== Create a Bleach Bypass Effect in digiKam ==
Transcribed from Dmitri Popov's blog, 2 April 2013

Using tools available in '''digiKam''', you can simulate a number of effects, including bleach bypass. This effect produces a desaturated high-contrast image. Creating the bleach bypass effect in '''digiKam''' is done in two simple steps. Open a photo for editing and choose <menuchoice>Color -> Hue/Saturation/Lightness</menuchoice>. Specify the desired saturation value somewhere between -35 and -59, then press <menuchoice>OK</menuchoice> to desaturate the photo.

Choose then <menuchoice>Color -> Curves Adjust</menuchoice>, select <menuchoice>Luminosity</menuchoice> from the '''Channel''' drop-down list, and adjust the curve so it’s shaped as S. Feel free to experiment with the steepness of the curve to achieve the best result. As a starting point, you can download a [http://dmpop.homelinux.com/digikamrecipes/files/s.crv ready-made S curve] and import it into '''digiKam''' using the <menuchoice>Load</menuchoice> button.
