Author 'Boucher Marc dit de Meilh' (Id 129192 ) : A blatant lack of light gives unexpected results. This raises the aperture of F/16 and an exposure time 15s inevitably gives a 'fuzzy' that might be interesting. Here, it was a candle lit in low light, the sensor aperture is left open for a long time. For a painter, I like the effect. Marc Boucher said Meilhan.
