Depth channel extraction
The process of isolating spatial distance information from an image to create a grayscale representation where pixel luminance corresponds to the distance from the camera lens.
Applications
- lens-blur: Simulating realistic bokeh by applying depth-dependent convolution.
- 3d-photo-adjustments: Executing localized color grading, lighting, and atmospheric effects based on spatial planes.
- Compositing: Creating seamless integration between foreground and background elements using depth-aware masking.
Implementation & Resources
- Photoshop Depth Map: Utilizing grayscale maps for precise, non-destructive manipulation of photographic depth.
- Tool Integration: Leveraging depth data within camera-raw and lightroom to drive advanced blur algorithms.
