Problem
Thumbnail has inconsistent local contrast because different assets were processed with different enhancement settings.
Solution
Root Cause / Diagnostic:
Combining multiple image assets sourced from different cameras or stock libraries—each with its own disparate clarity, contrast, and black-level processing—shatters compositional unity. When one cut-out element is hyper-contrasted while another is milky and washed out, the composite looks like a disjointed collage of mismatched stickers.
Actionable Fix:
1. Apply a unified adjustment layer (Curves or Levels) across the entire composite canvas to harmonize black points and white points.
2. Standardize local contrast enhancement (Clarity / Texture) across all individual asset layers before global grading.
3. Inspect composite balance in grayscale mode to confirm that all scene elements share a coherent dynamic range and lighting logic.
Pro Tip:
A master global grading layer tied across all assets unifies disparate photo cutouts into a single convincing, cohesive reality.
