Do you have a lot of photographs of buildings? But, you never used a tilt-shift lens to prevent converging verticals? If so this neat little program is for you, it deconverges and so straightens up your buildings (without having to buy Photoshop to do that manually or with an action). Make your photos more intuitive with a one-click solution.
I took a photo using a standard lens of St Peter and Paul’s Church in Aldeburgh, on the Suffolk coast and applied their one-click fix. You do lose some of the periphery of the photo, but this crop looks a lot better than the original, I think.
