I scanned an old, somewhat degraded photo, The horizontal center (i.e., top to bottom between left/right edges) is faded, getting better towards the left/right edges.
Is there a way to apply a graduated filter so that I can increase make adjustments to the center, fading out towards the right AND the left? That is, the effect normally graduates towards an edge; I want it to be strongest in the center and fade towards both edges.
I think this is either a job for Photoshop, or the Lightroom adjustment brush
Can't you just do two graduated filters?
