{{From|https://help.ubuntu.com/community/Photos/Sepia}} {{Languages|UbuntuHelp:Photos/Sepia}} #title Sepia Photos It is possible to make modern digital photos look old-fashioned by applying a ''sepia'' effect. ''See [http://en.wikipedia.org/wiki/Sepia_tone Wikipedia] for more information on sepia photos.'' === Using the GIMP Image Editor === {|border="1" cellspacing="0" |https://help.ubuntu.com/community/Photos/Sepia?action=AttachFile&do=get&target=gimp-sepia.png |} The GIMP provides a filter especially for making images look old. Alternatively, you can add a sepia effect manually. ==== Use the Old Photo filter ==== <ol><li>Open a photo in the ''GIMP Image Editor'' </li><li>Press '''Script-Fu''' -> '''Decor''' -> '''Old Photo...''' </li><li>Ensure that ''Sepia'' is ticked and press '''OK''' to apply the effect (see screenshot) </li><li>If the resulting image appears too light, increase the contrast: <ol><li>Press '''Tools''' -> '''Color Tools''' -> '''Brightness-Contrast...''' </li><li>Ensure that ''Preview'' is ticked </li><li>Move the ''Contrast'' slider to the right to increase the contrast </li><li>Press '''OK''' when you are happy with your changes</li></ol> ==== Manually add a sepia colour effect ==== <ol><li>Open a photo in the ''GIMP Image Editor'' </li><li>Press '''Tools''' -> '''Color Tools''' -> '''Hue-Saturation...''' </li><li>Under ''Select Primary Color to Modify'', ensure that '''Master''' is selected </li><li>Move the ''Saturation'' slider as far to the left as possible and press '''OK'''. This will make the photo black and white </li><li>Press '''Tools''' -> '''Color Tools''' -> '''Color Balance...''' </li><li>Under ''Modify Selected Range's Color Levels'':</li></ol> * Move the ''first'' slider towards ''Red'' (about 45) * Move the ''third'' slider towards ''Yellow'' (about -45) <ol><li>Once you are happy with the way the photo looks, press '''OK'''</li></ol> === Using F-Spot Photo Manager === ''[[UbuntuHelp:F-Spot|F-Spot]]'' is able to convert photos to sepia, although you will probably get better results if you use the ''GIMP Image Editor''. <ol><li>Open ''[[UbuntuHelp:F-Spot|F-Spot]] Photo Manager'' and find a photo </li><li>Double-click the photo </li><li>Press '''Convert the photo to sepia tones''' (see below)</li></ol> https://help.ubuntu.com/community/Photos/Sepia?action=AttachFile&do=get&target=fspot-sepia.png [[category:UbuntuHelp]]
