Photo Exposure Editor

The exposure editor focuses on correcting image brightness and tonal balance. It accepts a source image and user-specified exposure adjustments measured in stops, optionally refined by gamma control. Exposures are applied in a linear light domain to preserve proportional changes across brightness levels. Output is a new image showing the requested exposure change while maintaining color fidelity and avoiding abrupt clipping.
The processing pipeline uses a simple, deterministic sequence: convert the input to linear light, multiply luminance by 2^(exposure_stops), clamp to [0,1], then apply gamma encoding for display. If auto mode is selected, the system analyzes the image histogram and nudges the exposure to minimize clipping in shadows and highlights, prioritizing midtones.
Who benefits includes photographers, retouchers, catalog publishers, and social media teams needing consistent exposure across assets. The tool provides a focused option for rapid iterations without complex edits, making it ideal for quick proofs, batch adjustments, or standardizing look across a sequence.
Core features include input validation for file formats (JPEG, PNG, TIFF), size limits, and exposure range; color-space handling to reduce color shifts; output formatting choices; and an optional batch mode for processing multiple images. Unique value lies in speed, repeatability, and clear export paths for web or print.
