<p>Here&#39;s a quick and easy way to give your photo a <a href="https://www.thoughtco.com/apply-a-sepia-tone-to-photo-1700240" data-type="internalLink" data-component="link" data-source="inlineLink" data-ordinal="1">sepia tone</a> effect with the free <a href="https://www.gimp.org/" data-type="externalLink" data-component="link" data-source="inlineLink" data-ordinal="2">GIMP</a> photo editor. Best of all, it&#39;s completely non-destructive, so if you change your mind, you can go back to the edited photo easily.</p><p>This tutorial uses GIMP 2.6. It should work in later versions, but there may be differences with older versions.</p><p>Open the image you want to work with in the GIMP.</p><p>Go to the color chooser at the bottom of the toolbox, click the foreground color swatch, and choose a reddish-brown color. The exact color is not important. I will show you how to adjust it in a later step.</p>Go to the Layers palette and click the New layer button. In the New layer dialog box, sett he layer fill type to Foreground color and click OK. The new brown color layer will cover the photo.In the layers palette, click the menu arrow next to &#34;Mode: Normal&#34; and select Color as the new layer mode.The result might not be the exact sepia tone effect that you want, but we can fix that. The original photo is untouched in the layer below as we have only applied the color as a layer blending mode.Make sure the brown fill layer is still the selected layer in the layer&#39;s palette, then go to Tools &gt; Color Tools &gt; Hue-Saturation. Move the Hue and Saturation sliders until you are satisfied with the sepia tone. As you can see, by making large adjustments to the Hue slider, you can create color toning effects other than sepia toning.To return to the original photo, just turn off the eye icon on the layers palette next to the color fill layer.
