ON1 Effects 2020 is a powerful professional-grade photo effects and filter application that can run as a standalone app or seamlessly integrate as a plugin into Adobe Lightroom or Photoshop. It integrates a vast number of presets, filters, textures, and tools, designed to provide photographers with an all-in-one, non-destructive creative photo editing solution.

I. Detailed Explanation of the Core Interface and Workspace

After launching ON1 Effects 2020, you will see a main interface with a clear layout and well-defined functional areas. The entire workspace is mainly divided into the following core areas:

Top Menu Bar and Toolbar: Contains standard menus such as File, Edit, and View, as well as quick-access tools like Crop, Transform, Brush, and Graduated Filter.
Left Panel – Presets and Filters Browser: This is the starting point for applying effects. It displays all built-in and user-created preset libraries (such as Portrait, Black & White, Cinematic, etc.) in a tree structure and thumbnail form, along with independent filter categories (such as Dynamic Contrast, Color Enhancer, Lens Blur, etc.).
Central Area – Image Preview and Editing Canvas: Displays the image currently being edited. Above it are view mode toggles (such as Single View, Before/After View, Split View), zoom controls, and a navigator.
Right Panel – Effects Stack & Properties Adjustment Area: This is the core editing area.
- Effects Stack: Displays all added filters and adjustments in the form of a layer stack. Each filter can be individually toggled on/off, reordered, masked, or used to create local adjustments.
- Properties Panel: When a filter in the stack is selected, all adjustable parameter sliders for that filter (such as exposure, contrast, color, etc.) will be displayed here for fine-grained control.
Bottom Area – History & Photo Browser: Displays editing history steps for quick undo. In browse mode, thumbnails of photos in the folder will be displayed here.

II. Complete Workflow: From Opening to Exporting

Step 1: Create/Open a Project

Method 1 (Standalone Use): After launching the software, click the menu bar File > Open, or use the shortcut Command + O, to select one or more photos from your Mac. You can also drag and drop photos directly into the central preview area of the software.

Method 2 (As a Plugin): In Lightroom or Photoshop, invoke ON1 Effects via the “Filters” or “Plugins” menu, and the currently edited photo will be loaded automatically.

Step 2: Apply and Adjust Effects

Browse and apply presets: In the left panel, click any category of presets (such as “Classic Black & White”), and the central preview image will display the effect in real time. Double-click a preset thumbnail or drag it onto the photo to apply it.
Add independent filters: Under the “Filters” category in the left panel, find options such as “Color Enhancement” and “Tone Curve,” and likewise add them to the “Effect Stack” on the right by double-clicking or dragging.
Adjust filter parameters: In the “Effect Stack” on the right, click an added filter, then in the “Properties” panel drag the sliders for various parameters to make personalized adjustments.
Manage the effect stack: You can drag to adjust the order of filters, click the eye icon in front of a filter to toggle its effect on or off, and right-click a filter to duplicate, delete, or create a mask.

Step 3: Make local adjustments (masks and brushes)

This is the key to achieving creative control.

Select a filter in the “Effect Stack.”
Click the “Add Mask” button below the stack (or use the shortcut Command + M) to create a mask for that filter.
Select the “Brush Tool” from the top toolbar (shortcut B). In the “Properties” panel on the right, set the brush size, feathering, flow, and more.
Paint on the image: the white brush adds a blur effect, while the black brush (hold the Option key to switch) erases the effect. You can use the “Gradual Blur” or “Radial Blur” tools to create smooth transitions.

Step 4: Final Photo Export

Once editing is complete, click the “Apply” button in the upper right corner of the interface (if used as a plug-in, click “Done” to return to the host software).

To export as a standalone file:

Click the menu bar File > Export or use the shortcut Command + Shift + E.
In the export dialog that appears, set:
- File format: JPEG, TIFF, PNG, etc.
- Quality and size: Adjust JPEG quality, resolution, and output dimensions.
- Output folder: Specify the save location.
Click the “Export” button to complete the process.

III. Advanced Tips for Common Features

Combine presets to create unique styles: Don’t limit yourself to a single preset. You can apply multiple presets or filters in sequence and blend the effects by adjusting the opacity of each (set in the effects stack).
Make good use of the “Auto Mask” feature: When using brush tools for local adjustments, check “Auto Mask” in the properties panel, and the software will try to detect color edges to help you paint more precisely—especially effective when dealing with hair or the edges of complex objects.
Use the “Control Point” for targeted color and light adjustments: In the properties panel of filters such as “Color Enhancer” or “Dynamic Contrast,” use the “Control Point” tool to click and drag on specific areas of the image to intelligently adjust only the pixels of similar color or brightness in that region.
Create and manage your own preset library: Once you have adjusted a set of parameters you are satisfied with, click the “Save Preset” button at the top of the effects stack, name it, and categorize it into a custom folder for easy one-click access in the future.
Non-destructive editing workflow: All operations are saved in the effects stack, allowing you to go back and modify any step at any time. Before exporting, it is recommended to save as an .onphoto project file via the menu bar File > Save to preserve all editing layers.

IV. Common Issues and Solutions

Q1: The software runs slowly or lags?

Solution:

Check and ensure your Mac meets the minimum system requirements, especially memory (RAM), with 8GB or more recommended.
In the menu bar ON1 Effects 2020 > Preferences > Performance, try reducing the “Cache Size” or disabling “Use Graphics Processor (GPU) acceleration” (sometimes specific graphics card drivers can cause issues).
When editing very high-resolution images, try reducing the zoom ratio in the preview window before editing.

Q2: Can’t see the effect in the host software (e.g., LR) when invoked as a plugin?

Solution:

Make sure you are correctly invoking the plugin from within the host software, rather than opening ON1 Effects separately.
After completing your edits in ON1 Effects, you must click the “Apply” or “Done” button in the upper right corner for the effect to be sent back to the host software.
Check the format of the photo in the host software; compatibility with certain formats (such as some RAW formats) may require updating the plugin version.

Q3: The effect is too strong or unnatural after applying a preset?

Solution:

In the effects stack on the right, locate the filter group corresponding to the preset and directly lower its overall “Opacity” slider.
Enter the specific filters included in the preset (e.g., “Color Enhancer”) and fine-tune their intensity parameters one by one.
Use the masking brush to erase overly strong effects from key areas such as people’s faces.
