Filter Gallery
Filter Gallery is a plugin with the 20 Visual.af effects in a single window. You choose by looking at thumbnails of your layer, adjust with a live preview and compare before and after, then apply.
Installation
The installer copies the plugin into the Affinity plugins folder and turns on the setting Affinity needs to load it.
Download FilterGallery-Setup.exe. It doesn’t need administrator permissions.
Click “OK”: it copies Filter Gallery into Affinity and turns on “Allow "Unknown" plugins to be used”, which Affinity needs. If Windows shows “Windows protected your PC”, click “More info” and then “Run anyway”.
Choose Filters › Plugins › Visual.af › Filter Gallery with a pixel layer selected. The effect is applied to that layer, so duplicate it first with Ctrl+J if you want to keep it.
Download FilterGallery-Setup.pkg. It doesn’t need administrator permissions.
Click “Continue” and then “Install”. It copies Filter Gallery into Affinity and turns on “Allow "Unknown" plugins to be used”, which Affinity on Mac needs.
Select a pixel layer and choose Pixel › Filters › Plugins › Visual.af › Filter Gallery. The effect is applied to that layer, so duplicate it first with ⌘J if you want to keep it.
Yes. Download the Mac installer (FilterGallery-Setup.pkg): it works with Affinity 3 on Macs with Apple Silicon or Intel. The installer is signed and notarized by Apple, so it opens without warnings.
It can happen. Because Filter Gallery is new, Windows SmartScreen doesn’t know the installer yet and may show “Windows protected your PC”. It is 100% safe: click “More info” and then “Run anyway”.
Go to Settings › Photoshop Plugins, turn on “Allow "Unknown" plugins to be used” and restart Affinity. Also select a pixel layer before you open the Plugins menu: the filter only works on a selected pixel layer.
Affinity 3, on Windows 10 or 11 or on a Mac.
Like every filter in Affinity, it works on pixel layers. To apply an effect to text, vectors or a group, duplicate it and turn the copy into pixels first (rasterize it).
No. Like every filter in Affinity, the effect is applied to the selected layer. Duplicate it first with Ctrl+J (⌘J on a Mac) if you want to keep the original, or undo with Ctrl+Z (⌘Z).
On three. If you change computers, you can free one up from the window itself with your purchase email.
Only to activate the license and check for updates. The effects are calculated on your computer and your images never leave it. Offline, the license keeps working for 14 days.
When there’s a new version, the window shows a notice with an “Update” button. Affinity uses the new version the next time it starts.
