This SHOULD be really simple, but I can't seem to achieve it effectively with Inner Glow. The effect is so commonly used; nearly every logo here features the effect of a subtle gradient effecting a slightly darkened edge to the base background colour.
I can't seem to get an effective gradient between my dark outer tone and base inner tone, instead stuck with a "banding" effect in Ps. I've yet to try in Ai, but any tips to creating it there would be sincerely appreciated too!
Many thanks in advance!
