Thanks Damien, appreciate it.

HI there Damien!

I'm blending 7 focus stacked macro images in the usual manner (i.e. stack up as layers; Auto-Align Layers; Auto-Blend Layers).

This method works with the simpler images with obvious shapes however there seem to be many areas that are out of focus; i.e. it has selected an area from the wrong layer. 

I have also attempted to Auto-Blend just two layers at a time, so that it has less work to do; then blend the merged layers. However it's no good, there are still areas that are out of focus.

Have you got any ideas or suggestions on how to achieve a smooth finish using the Auto-Blend function?

PS I have 10 images with multiple layers to do process and I might actually cry if you suggest a manual edit.
