Somerset House in London taken with a 16mm wide-angle lens How to Use Lens Correction in Lightroom You may like the effect of wide-angle distortions. But for a realistic look, you will want to correct lens distortions. We know what we are seeing is not reality, but it is fun. Using a wide-angle lens and shooting close to your subject creates a humorous effect. For instance, lens distortion is the whole point of a fish-eye lens. You may like the look created by your lens. You can choose to correct lens distortions or not. Adobe makes a lens profile correction to adjust for the distortions. Manufacturers document distortions created by each lens. But you do not need to figure it out yourself.
The physics of lens distortion can be complicated. You are more likely to see vignetting at wide apertures where the lens barrel blocks some of the light. The light on the edge of your frame has further to travel than light in the centre. Vignetting is caused by elements in your lens blocking light as it travels to your sensor. Lenses may darken the edges of your frame. Purple fringing on edges of church window removed in Lightroom You may see chromatic aberration at wide apertures and the edges of your frame. This is called ‘color fringing’ or ‘purple fringing’. When the colours do not align on the same focal plane, the result is purple or green edges in parts of your image. Colours pass through the glass at different wavelengths. Exaggerated barrel and pincushion distortionsĬhromatic aberration happens when lenses have difficulty processing colours. This is where straight lines seem to pinch inward from the centre. Telephoto lenses are most likely to have pincushion distortion. Straight lines appear to curve like they are wrapping around a barrel. Barrel distortion often occurs with wide-angle lenses. Barrel and pincushion distortion are two of the most common in camera lenses. Every lens has slight optical distortion. Optical distortions make straight lines bow or curve. Common issues are optical distortions, chromatic aberration, and vignetting. Post-processing programs like Lightroom can get rid of the rest. Over the years, lens manufacturers have reduced a lot of the flaws. These are created when the glass is ground, and the lens is put together.
