ON1 HDR 2021.5 is a professional-grade high dynamic range (HDR) image processing and compositing software designed specifically for macOS. It goes beyond simple exposure merging, integrating powerful RAW processing, layer editing, local adjustments, and creative filter features to provide users with an all-in-one workflow from HDR creation to final retouching. This guide will walk you through its interface, complete workflow, and practical tips in detail.

I. Core Interface and Workspace Overview

After launching ON1 HDR 2021.5, you will be presented with a logically organized, modular workspace, primarily divided into the following key areas:

1. Top Menu Bar and Toolbar: Includes standard menus such as File, Edit, and View. The toolbar below provides mode-switching buttons like “Browse,” “Edit,” and “Effects,” as well as common tools such as Hand, Zoom, and Crop.
2. Left Panel – “Browse” Module: When in “Browse” mode, this area displays folder directories, favorites, and photo filtering options for quickly locating and managing original images.
3. Central Viewing Area: The core area for image display. In different modes, it can show a single photo, a stack of multiple bracketed exposure photos, or the final edited result. It supports multiple tabs for opening several images simultaneously.
4. Right Panel – Dynamic Adjustment Panel: This is the core area for function control. The panel content changes dynamically with the currently active tool or module (such as “HDR”, “Develop”, “Effects”, “Layers”), and includes all parameter sliders, presets, and adjustment options.
5. Bottom Panel: Typically displays the filmstrip, used to show all photos in the current folder or the sequence of source images participating in HDR merging, making it easy for users to select and compare.

II. Complete Workflow: From Project Creation to Export

The following workflow demonstrates the complete path for creating an HDR photo and completing retouching using ON1 HDR 2021.5.

1. Launch and Import Source Images

Steps:

1. Launch the software; it enters “Browse” mode by default.
2. In the left panel, navigate to the folder containing the bracketed exposure sequence images.
3. In the bottom filmstrip, hold the Command key and click to select multiple exposure photos to merge (usually 3-5).
4. Click the “HDR” button in the toolbar, or use the shortcut Ctrl+H, to enter the HDR merge module.

2. HDR Merge and Preprocessing

Steps:

1. After entering the “HDR” module, the central view area will display a preview after automatic alignment and preprocessing.
2. In the “HDR” tab of the right panel, the key settings are as follows:
   • “Remove Ghosting”: Handles ghosting caused by moving objects (such as leaves or people). Select an appropriate mode (such as “Auto” or specify a reference image).
   • “Color Calibration”: Corrects color casts that may result from merging.
   • “Reduce Noise” and “Remove Chromatic Aberration”: Recommended to check these for basic optimization during the initial merge stage.
3. After adjusting, click the “Apply” button at the bottom of the panel. The software will generate a 32-bit HDR initial file and automatically switch to “Edit” mode for further adjustments.

3. Make Global Adjustments in “Edit” Mode

“Edit” mode is the core adjustment area, with the right-side panel containing multiple tabs.

Steps:

1. “Develop” tab: Perform basic tone and color adjustments.
   • Use the “Exposure,” “Highlights,” “Shadows,” “Whites,” and “Blacks” sliders to fine-tune the dynamic range.
   • Adjust sliders such as “Clarity” and “Vibrance” to enhance image quality.
2. “Masking” tab: Apply local adjustments.
   • Select the “Graduated Filter” or “Radial Filter” tool and drag on the image to create an adjustment area.
   • In the control panel that appears, adjust parameters such as exposure and contrast, affecting only the masked area.

4. Add Creative Effects and Local Retouching

Steps:

1. Click the “Effects” button in the toolbar, or use the shortcut Ctrl+3, to enter the Effects module.
2. In the “Effects” library on the right panel, you can browse and click to apply various presets (such as “Black & White,” “Color Tone,” “Texture,” and “Glow”).
3. After applying an effect, use the “Opacity” slider at the top of the panel to control the effect intensity.
4. For more complex compositing, click the “Layers” button (shortcut Ctrl+4) to use brush tools, masks, and multiple layers for selective editing.

5. Final Output and Export

Steps:

1. After completing all edits, click “File” > “Export” in the top menu bar, or use the shortcut Command+Shift+E.
2. In the export dialog that appears, configure:
   • Export Location: Choose the destination folder.
   • File Settings: Select the format (e.g., JPEG, TIFF), quality, and color space (sRGB is suitable for web).
   • Image Size: Adjust the output dimensions and resolution.
3. Click the “Export” button to generate the final image file.
