X-Trans IV and X-Trans V cameras render the Classic Chrome, Classic Negative, Eterna, and Eterna Bleach Bypass film simulations with slightly deeper blue on V than on IV. The rule of thumb is: if a fourth-generation recipe uses one of those four film sims, reduce Color Chrome FX Blue by one step (Weak instead of Strong, Off instead of Weak) on the fifth-generation camera. This converter handles that for you, plus the Grain Size scaling for GFX cameras, the +0.5 Shadow nudge on GFX50S II, and the X-Trans IV → III/II downgrade path.
When taking an X-Trans IV recipe to an X-Trans V body, if it uses Classic Chrome, Classic Negative, Eterna, or Eterna Bleach Bypass, drop Color Chrome FX Blue by one (Strong→Weak, Weak→Off). Everything else stays the same.
Changes the converter made
X-Trans IV to V conversion paths.
| From | To | Rule |
|---|---|---|
| X-Trans IV | X-Trans V | If recipe uses Classic Chrome, Classic Negative, Eterna or Eterna Bleach Bypass: drop Color Chrome FX Blue by one (Strong→Weak, Weak→Off). |
| X-Trans IV | X-Trans IV + X-Processor 5 (X-S20, X-M5, X-T30 III) | Treat as X-Trans V, drop CCFX Blue by one on the four affected sims. |
| X-Trans V | X-Trans IV | Reverse direction: raise CCFX Blue by one (Off→Weak, Weak→Strong) on the four affected sims. |
| X-Trans IV | X-T3 / X-T30 (original) | Skip Clarity (unavailable), skip Color Chrome FX Blue (unavailable), Grain Strong only (no size selection). |
| X-Trans IV | X-Trans III | All above + reject Classic Negative and Eterna Bleach Bypass, substitute Classic Chrome or skip recipe. |
| X-Trans IV | X-Trans II | All above + reject Eterna, PRO Neg. Hi and Acros (substitute Monochrome). |
| X-Trans V | Modern GFX (GFX100 II / 100S II / 100RF) | No change required, render is virtually identical. |
| X-Trans IV | GFX50S II | Add +0.5 to Shadow on the legacy GFX 50MP body. |
| Anything | X-T30 III / X-M5 / X-S20 | Always treat as V target regardless of source. |
Fujifilm sensor generation capabilities.
Each row is cumulative, every later sensor inherits the row above.
X-Trans I
2012Provia, Velvia, Astia, PRO Neg. Std/Hi, Monochrome only. No Grain, no Color Chrome, no Classic Chrome, no Acros, no Clarity, no CCFX Blue.
X-Trans II
2013–2016Added Classic Chrome (X30 / X100T / X70 era only).
X-Trans III
2016Added Acros, Grain (no size selection), Eterna (X-H1 only).
X-Trans IV early
2018Added Color Chrome Effect. Still no Grain Size / CCFX Blue / Clarity (X-T3, X-T30).
X-Trans IV late
2019–2021Added Classic Negative (X-Pro3), Grain Size, Color Chrome FX Blue, Clarity, Eterna Bleach Bypass (X-T4).
X-Trans V
2022–Deeper blue rendering on Classic Chrome / Classic Negative / Eterna / Eterna BB. Nostalgic Neg. and Reala Ace added (X100VI / X-T50 in 2024).
GFX recipe conversion.
Modern GFX (100 II / 100S II / 100RF)
Renders closest to X-Trans V. No conversion needed for most recipes, copy straight from any X-Trans V source. Grain scales differently from X-Trans because the sensor is larger, but the simulation tone curves are essentially the same.
GFX50S II / 50R / 50S
The 50MP legacy GFX bodies need Shadow +0.5 added relative to any X-Trans IV recipe, the older sensor lifts deep blacks less. They also lack Reala Ace, Nostalgic Neg. and Eterna Bleach Bypass.
X-Trans recipe conversion examples.
Kodachrome 64, IV → V
Source: Classic Chrome, CCFX Blue Weak. Target: X-Trans V (X100VI / X-T5). Output: CCFX Blue Off. Every other parameter identical.
Pacific Blues, IV → III
Source: Classic Negative, CCFX Blue Strong, Clarity +1. Target: X-Trans III (X-Pro2 / X-T2). Output: Marked incompatible, Classic Negative did not arrive until X-Pro3. Substitute Classic Chrome and add WB +2B.
Reggie's Portra, V → GFX100 II
Source: Classic Chrome (X-Trans V), CCFX Blue Off. Target: modern GFX. Output: identical, modern GFX renders X-Trans V recipes 1:1 with no changes.
Common questions.
The X-Trans V sensor and X-Processor 5 combination renders Classic Chrome, Classic Negative, Eterna and Eterna Bleach Bypass with deeper blue than X-Trans IV. The other simulations (Provia, Velvia, Astia, Acros, etc.) render visually identical across generations.
Close, not identical. The CCFX Blue adjustment fixes the dominant difference but there are second-order tone-curve differences between X-Processor 4 and X-Processor 5 that no setting change fully corrects. Most photographers describe the result as 'within noise floor' of the original recipe's intent.
These bodies pair an X-Trans IV sensor with X-Processor 5. The processor difference dominates, they render closer to X-Trans V than to X-Trans IV. Treat them as V targets for purposes of CCFX Blue. The converter does this automatically when you pick 'X-Trans IV + X-Processor 5' as the target.
Yes. Acros and Monochrome render visually identically across X-Trans III, IV and V, no Color Chrome FX Blue adjustment applies. The converter passes B&W recipes through unchanged unless the target sensor is too old to support Acros (in which case it flags incompatibility).
No. Nostalgic Neg. and Reala Ace are X-Processor 5 only, they cannot be rendered on X-Trans IV bodies (X-T4, X100V, X-Pro3, etc.) regardless of settings. The converter marks these as incompatible with a clear reason.
Usually no. Many photographers happily run unmodified X-Trans IV recipes on X-Trans V bodies, the deeper blue is a subtle shift, not a wrong colour. Convert when you want the recipe creator's exact look. Don't convert when you like how the unmodified version renders.
