ON1 HDR 2022 is a professional-grade high dynamic range (HDR) image editing and compositing software designed specifically for macOS. It integrates powerful RAW processing, layer compositing, local adjustments, and filter effects into one package, aiming to help photographers efficiently create natural or artistically rich HDR images. This guide will provide a detailed introduction to its interface, complete workflow, and practical tips.

I. Detailed Explanation of the Core Interface and Workspace

After launching ON1 HDR 2022, you will see a logically clear workspace, mainly divided into the following modules:

Top Menu Bar and Toolbar: Includes file operations, editing tools (crop, brush, gradient, etc.), view controls, and the help menu.
Left Panel – “Browse” and “Presets”: In “Browse” mode, you can navigate folders and select source images; the “Presets” panel offers a large number of one-click effects, categorized into HDR, Looks, Black & White, and more.
Central Viewing Area: Displays the image currently being edited. Tabs at the top allow you to switch between different open images or composite views.
Right Panel – Adjustment Modules: This is the core editing area, typically including from top to bottom:
- HDR Merge Settings: Controls alignment, ghost reduction, and tone mapping modes (Natural, Creative, etc.).
- Basic Adjustments: Exposure, Contrast, Highlights, Shadows, Color Balance, etc.
- Filters: Such as Dynamic Contrast, Color Enhancement, Glow, Tone Curve, etc., which can be stacked and controlled individually.
- Local Adjustments: Use brushes, gradients, and radial filters for local editing.
- Layers: Manage adjustment layers and image layers, with support for blend modes and opacity.
Bottom Panel: Displays the histogram, metadata, and options for managing batch processing and export.

II. Complete Workflow: From Creation to Export

Step 1: Create/Open a Project

Launch HDR Merge: Click the menu bar “File” > “New HDR Photo…” or use the shortcut Cmd + N.
Select Source Images: In the pop-up browser window, navigate to the folder containing the bracketed exposure sequence images. Hold the Cmd key and click to select multiple images with different exposures (typically 3-5 images).
Import Settings: In the right panel, check “Auto-Align Images” (required for handheld shooting) and “Remove Ghosting” (required for scenes with moving objects). Select a color mapping mode, such as “Natural” or “Creative”.
Generate Preview: Click the “Create HDR” button in the bottom right corner, and the software will merge the images and display the preliminary result in the central viewing area.

Step 2: Basic Global Adjustments

In the “Basic” adjustment section of the right panel, use the sliders to fine-tune the overall tone:
- Exposure/Contrast: Determine the overall brightness and darkness of the image.
- Highlights/Shadows: Recover detail in overly bright or dark areas.
- White/Black Levels: Define the brightest and darkest points of the image.
In the “Color” section, adjust saturation and vibrance, or use the white balance tool to correct color temperature.

Step 3: Apply and Stack Filters

Click the “Add Filter” button in the right panel (or drag from the presets panel) to add effects to the image.
Common filters include:
- Dynamic Contrast: Enhance local contrast without causing halos.
- Color Enhancer: Intelligently boost color saturation and brightness.
- Tone Curve: Achieve precise contrast and color control.
Each added filter will appear in the list; click its eye icon to toggle the effect on or off, drag to reorder, and double-click to rename.

Step 4: Local Adjustments

In the right panel, switch to the “Local Adjustments” tab.
Select an adjustment tool:
- Brush tool (shortcut B): Freely paint mask areas.
- Gradient filter (shortcut G): Create linear gradient masks.
- Radial filter (shortcut R): Create circular radial gradient masks.
In the tool options bar, set the brush size, feathering, and flow. Within the mask area, you can individually adjust exposure, color, and other parameters to achieve local brightening, darkening, or color grading.

Step 5: Use Layers for Compositing and Retouching

Switch to the “Layers” panel. The initial merged result serves as the background layer.
Click the “Add New Layer” button at the bottom of the panel to choose from:
- Blank layer: For drawing or pasting elements.
- Image layer: Import other images for compositing.
- Adjustment layer: Apply non-destructive adjustments that only affect layers below.
Use layer masks and blend modes (such as Overlay, Soft Light) to blend multiple images or effects.

Step 6: Final Export

After completing all edits, click the “Export” button on the right side of the top toolbar, or use the menu “File” > “Export” (shortcut Cmd + E).
In the export dialog, configure:
- Export location: Choose the destination folder.
- File format and quality: Such as JPEG (set quality), TIFF, or PSD.
- Image size: Adjust dimensions and resolution.
- Output sharpening: Optimize for screen or print.
Click the “Export” button to complete the process.

III. Advanced Tips for Common Features

Quick before/after comparison: Press the shortcut (backslash) to quickly switch between the original and edited image.
Non-destructive editing workflow: Use filters and adjustment layers as much as possible rather than directly modifying the background layer. All filters and local adjustments can be turned off, modified, or deleted at any time.
Boost efficiency with presets: In the “Presets” panel, right-click a preset you like and select “Apply to new layer” to easily stack effects and control intensity.
Precise mask control: When painting local adjustment masks, hold the Option key to switch to “Erase” mode. Use the bracket keys [ or ] to quickly adjust brush size.
Batch processing: In “Browse” mode, select multiple images, right-click and choose “Batch process…” to apply the same HDR merge settings and presets for efficient output.

IV. Common Issues and Solutions

Issue: Ghosting (double images) appears in the merged image
- Solution: In the initial merge settings, increase the strength level of “Deghosting,” or try different detection modes (such as “People,” “Vehicles”). For complex scenes, you can manually brush the areas in the “Deghosting” tool.
Issue: HDR effect looks unnatural or overly exaggerated
- Solution: Try selecting the “Natural” tone mapping mode when merging. In post-processing, reduce the intensity of the “Dynamic Contrast” slider under “Basic” adjustments, and check whether highlights/shadows are overly compressed, causing the image to look flat.
Issue: Software runs slowly or lags
- Solution: Check the menu bar “ON1 HDR 2022” > “Preferences” > “Performance” and make sure GPU acceleration is enabled (if your graphics card supports it). Try increasing the cache size, and close unnecessary background applications when editing large images.
Issue: Local adjustment brush responds slowly or imprecisely
- Solution: In the brush tool options, lower the “Flow” and “Density” values for smoother buildup. Make sure “Auto Mask” is not accidentally enabled (unless needed). Using a graphics tablet provides the best control experience.
