{{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%7C% |} The GIMP provides a filter especially for making images look old. Alternatively, you can add a sepia effect manually. ==== Use the Old Photo filter ==== # Open a photo in the ''GIMP Image Editor'' # Press '''Script-Fu''' -> '''Decor''' -> '''Old Photo...''' # Ensure that ''Sepia'' is ticked and press '''OK''' to apply the effect (see screenshot) # If the resulting image appears too light, increase the contrast: ## Press '''Tools''' -> '''Color Tools''' -> '''Brightness-Contrast...''' ## Ensure that ''Preview'' is ticked ## Move the ''Contrast'' slider to the right to increase the contrast ## Press '''OK''' when you are happy with your changes ==== Manually add a sepia colour effect ==== # Open a photo in the ''GIMP Image Editor'' # Press '''Tools''' -> '''Color Tools''' -> '''Hue-Saturation...''' # Under ''Select Primary Color to Modify'', ensure that '''Master''' is selected # Move the ''Saturation'' slider as far to the left as possible and press '''OK'''. This will make the photo black and white # Press '''Tools''' -> '''Color Tools''' -> '''Color Balance...''' # Under ''Modify Selected Range's Color Levels'': #* Move the ''first'' slider towards ''Red'' (about 45) #* Move the ''third'' slider towards ''Yellow'' (about -45) # Once you are happy with the way the photo looks, press '''OK''' === Using F-Spot Photo Manager === ''F-Spot'' is able to convert photos to sepia, although you will probably get better results if you use the ''GIMP Image Editor''. # Open ''F-Spot Photo Manager'' and find a photo # Double-click the photo # Press '''Convert the photo to sepia tones''' (see below) https://help.ubuntu.com/community/Photos/Sepia?action=AttachFile&do=get&target=fspot-sepia.png [[category:UbuntuHelp]]
