Tilt Photo Editor

The tool provides a non-destructive tilt-shift editing workflow for raster images. It is designed for photographers, designers, and social media teams who want controlled perspective and depth simulation without modifying the source file. Use cases include portrait and product shots, street photography, and practice scenarios where consistent tilt results are needed across multiple images. The system accepts common formats (JPEG, PNG) and outputs a new edited file while preserving the source. Core Logic & Features: Required inputs are an image, a tilt angle in degrees, and a focus-band width. Optional/advanced controls include outside blur strength, vignette, and export presets for common resolutions. Core capabilities include applying a tilt transformation to the image plane, defining a sharp focus band, producing a gradient blur outside the band, and exporting a non-destructive result. The pipeline is deterministic, enabling repeatable edits, and supports multiple output formats to fit publishing workflows. Inputs & Outputs: Inputs include image_file (JPEG/PNG) with a sample value such as sunset.jpg; tilt_degrees in range [-45, 45]; focus_band_fraction in [0.1, 0.8]; output_format (JPEG/PNG) and crop_to_content (boolean). Outputs include output_file and optional preview image; metadata preserved; blur map generated for review; resolution and color space are preserved unless explicitly scaled. Validation ensures numeric ranges and file size are within practical limits. Algorithms & Calculations: Tilt is realized by a rotation of the image plane around its center combined with a defined focus band. Blur outside the band is applied via Gaussian blur with a radius determined by distance from the band; edge handling uses anti-aliasing for smooth transitions. The algorithm operates in the input color space and exports to the selected format while preserving color integrity and tonal range. Error & Edge Cases: Invalid image format or corrupted input yields a domain error; tilt_angle outside [-45, 45] is clamped; focus_band_fraction outside range defaults to 0.25. Large files may trigger memory constraints and will be downscaled or rejected. External data unavailability is treated as a hard failure with no UI prompts. Industry/Region & Localization: Angles are in degrees; color space is sRGB by default; supported deliverables are JPEG and PNG; no region-specific tax or currency handling; date or locale data do not apply. Assumptions & Exclusions: The tool performs 2D tilt simulation, not a true 3D depth map or real optical tilt. Edits are non-destructive, producing a new file while preserving the original. Batch processing or plugin integrations are out of scope. UI layout and styling details are not covered here.
