Test Your R/B Shift
R: +2 · B: -5
Live preview
Load a Fujifilm Recipe’s R/B Values
Use the R/B Grid
Move the point diagonally to generally shift the preview warmer or cooler. Move it in other directions to change the color cast. Adjust the R/B position and watch the preview respond instantly as you test different values.
Check Kelvin Shift Values
Scan this Kelvin quick reference to find approximate R/B shifts at a glance; values become non-linear at extreme settings.

| 3200K | Studio tungsten | +6R / -6B |
| 4000K | Fluorescent (warm white) | +3R / -3B |
| 5000K | Cool morning sun | +1R / -1B |

Why Isn't My WB Shift Saving?
Some Fujifilm bodies store WB Shift globally by WB type instead of saving it inside each Custom Setting/C-slot. If yours behaves this way, assign different WB types to different recipes. The behavior varies by camera generation.
Create a Custom WB Shift
- 01
Start at 0R/0B
- 02
Adjust Red and Blue on the grid
- 03
Preview each change on Skin, Sky, and Foliage
- 04
Keep the winning R/B value
Common questions.
You can select a Fujifilm recipe from the Recipe Shift Loader to load its stored R/B values into the grid automatically. We then display the selected shift so you can preview the result before using it.
You can set an exact custom value such as +3R/-5B directly on the interactive grid. We update the Skin, Sky, and Foliage previews immediately, so you can test the selected shift before applying that value elsewhere.
You can see the Red and Blue values together in the live coordinate readout. We display the current position as a combined R/B value, such as R: +2 · B: -5, while the grid updates with every adjustment.
You can test different WB Shift settings by moving the grid point between values and watching the live previews change. We let you compare the visual response of one setting with another without leaving the tool.
You can use the Kelvin reference as a quick approximation rather than an exact conversion. We show approximate R/B shifts for common Kelvin values, with the relationship becoming non-linear at extreme settings.
You can load 25+ preloaded Fujifilm recipes, including Reggie’s Portra, Kodak Portra 400 v2, Kodachrome 64, Classic Chrome (Roesch), Fujicolor Superia 800, Ektar 100, Vintage Agfacolor, Pacific Blues, and others.
