Film Grain

Classic photographic film grain pattern that simulates the organic texture of silver halide crystals in traditional film. This grain structure has a natural, random distribution with subtle clumping that creates a pleasing texture. Ideal for creating authentic analog photography looks with organic, natural-feeling texture.

Digital Noise

Replicates the noise pattern produced by digital cameras at higher ISO settings. Unlike film grain, digital noise has a more regular, less organic pattern with occasional "hot pixels" and a slightly blockier appearance. Perfect for modern photography effects or when simulating shots taken in low-light conditions.

Classic Grain

Features a more uniform, fine-grained pattern inspired by classic black and white films of the mid-20th century. This grain type has a softer, more consistent texture than standard film grain, creating a timeless, refined look. Excellent for black and white conversions or when a subtle, consistent texture is desired.

Heavy Grain

A bold, pronounced grain pattern that simulates high-speed film or push-processed photography. The grain clumps are larger and more defined, creating a highly textured, dramatic effect. Use this for creative artistic effects, gritty documentary-style imagery, or to add strong character to images.

Fine Grain

Extremely subtle, high-frequency grain pattern that emulates low-ISO professional films. This grain type adds texture without being immediately noticeable, giving a gentle "filmic" quality. Perfect for adding minimal texture to professional portraits or when a clean but not sterile look is desired.

Dust & Scratches

A unique effect that combines fine grain with simulated dust spots and film scratches. This creates an authentic vintage look that mimics old, handled film or aged photographs. Ideal for creating nostalgic, archival aesthetics or for artistic projects requiring a weathered appearance.

Blend Modes

The blend mode determines how grain interacts with your image's underlying pixels:

• • Overlay: Preserves highlights and shadows while adding grain to midtones (most natural look)
• • Soft Light: Adds subtle grain without affecting contrast (gentlest option)
• • Screen: Brightens the image while adding grain (good for dark photos)
• • Multiply: Darkens the image while adding grain (creates a moodier effect)
• • Hard Light: Creates higher contrast with pronounced grain (more dramatic look)

Fine-Tuning Parameters

• • Contrast: Increases the difference between the grain's light and dark areas. Higher values create more visible, "punchier" grain that stands out from the image.
• • Roughness: Controls how much the grain "clumps" together. Higher values create more irregular patterns with greater variation in grain density.
• • Opacity: Determines the overall visibility of the grain effect. Lower values create a more subtle blend with the original image.
• • Color Variation: Adds random color shifts to the grain pattern. Higher values create more colorful grain, while zero keeps the grain neutral.

Random Pattern Generation

The "New Pattern" button creates a fresh random seed for the grain pattern while keeping your settings the same. This is useful when you like your current grain settings but want to try a slightly different pattern. Each time you click "Apply Grain" or "New Pattern," a unique variation is generated, similar to how no two sheets of film have exactly the same grain pattern.
