when doing a sig you manage to put some sort of light on the tip of something , for instance on the name tina on the *i* how would you make the *.* shine? or seem like its glowing so to speak. hope this makes sense.
ok thanx , lol its from seeing your siggys that made me wonder , i just did one for someone and i so wanted to put the shine on or some stars that would shine but couldnt work out how to do it lol
Also one of the 'assorted brushes' (well two infact) are spiky stars (there are also standard shape star brushes too. You can use these brushes to paint a star and then add a lighting effect to it.
Other things to play with are filter>neon glow and filter>diffuse glow.
Also on artwork (above layers on the right side of the screen), the little icon before the text icon adds effects to a whole layer when you choose 'layer styles'. There are inner and outer glows..some freaky neon ones too, that are fun to play with.
