To add film grain to a photo, start with a small grain size and raise Strength until the texture becomes visible at your intended output size. In Artfkt’s free browser demo, add Film Grain, keep Still selected, adjust its controls and choose Export → PNG.

A grain filter can give a smooth wall or sky a visible surface. Too much can bury the same edges you want to preserve. These examples use one photograph, the same exposure and the same framing, so you can see what each control contributes.

Compare the original, restrained and heavy grain

This photograph of pink and blue architecture is by Maxine Yang, used under the Unsplash License. The quiet walls and sky expose added texture; the roof edges and window details help show when it starts competing with the photograph. “Original” means no Artfkt effect has been added, not that the photograph has no existing texture or noise.

Original — no added Artfkt Film Grain.
The same full-frame architecture photograph with fine added grain.
Strength 0.12 — added texture remains finer than the building details.
The same architecture photograph with much stronger grain across walls and sky.
Strength 0.35 — the texture becomes a conspicuous part of the image.

Try Film Grain on your photo. The link opens the current Film Grain sample with its default settings, not this architecture photograph or the settings below. Choose Use your own image to replace the sample while keeping the controls. Apply the listed settings separately to reproduce this treatment.

Only Strength changes between the two treated images. It controls how strongly the grain contributes; it does not change the size of the pattern. The restrained example is a starting point for this image, not a universal prescription.

Look at matching native-resolution crops

These are the same 384 × 384 pixel area of each 1600 × 901 render, with no extra sharpening or enlargement in the files. The page may scale them to fit your screen. Compare at native size when judging fine texture.

Add grain to your own photo

  1. Open Film Grain in the free demo in your browser and choose Use your own image.
  2. Select Still, open Active FX, and expand Film Grain.
  3. Start with a low Strength. Look at a quiet area and a detailed edge rather than judging only the whole thumbnail.
  4. Set Grain size, then try Clump. Change one control at a time.
  5. Set Variation rate to 0 Hz for a held grain pattern. Use Mix to compare, then choose Export → PNG.

Exact settings for the restrained image:

Control Setting
Strength 0.12
Grain size 0.22% (stored value 0.0022)
Clump 0.72
Chroma 0.35
Shadow weighting 0.60
Seed 37
Variation rate 0 Hz
Mix and blend 100%, Normal

All parameter motion is off in these still comparisons. The heavy version changes only Strength to 0.35. The photograph was resized proportionally to 1600 × 901 before rendering; its full framing is preserved. Exporting your own photo keeps its source dimensions in this workflow.

Fine grain or coarse grain?

Grain size changes the pattern’s scale relative to the image. Fine grain can read as a surface; coarse grain can become a visible pattern of its own. A large setting can overwhelm small type or delicate detail.

Architecture photograph with fine added grain at Grain size 0.12 percent.
Grain size 0.12% — finer texture.
The same photograph with coarse grain at Grain size 0.80 percent.
Grain size 0.80% — larger visible clusters.

For this pair, Strength is 0.18, Clump is 0.72, and all other settings match the table. Only Grain size changes, from 0.12% to 0.80%. Size can also change how strong the texture appears; compare both images at the same display size.

Even texture or clumped clouds?

Clump gathers the grain into softer, uneven clouds. At zero, the texture is more evenly distributed. Raising it does not select the subject or follow an object’s outline.

Architecture photograph with evenly distributed added grain and Clump zero.
Clump 0.00 — more even texture.
The same photograph with grain gathered into uneven clouds at Clump 0.72.
Clump 0.72 — more clustered texture.

Both use Grain size 0.40%, Strength 0.18 and the remaining table settings. Only Clump changes. Check the sky and walls for the texture’s distribution, then look back at the building edges.

Color, shadows and motion

Chroma adjusts the colored contribution to the grain. Lower it when colored specks distract from the photograph. Shadow weighting gives darker regions more grain emphasis; judge it against your own image’s tonal balance. Neither control restores detail missing from the source.

Seed chooses a repeatable pattern. Variation rate 0 Hz holds it over time. To refresh the grain during playback, choose Animate, keep the parameter motion off if you want their values fixed, and raise Variation rate. That changes the texture over time; it does not turn the still PNG into an animated file.

For a bright edge treatment instead, compare Halation vs Bloom. For dust, scratches, faded tones or chemical interpretations, explore the Film collection. These are artistic image treatments, not calibrated reproductions of a particular film stock.

Try the photo before saving a project

Try Film Grain on your photo and export a still PNG for free. Judge the exported file at its intended size; texture that looks pleasant in a large working view can become distracting or disappear when reduced.

Choose Artfkt desktop for Mac and Windows when you want to save and revisit an editable composition, keep reusable saved looks, or work with the remaining desktop collections. Film Grain, Halation and Light Leak are already available in the free browser demo. Check the computer requirements before buying.
