Save unclipped images

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.

I always thought, only german language would use such long sentences
