My most frequently used tool settings from Paint Tool SAI
[ UPDATED LAST : 16/11/12 ]
° Marker - I use Marker for line art. Because whilst having a
soft appearance it has a sharper edge than say Water.
° Pen - I use pen for sketches and flat colour. Just so I can
use the really sharp edge to get a precise sketch or colour in
all the nooks and crannies.
° Water - I use Water occasionally for shading and such.
I don't use it too often though.
° Blur - Do I really need to explain? （*´▽｀*）
