Question: What is the best way to cut out a face in a photograph with a busy background ?
I'm also looking for SPEED and accuracy.

Also this is for print usage not video.

The ways i'm familiar with are:
1. Hand paint a mask with paintbrush.
2. Use lasso tools to create a selection set
3. Use pen tool
4. Use extract filter

Thanks
