    Types of lens distortion

     

    Below are examples of common types of lens distortion illustrating how they affect your composition.

    Barrel Distortion

    Barrel Distortion

    Barrel distortion creates an image in which lines bow outwards towards the edges – making rectangles appear barrel-shaped.

    Pincushion Distortion

    Pincushion Distortion

    Pincushion distortion makes lines appear to bend inwards towards the centre – making rectangles appear like the outlines of a pincushion.

     

    Chromatic Aberration

    Chromatic Aberration

    Chromatic aberration (or achromatism) is usually seen through the colour fringing it creates on lines and edges in the image.

     

    Vignetting

    Vignetting

    All lenses create an image that’s darker at the edges than in the centre – this is known as vignetting, and can be used as a stylistic device.

     

    No Distortion

    No lens distortion

    No lens distortion, where lines are as straight as in reality. There’s no darkening at the edges, and all the colours are focused at the same point.
