Okay, I had to figure out how this works in Paintshop pro, but let's see: I overdid it a little to see the effect. First one is done with the red/green/blue effect., enhancing blue, the second one with the Channel mixer, god knows what the difference is. You see quite a difference in effect, the first staying much more close to the sepia effect and is much more subtile, while the second one gives a blue-greenish effect.. Some shadows/fades don't work out well (see cockpit) I'll have to try and correct this.
