Question about airbrush - doesn't seem to work

[geo]

Hi,
With CS2, having the airbrush option clicked or not, I get the same effect. Nothing changes. What's going on?
I remember in earlier version you had something like a spray gun and the effect was much different than that of a brush.
Any comments?
thanks.

Set the "Flow" option to something other than 100%.

reducing flow is like reducing opacity. Still don't get the spray effect

Reduce the opacity, then hold the airbrush for a few seconds on the same spot. You'll notice that the amount of color laid down does increase. That's the difference with the regular brush, it will not spray your brush around. You should look in the brush palette for scattering settings to get this effect.
