post #30
thanks a lot Joe.
please remember all that i did was make it into a action :) joe done all the hard work

[COLOR="Red"]Joe has pointed out to me that after both times of the diffuse being used you should reduce the opacity to exactly 50% [/COLOR] ( i have altered the wording in the action to accomodate this)

[COLOR="RoyalBlue"]After some experimenting i have found on portraits that it is best to use something like neat image first then run the action [/COLOR]
