In Photoshop, the Opacity setting controls the opacity of the paint – are you painting with an opaque metallic paint or a transparent varnish. The Flow setting controls the speed at which paint is laid down – are you pressing the nozzle of the can of spray paint just a little or all the way down?

    I have used tutorials of a certain Photoshop lecturer and he always used ‘flow’ but never explained why. Thank you for this – enormously helpful and clear.

    I’d love a clear definition of the difference when applied to layers rather than brushes. I know that I can use flow to reduce the layer contents while leaving any layer styles intact. I am just not sure why it works that way.
