ok this is my first tut so bare with me poeple

ok first step is to make you sig and everything
and make sure your text or whateva u want this effect to go on is a rastrized layer not just a text layer



use the settings shown

Now make a new layer(ctr + shft + n)

and make a small gradient like so



and then u should have this



then when you have that hit ctr + g and switch the blending mode to lighten
then move the layer ova the text so u can see the light ova the text like so
(i made mine red so u can see it)



now switch to image ready there should be a little button at the bottom of the tool bar as shown below


now duplicate the layer in the animation window
select the first frame and drag the layer with ur gradient to the left so u cant see it
then select the second and drag the layer with the gradient to the right so u cant see it
and reselect the 1st frame

then click the tween button



and use these settings



(15-20 frames works good doesnt have to be 20)

hit enter and bam your effect is complete.....
