Problem
Depth blur is applied uniformly and removes useful separation between multiple important objects.
Solution
Root Cause / Diagnostic:
Applying a flat, single-radius blur filter across an entire background or multi-subject composition flattens three-dimensional depth cues. When midground context elements are blurred identically to distant background elements, spatial narrative coherence is destroyed.
Actionable Fix:
1. Construct a depth map gradient (Z-depth pass) ranging from pure black (in-focus foreground/midground) to pure white (distant background).
2. Drive a Lens Blur filter using the custom depth map channel, setting focal distance to keep critical midground objects sharp while progressively softening distant layers.
3. Review the composited scene to ensure natural spatial gradation from sharp foreground to soft horizon.
Pro Tip:
Utilize custom gradient-based depth maps to apply progressive blur; natural z-axis depth falloff preserves storytelling props in the midground while softening distant clutter.
