  • Generic Company Place Holder ShiftN

ShiftN is a useful little freebie that does exactly as it's advertised to do: It swiftly corrects architectural perspective distortion. This sort of distortion is common in photos of buildings, when your perspective from ground level results in converting lines in a photograph.

Just fire up the program, load a file, and click "Automatic correction." You see one version of the corrected photo the left, and a version with correction lines superimposed on the right. If you don't like what you see, you can click individual lines on the right-hand version to turn off selected corrections, or just click the Re-optimize button for another try. Still not happy? Click "Adjust correction" to fine-tune the settings. When you're happy with the results, either select File, Save As to choose your own name, or File, Save Results to automatically save a version with "ShiftN" added to the file name. Alternatively, you could click "Save and exit."

You could use an image editing program like Corel Paint Shop Pro or Adobe Photoshop to correct perspective distortion yourself, but that is relatively tricky to accomplish. And you have the added step of needing to crop your photo afterward, since these fixes invariably warp the photo out of its rectangular shape. ShiftN not only fixes the distortion, but it also handles the cropping for you.

ShiftN should be in any casual photographer's toolbox. It's very simple to use and produces nice results.
