Detail

The Detail section is for sharpening, micro-contrast, and chromatic aberration cleanup. Open the Adjustments panel with D and scroll to Detail.

Sharpening

Slider	Range	What it does
Sharpness	−100 to +100	Edge enhancement via unsharp masking. Negative values soften (a mild blur); positive values sharpen edges.

Sharpness in RapidRAW is frequency-aware. It boosts contrast at edges by subtracting a blurred version of the image from the original and adding the difference back. This sharpens edges without much effect on smooth areas.

For most photos, +25 to +60 is a sensible range. Above +75, sharpening artifacts (haloing, noise emphasis) start to appear at 100% zoom. View at 100% (Ctrl+1) when judging.

Presence

Three "local contrast" sliders that operate on different frequency bands. Use them in combination, not just one.

Slider	Range	What it does
Clarity	−100 to +100	Mid-to-high frequency contrast. Brings out small textures (rocks, leaves, fabric). Lighter touch than Structure.
Dehaze	−100 to +100	Haze and atmospheric scattering removal. Increases local contrast and saturation in low-contrast areas. Negative adds haze.
Structure	−100 to +100	Low-frequency texture enhancement. Negative softens skin and atmospheric haze; positive adds "punch" and depth.
Centré	−100 to +100	Center-weighted detail emphasis. Applies more of the above effect to the image center, fading toward the edges. Not available in masks.

When to use which

Clarity for textile, foliage, rough surfaces. Subtler than Clarity; combines well with it.
Dehaze for distant landscapes, smoke, fog, or any low-contrast haze you want to cut through.
Structure for landscapes, architecture, anything with broad tonal regions where you want depth. Use sparingly on faces (negative Clarity is good for skin).
Centré when the subject is roughly centered and you want the focus to feel concentrated there. Pairs well with a positive Clarity.

Chromatic Aberration

Two sliders to manually correct lateral chromatic aberration (color fringing on high-contrast edges). Most lenses produce some.

Slider	Range	What it does
Red/Cyan	−100 to +100	Shifts the red channel relative to green, correcting red-cyan fringes.
Blue/Yellow	−100 to +100	Shifts the blue channel relative to green, correcting blue-yellow fringes.

Not available inside masks: apply globally. Most users won't need to touch these if they enable lens corrections in the Crop & Geometry panel, which uses the Lensfun database to apply known corrections automatically.

To see and judge fringing, zoom to 100% on a high-contrast edge (a tree branch against bright sky is a good test) and watch the colored halos.

What's available in masks

Group	In masks?
Sharpening (Sharpness)	Yes
Presence: Clarity, Dehaze, Structure	Yes
Presence: Centré	No (global only)
Chromatic Aberration	No (global only)

When working inside a mask, you can locally raise Clarity or Sharpness on a subject without sharpening the whole image. Useful for portraits where you want strong eyes but smooth skin elsewhere.

A word on noise reduction

You won't find noise reduction sliders here. RapidRAW does not ship a manual noise-reduction slider for everyday work; instead, it offers AI Denoise accessed from the right-click Productivity menu in the library for local or batch processing. See Batch Processing → Batch denoise.
