Other Filters

The photo booth creative filters apply special effects to photos and to the live view display in real time. The default set of filters is provided by PhotoboothCreativeFilter.dll, located in the installation folder.

Installing a creative filter

Copy PhotoboothCreativeFilter.dll from the installation folder into your photo booth images folder. The file can be renamed with any name ending in Filter.dll (e.g. glitch_filter.dll).

When you enter full screen photo booth mode the filter DLL is loaded automatically. Press Ctrl+Shift+C to open the filter settings dialog.

Processing filters in real time can increase CPU load and reduce live view frame rate. Set the Number of threads to more than 1 on a multi-core computer to share the load.

Available filters

Color negative

Inverts all colours (e.g. yellow appears blue, blue appears red).

Monochrome negative

Converts to greyscale then inverts (dark areas appear light, light areas appear dark).

Posterize

Thresholding/posterisation effect with adjustable number of levels. Recommended strength: 10–100.

Monochrome posterize

Converts to monochrome, posterises, then colourises with one or two colours. Controls: Strength, White highlights, Hue, Saturation, Top Hue, Top Saturation.

Saturation

Boost (above 100) or reduce (below 100) colour saturation. Setting to 10 produces near-greyscale; setting to 200 produces vivid colours.

Pop Art

Three-colour “pop art” effect reminiscent of Andy Warhol’s style. Requires a green or blue background and continuous lighting. Set Threshold to ~140, Sensitivity to ~6, and adjust Background hue until the background replaces correctly.

Mirror filters

Mirrors different parts of the photo:

• Mirror left/right
• Mirror top/bottom
• Mirror 2×2 mosaic
• Mirror swap top halves (landscape only)

Mirror left/right and Mirror top/bottom behave differently when the camera is in portrait orientation — swap the two options if results appear incorrect.

User selection of filters via profiles

Different filters can be offered as user choices by creating separate photo booth images folders (e.g. normal, over, under), each with its own settings file and filter DLL configured differently. Assign each folder to a profile and provide touchscreen actions to let users select.

Saving filtered photos

Enable Save copy of processed photos in Output Settings to save a copy of each photo after the creative filter has been applied.
