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.

Reset

The Reset settings button clears every filter in one action.
