XnRetro is a free to use (but not open source) tool available for Linux, Windows and Mac OS X (as well as iOS and Android) that allows you to easily apply various vintage effects, borders and more to your images.
There are many applications you can use to apply effects to your photos but XnRetro is one of the easiest to use, comparable to Instagram I'd say: you simply select an image and the effect you want to apply (you can use multiple effects if you want) and you immediately get a preview. You can then save the image or share it on websites such as Facebook, Flickr, Picasa, Imgur and so on:
The application also allows you to tweak the effects by adjusting various settings such as the brightness, contrast, exposure, saturation, noise, rotate the picture and so on.
Please note that in my test under Ubuntu 13.04, XnRetro failed to upload images to some websites, such as Imgur or Imageshack, so this feature is a bit buggy for now, at least on Linux.
- 20 color effects;
- 15 light effects;
- 5 Vignette effects;
- 28 frame borders;
- adjustable contrast, gamma, saturation and so on;
- share the resulted image on Flickr, Picasa, Facebook, Imgur, Tumblr, ImageShack, YFrog, GlowFoto or TwitPic.
Note for Linux users: there's only a 32bit binary but it should work on 64bit (I've tested it under Ubuntu 13.04 64bit). To run it, extract the downloaded archive and double click "xnretro.sh", then select "Run". You can also run it by double clicking "XnRetro" but that might not work on all Linux distributions.
thanks to Satya for the tip!
