The parameters of the Drop Shadow effect in Photoshop are blend mode, colour, opacity, distance, spread, and size.
In Illustrator, they are colour, opacity, x-offset, y-offset, and blur.
I am struggling to recreate my Photoshop shadow effect in Illustrator. I understand the relationship between distance in Photoshop and x,y-offsets in Illustrator. Blur is what I am stuck at. Is there a metric/formula I can use to copy the shadow attributes from Photoshop to Illustrator?
