Pros & Cons

👍 Pros

  • Effectively creates a soft "glow effect" in images, which can be desirable for artistic and cinematic looks
  • Provides a slight reduction in contrast, contributing to a smoother, less harsh overall image appearance

👎 Cons

  • Applying a diffusion effect directly in-camera means it cannot be removed or significantly altered in post-production if overdone
  • Specific information on light loss (f-stop reduction) is not provided, which could impact exposure settings
