Fujifilm X100VI photo filter
A Fujifilm X100VI photo filter with modern JPEG detail and three considered rendering modes.
This effect approximates a documented capture and processing recipe on an existing image. It is not a measured or exact reproduction.
Behind the camera look
The original camera
The X100VI pairs a 40.2-megapixel APS-C X-Trans CMOS 5 HR sensor with a fixed 23mm f/2 lens. Its high-resolution capture and its processing choices are separate parts of the result. Applying this filter to an existing image cannot reproduce the sensor’s sampling pattern or supply detail that the input never contained. [1]
Fujifilm’s manual presents PROVIA / Standard as an all-purpose option and describes Classic Chrome through subdued color and stronger shadow contrast. ACROS is a monochrome simulation. The camera also exposes grain and other image-quality settings independently, so a useful interpretation needs to distinguish the selected simulation from additional texture. [2]
Our interpretation
Classic Chrome is our default. We chose a restrained color response and stronger tonal separation to make its direction visible beside the other cameras. PROVIA / Standard provides a more colorful, general-purpose interpretation. ACROS removes color and changes contrast and texture. These are authored RGB treatments inspired by the documented modes, not copies of Fujifilm’s undisclosed processing.
Clarity adjusts local detail, while Highlights softens the bright end of the response. Neither operation restores clipped information. Start with a well-exposed photograph and compare bright fabric, skin, and textured surfaces before increasing either control. The default avoids added Grain, allowing the processing interpretation to remain the main difference between this treatment and the analog cameras.
ACROS texture can remain visible with Grain at zero when Noise is above zero. In the implementation, Noise and ISO influence brightness-dependent monochrome texture; Grain adds a separate layer. Fujifilm’s 2016 explanation describes sensitivity- and brightness-dependent texture as part of ACROS itself. That account supports this distinction, but predates the X100VI and does not disclose a calibrated algorithm for it. Our monochrome target uses zero monochromatic color adjustments. [3]
Evidence and limits
The research included a full-size Fine JPEG from Mark Goldstein’s X100VI review and a smaller manufacturer-gallery photograph. These helped us inspect general detail and tonal rendering. Their complete processing settings, simulation choices, and firmware were not verified, so differences between those photographs cannot demonstrate differences between PROVIA, Classic Chrome, and ACROS. [4]
The skate photograph preview is our filter applied to the common comparison photograph, not an X100VI capture. All three responses remain unmeasured approximations. A meaningful fidelity comparison would require matched scenes and known camera settings, including white balance, dynamic-range options, and noise reduction. The filter does not perform X-Trans demosaicing, simulate stabilization, or recover RAW information. With a monochrome recipe, reducing Mix blends the original image back in, including any original color.

Creative applications
- Detailed street and travel photographs.
- Color and monochrome alternatives for a consistent photo series.
Starting workflow
- Start with a well-exposed image. Classic Chrome is the default; switching recipes keeps your other edits.
- Start with Clarity, then adjust Highlights to soften bright tones. ACROS retains its sensitivity-shaped texture independently of Grain.
- Adjust Exposure before tuning the optical, response or texture controls.
- Compare with the source using Mix and inspect fine edges at the intended output size.
Key controls
- Clarity
Start with Clarity, then adjust Highlights to soften bright tones. ACROS retains its sensitivity-shaped texture independently of Grain.
Default: 0% · Range: -100% to 100%
- Simulation
Interpretation of selected documented simulation. Switching recipes preserves other control values.
Default: Classic Chrome · Choices: PROVIA / Standard, Classic Chrome, ACROS
- ISO
Noise target; not exposure or DR mode.
Default: 125 · Choices: 125, 800, 3200, 6400
- Highlights
Additional bright-tone compression; 0 keeps recipe curve alone.
Default: 25% · Range: 0% to 100%
- Grain
Optional stable output grain; 0 off.
Default: 0% · Range: 0% to 100%
- Noise
Multiplier on ISO-related digital texture, including ACROS monochrome texture independently of optional Grain; 0 off.
Default: 1 · Range: 0 to 2
- Exposure (EV)
Trim input brightness before processing; clipped detail cannot be recovered.
Default: 0 · Range: -2 to 2
- Mix
Blend with the source; zero bypasses the treatment.
Default: 100% · Range: 0% to 100%
- Seed
Choose a repeatable texture arrangement. Variation rate controls whether it changes during playback.
Default: 17 · Range: 0 to 65535
- Variation rate
Zero holds the seeded texture. Raise Variation rate and enable animation for deterministic texture changes during playback; returning to the same time reproduces the pattern.
Default: 0Hz · Range: 0Hz to 30Hz
Practical tips
- Judge texture at the final display or export size.
- Use the same source and exposure when comparing camera treatments.
Limitations
- Approximates selected JPEG modes; does not implement Fujifilm processing, X-Trans demosaicing, RAW development or highlight recovery.
- Existing grades, compression and clipping remain part of the input. Recipe fidelity has not yet been validated against matched captures.
- Brand and model names identify the inspiration; no manufacturer endorsement is implied.
