What Each Recipe Setting Actually Does

Dynamic Range: the one that needs ISO

DR100, DR200, DR400. This is highlight protection, and it is the only setting with a hard requirement attached. DR200 needs at least twice your camera's base ISO; DR400 needs four times it. Set DR400 at base ISO and the camera silently refuses.

How it works: the camera exposes the frame lower to keep the bright parts, then lifts the middle and dark tones back up while it builds the JPEG. You get highlights that hold instead of going white and slightly noisier shadows in exchange.

Use DR200 as a default outdoors. Use DR400 when the sky matters and the ground is in shade. Use DR100 indoors, at night, and whenever you want the deepest blacks a recipe can give.

Highlight and Shadow: the contrast curve

Two separate controls over the two ends of the tonal range, from −2 to +4 on X-Trans IV and V bodies. Newer bodies alolw half steps.

Positive adds contrast, negative removes it. Highlight +2 makes bright areas harder and brighter. Highlight −2 makes them softer and holds detail longer. Shadow +2 deepens the blacks. Shadow −2 opens them up and flattens the image.

The combination is what gives a recipe its mood more than anything except white balance. Highlight −1 with Shadow +1 is the classic recipe shape: protected highlights, but blacks that still look like blacks.

Colour, Colour Chrome Effect, and FX Blue

Colour is saturation, −4 to +4. Nothing more complicated than that.

Colour Chrome Effect is different, and it is the one most people misread. It does not add saturation. It adds separation inside colours that are already saturated — deep reds, dense yellows, saturated greens — where a normal JPEG would flatten them into one block. Off, Weak, Strong.

Colour Chrome FX Blue does exactly the same thing for blues. Skies and water gain gradation instead of turning into a flat panel.

Both cost nothing in speed and both are invisible on a grey day. On a bright day with a red door or a blue sky in the frame, Strong is usually the right answer.

White Balance and WB Shift: where the character lives

If you change one thing in a recipe and it stops looking like itself, this is the thing you changed.

The white balance mode sets the baseline — Auto, Daylight, Shade, or a Kelvin number. The shift then moves it on a two-axis grid: Red against Cyan, and Blue against Yellow, up to ±9 in each direction.

A shift of R +2 / B −3 is not a small correction. It is the difference between a recipe that looks like faded print film and one that looks like a straight digital file. Copy the shift exactly, including the signs, and copy the mode with it — the same shift on Auto and on Daylight gives two different pictures.

Sharpness, Noise Reduction, Clarity

Sharpness (−4 to +4) is edge contrast. Most recipes sit between −2 and +1, because the sensor already resolves more than the lens does.

High ISO NR (−4 to +4) is smoothing. Almost every recipe goes negative, and for one reason: noise reduction removes grain and fine texture together. Negative NR keeps the texture and accepts the grain, which is the point of shooting a film look in the first place.

Clarity (−5 to +5) is local contrast in the midtones. It is the one setting with a real cost: any value other than 0 makes the camera pause for about a second after each frame while it processes. If you shoot bursts or moving subjects, set Clarity to 0 and take the loss.

Grain Effect and Toning

Grain Effect is Off, Weak or Strong. Newer bodies add a size — Small or Large. Small grain reads as film at normal viewing size; Large is visible enough to be a stylistic decision rather than a texture.

Grain is applied at a fixed strength regardless of ISO, so a recipe with Strong grain shot at ISO 200 looks grainier than an untouched file at ISO 6400. That is usually what you want and occasionally a surprise.

Toning only appears on the monochrome simulations. It moves the image along a warm–cool axis: negative towards cool blue, positive towards warm sepia. On ACROS it is the difference between a print that looks like a newspaper and one that looks like a darkroom.

ISO and Exposure Compensation: why a recipe specifies them

These two are not part of of the look, and every good recipe lists them anyway.

ISO is listed because of Dynamic Range: a recipe built around DR400 cannot be used below four times base ISO, so the recipe tells you where to cap Auto ISO instead of letting you discover the limit in the field.

Exposure Compensation is listed because these looks are built at a particular brightness. A recipe that says +1/3 to +2/3 was designed slightly bright; shoot it at 0 and the shadows close up and the whole thing looks heavier than intended. Recipes for high-contrast simulations often go the other way, down to −1/3, to keep highlights off the ceiling.

What to change when it does not look right

Dial a recipe in this order, and change one thing at a time.

Too flat or too contrasty? Highlight and Shadow, not Colour. Contrast and saturation look similar on a phone screen and are not the same thing.

Wrong mood entirely? White balance and the shift. Everything else is a refinement on top of this.

Skin looks wrong? Drop Colour by one and check the red axis of the shift before touching anything else.

Too clean, does not look like film? Noise Reduction further negative before you add Grain. Grain on top of smoothed-out detail looks pasted on.

Camera feels slow? Clarity. It is always Clarity.
