Aurora HDR 2018 is an HDR (High Dynamic Range) image processing software designed specifically for macOS. It was jointly developed by renowned photographer Trey Ratcliff and Skylum, and has become one of the preferred tools for professional photographers and advanced enthusiasts for HDR compositing and editing, thanks to its outstanding tone mapping algorithms, intuitive workflow, and powerful detail control capabilities. This guide will provide an in-depth analysis of its core interface, complete operation workflow, and advanced tips.
1. Core Interface and Workspace Detailed Explanation
After launching Aurora HDR 2018, users are presented with a clearly laid out working environment with well-defined functional zones. The main interface is primarily divided into the following core areas:
- Top Menu Bar and Toolbar: Includes standard menus such as File, Edit, and View. Below it is a toolbar of commonly used tool icons, such as “Crop,” “Transform,” “Spot Repair,” etc., providing quick access.
- Left Panel – “Library/Presets” Area: Displays the “Presets” panel by default. This offers a large number of one-click presets designed by professional photographers, categorized into “Basic,” “Artistic,” “Color,” and more, serving as a starting point for quick stylization.
- Central Area – Image Preview and Editing Area: This is the core workspace, displaying the currently opened image in a tabbed format. It offers multiple view modes, such as the “Original/Processed” comparison view (shortcut
Y). - Right Panel – Core Adjustment Panel: This is the core area for fine-tuning, containing a series of vertically arranged adjustment modules:
- HDR Enhancement: Controls the intensity, detail, and color saturation of HDR effects.
- Color Filter: Simulates the effect of traditional colored glass filters.
- Color: Adjusts hue, saturation, and lightness (HSL).
- Toning: Controls highlights, shadows, white levels, and black levels.
- Detail Enhancement: Performs sharpening and noise reduction.
- Tone Curve: Provides RGB and channel curve adjustments.
- Transform: Corrects perspective and lens distortion.
- Gradient Filter: Adds gradient and radial filters for local adjustments.
- Bottom Area – Layers and History: Displays all adjustment layers of the current image and supports blend modes and opacity adjustments. The History panel allows users to revert to any editing step.
II. Complete Workflow: From Import to Export
Step 1: Create or Open a Project
Method 1: Create a New HDR Project (Merge Multiple Bracketed Exposure Photos)
- Click the menu bar “File” > “New HDR Project” or use the shortcut
Command + N. - In the file picker that pops up, hold down the
Commandkey to select multiple images shot in the same scene (usually 3-7 photos) with different exposures (such as underexposed, normal, and overexposed). - Click “Open,” and the software will automatically align the images (if there is movement) and merge them into a single 32-bit HDR base image.
- In the merge dialog box, you can check options such as “Remove Ghosting” (to eliminate ghosting caused by moving objects) and “Chromatic Aberration Correction.”
Method 2: Open a single image for editing (HDR look simulation)
Click the menu bar “File” > “Open” or use the shortcut Command + O to select a JPEG, TIFF, or RAW format image. The powerful engine of Aurora HDR 2018 can apply HDR enhancement effects to a single image.
Step 2: Basic Adjustments and Stylization
- Apply a preset (quick start): In the “Presets” panel on the left, click the preview thumbnails of presets in different categories. A single click applies them. This is a quick way to achieve an ideal base tone.
- Core HDR adjustments: In the right panel, first adjust the “HDR Enhance” slider.
- HDR Enhance: Controls the intensity of the overall HDR effect. It is recommended to adjust it moderately to avoid a “plastic look.”
- Smart Tone: The software intelligently balances the image’s color tones, usually serving as a basis for fine-tuning.
- Detail Enhancement: Improve the clarity of textures and edges.
- Tone and Color Fine-Tuning: Switch to the “Tone” panel and adjust “Highlights,” “Shadows,” “White Point,” and “Black Point” to recover more detail. In the “Color” panel, use the HSL sliders to adjust specific colors.
Step 3: Local Adjustments and Retouching
After global adjustments, you usually need to strengthen or weaken specific areas.
- Using Masks: Click the “Mask” icon at the top of the right panel (or press the
Fkey), and choose “Graduated Mask” or “Radial Mask.”- Drag on the image to create a mask area.
- In the slider panel that appears, you can independently adjust the exposure, contrast, saturation, and more for that area.
- Use
Command + Zto undo an action, and use theDeletekey to remove the selected mask control point.
- Using Layers for Local Adjustments: In the Layers panel at the bottom, click the “Add New Adjustment Layer” icon. You can use the “Brush Tool” to paint on the layer mask, limiting the area where the adjustment takes effect.
- Detail and Noise Reduction: Zoom the image to 100%, and in the “Detail Enhancement” panel, carefully adjust the “Sharpening” and “Noise Reduction” sliders to strike a balance between clarity and image cleanliness.
