Unclipped

Introduction
The "Unclipped" processing profile (introduced in RawTherapee 5.6) allows one to save an image in a way which preserves data across the whole tonal range, including clipped shadows and highlights, thus allowing for strong exposure adjustments and dynamic range compression of the saved file while retaining detail in the shadows and highlights. This may be desired not only for scientific purposes but also when the saved image is destined for further manipulation and the final exposure is yet unknown, such as can be the case when stitching panoramas which require exposure adjustments so that images seamlessly blend into one another.

Not all tools can be used when saving an unclipped image. The following tools or settings are known to be incompatible with saving unclipped images in RawTherapee 5.6, and so are disabled by this processing profile:
 * Exposure tone curves,
 * Vibrance,
 * Before/After curves in the Black-and-White tool,
 * Film Simulation,
 * RGB Curves in luminosity mode,
 * DCP look table,
 * CIECAM02

Usage

 * 1) Apply the Unclipped profile. This profile disables those tools and settings which are incompatible with saving unclipped images.
 * 2) * If you want to apply this profile and reset all tools to safe default values, then set the processing profile fill mode to "Filled" [[File:Profile-filled.png]] before applying this profile.
 * 3) * If you want to apply this profile while preserving existing adjustments, then set the processing profile fill mode to "Preserve" [[File:Profile-partial.png]] before applying this profile.
 * 4) Save the image as either a 16-bit floating-point TIFF or a 32-bit floating-point TIFF.
