Add a Vintage Effect in digiKam

Transcribed from Dmitri Popov's blog, 16 January, 2012

Want to add a vintage effect to your photos? digiKam has all the tools you need to turn your digital snapshots into vintage masterpieces. Open the photo you want for editing, adjust exposure, white balance, and tweak other settings as you would usually do. The first step in the “aging” process is to add film grain to the photo. To do this, choose Effects -> Add Film Grain. There are a lot of parameters you can configure, but you don’t have to enable and tweak them all. You can start with adjusting the Grain Size parameter as well as trying different values for parameters in the Luminance Noise section. You can preview the result at any time using the Try button. Next step is to tweak the color balance to make the photo look aged. One way to do this is to tweak the color balance settings, so the photo looks washed out with a slightly yellow cast imitating aged photo paper. Choose Color -> Color Balance and adjust the Cyan, Magenta, and Yellow parameters to achieve the desired result.

The exact values for each parameter depend on the given photo and your personal taste, but you can start with the following values:

Cyan: 37

Magenta: 25

Yellow: -25

To make the vintage effect even more realistic, add vignetting to the photo. Choose Enhance -> Lens -> Vignetting Correction, tick the Add Vignetting check box and adjust the available parameters to your liking. Finally, sharpen the photo using Enhance -> Sharpen to make the film grain more pronounced, and you are done.
