Antialias of pictures?

Dear Sir,

I know that Mathematica is not designed specifically to deal with pictures,
i.e. Mathematica is not a competitive software against PhotoShop and so on.

But when I Export[] the output of Plot3D[] to be a GIF picture, even I
assign a high-valued PlotPoints (i.e. 400), the curves in the picture still
have a lot of small aliases.

I mean, because of the so-called 'anti-alias' problem when talk about
picture-handling, the curves in the picture have a correct form but NOT
enough especially for the publushing or Web purpose.

I can use PhotoShop to antialias all pictures exported by Mathematica,
but it is trivial. So I want to ask whether Mathematica can export
GIF pictures?

Thank you very much for any advice!
