dissolves the layer pixel by pixel with nearly all of the layer showing at 100% opacity, and nearly nothing showing as the opacity approaches 0%.



Multiply makes the layer feel almost like a lens filter and gives the effect of mixing colors.



Difference shows the color remaining after removing the layer’s color from the background.

    thanks for this tutorial. Those are good explanations and examples. I also recommend the screen mode for adding some reflection, but I cannot explain what the screen mode actually does to the layer.
