1/25th, f/3.3, ISO 64
At the lowest sensitivity setting the picture is smooth and noise free, but the lousy weather means a dull low-contrast picture.
1/40th, f/3.3, ISO 100
At 100 ISO the picture is still smooth and free of image noise.
1/80th, f/3.3, ISO 200
Up one stop to 200 ISO and the picture is still very good, although there is a hint of colour distortion creeping in, with green and red splotches.
1/160th, f/3.3, ISO 400
At 400 ISO there is definitely some image noise visible, but the overall image quality is still good and the picture would print well.
1/250th, f/3.3, ISO 800
At 800 ISO the image noise is more severe and coarse-grained, and would show up on even a small print, although colour and contrast are still good.
1/100th, f/6.6, ISO 1600
At the maximum 1600 ISO the image noise is now very bad and the image quality is seriously degraded, with reduced contrast and colour saturation.
