Filter

The Filter subsection applies visual effects to an element (image, video, block): opacity, brightness, contrast, saturation, hue, grayscale, blur and sepia. Particularly useful to harmonize varied photos or to create an artistic rendering.

Preset filters

The Preset filters selector offers five ready-to-use presets:

• None: clears every filter.
• Sepia: warm tone like an old photograph.
• Monochrome: image in black and white.
• Soft: increased brightness and slightly reduced contrast, for a bright, calm rendering.
• Vivid: increased contrast and saturation, for a punchier rendering.

Choosing a preset automatically configures the sliders below, which you can then refine.

Individual sliders

You can adjust each effect independently:

• Opacity (0–100%): overall transparency.
• Brightness (0–200%): brightens (>100) or darkens (<100).
• Contrast (0–200%): accentuates or dampens the difference between light and dark tones.
• Saturation (0–200%): intensifies the colors (>100) or fades them down to black and white (0).
• Color (hue) (0–360°): rotates every color around the color wheel.
• Grayscale (0–100%): progressively desaturates toward black and white.
• Blur (0–20 px): applies a progressive blur.
• Sepia (0–100%): progressively applies the sepia tone.

These effects combine: you could for example apply 30% grayscale + 110% brightness for a retro look.

The Reset settings button clears every filter in one action.
