One of the banes of using zoom-lenses is that of barrel-distortion at wide angles (especially for the cheaper/budget lenses). I came across a link to two interesting free software tools to correct these distortions: RadCor and PTLens (upon which RadCor is based). Digging out a shot that was previously badly affected by barrel-distortion, I tried out RadCor with impressive results. Additional Photoshop tinkering that led to the above image: Channel Mixer tweaking for the monochrome / IR look, followed by adding Noise for a slightly grainy look. Taken more than a year ago outside the ESPRIT shop at Raffles City.
