Bloom HDF is a photo editor for shaping highlight diffusion, bloom, and halation with a restrained photographic look.
Made for Ricoh GR photographers who want the HDF look and highlight diffusion character without changing camera bodies, Bloom HDF helps you bring a softer, more luminous rendering to photos you already shot.
Import JPEG, HEIC, and supported RAW files, preview the effect in real time, and fine-tune the glow with controls for opacity, blur radius, softness, highlight threshold, highlight focus, warmth, and blend mode. Use Before, After, and Mask views to understand exactly how the effect is being applied.
Bloom HDF is designed to stay simple while still giving you meaningful control:
• real-time Before / After / Mask preview
• highlight diffusion tuning with a clean, focused workflow
• blend modes including Screen, Soft Light, Lighten, and Dodge
• JPEG, HEIC, and supported RAW support
• full-resolution JPEG export
• save, share, or export across iPhone, iPad, and Mac
Whether you want a subtler highlight bloom, a warmer halation feel, or a softer HDF-inspired character, Bloom HDF gives you a dedicated workflow for shaping luminous highlights without relying on gimmicky filters.
