I discovered, while tinkering aimlessly, that the Effects > Style > Relief effect is very useful for rescuing slightly out-of-focus photos. (But not all.)
I then apply the Effects > Blurs > Surface Blur effect to make the texture look more natural.
It doesn't work in some photos, depending on the lighting. And it works very badly if I apply it to a photo that I've already reduced in size. (I shoot at about 8 mpx which looks best with my Sony DSC-W300.)
It would be really useful if I could adjust the degree to which the Relief effect is applied ("fade" it in Photoshop terms). I'm wondering if this added feature is available through a different plugin.
Discovery was made just in time to correct photos of our singing group, shot by a non-savvy user in the audience with my camera.
