Hi John,

thanks for the link! :bigthmb:

Personally, I'd rather use the Overlay Layer for the purpose, for all the reasons described in the article and because I think it gives me more control .... But the possibility of achieving the desired result trying many different ways, is one of the great advantages of Photoshop!!

Take care.
