Two Free border presets (white and black) for Adobe Photoshop Lightroom 3 and Lightroom 4
It is possible to add a white or black border in Lightroom in the Effects panel of the Develop Module (by adjusting the style and three of the sliders)
I have also created a Preset so that I can add the effect with a single click. I am making these presets available for FREE here.
Note > Adding a border with either of these presets will remove a vignette if you have applied one prior to clicking on the preset. If you want a vignette and border you will need to apply the preset to a copy of your previously edited file.
