I had some old createx opaque black lying around and was trying to do some shadings on a small (A4) size b&w portret. I reduced it down with water and it sprays very well, thin lines, little dots but when i try shading it always gets immediatly to dark. I know i am using an opaque color (covers far more then a transparent). I can get it to spray more transparent by reducing even more untill its starts to behave as just dirty water and spraying less paint and more air. Now when i get in to close i just pull a line and when i move to far out it sprays more transparent but then my spray patern is to big for the area i am working in. I am still new to airbrushing so what am i doing wrong, is it me (probably ), the paint (mix in white) or something els? All help is welcome. Ps.: i use a iwata hpc plus with 0.3 needle.
