Preserved Topic: A problem, (I think)

Hello all, new to posting, long time lurker. I have a small problem, well at least i think it is maybe you can help.
Recently i was trying a tut, not sure which but everytime i applied the lighting effect filter on the alpha channel I got some nasty jaggies.



In the above pic I have two airbrush dots at 65. One on the left is from the RGB channel, one on the right is from the Alpha Channel. The one from the RGB channel looks nice and smooth. The 2nd does not, looks kinda rounded. I was wondering if this was normal or if i have a setting messed up somewhere in the alpha channel.

Thanks for the time and help .

What is looks like is that the alpha channel had a certain circular area selected that you filled with a radial gradient. Make a new alpha channel and do a radial gradient from the center out to wherever you want (without previosly making a selection in the channel) and see if that helps...

Both dots are from one click of the mouse using the airbrush, one on the rgb channel, other on alpha channel..

Hmmm. That's wierd. I just tried it, and got exactly the same thing in both the RGB and the alpha. Are you sure there wasn't a selection when you tried the brush in the alpha? That defined edge looks like the paint was constrained by a selection.

Sorry - can't help much since I can't reproduce the problem. I can't think of any "settings" you would have wrong. If you used the exact same brush with the exact same foreground color, no settings should have changed. Did you create the new alpha by clicking on the icon at the bottom of the channels palette? Any chance you might have command/control clicked on one of the composite channels (which loads them as a selection) before brushing on the alpha?

I used the brush tool, not the airbrush. Want to see if that makes any difference?

Tried the brush , same thing happened.... , odd.... I guess i'll keep playing around with it.. Thanks for the help

Well i reinstalled Photoshop and all seems to be ok now, must have been some sort of color setting that was messed with. That brings me to another question. I sort of curious of what kind of color settings you all use so i can see what i could tweak to get better colors.

Thanks
