The day before I left England my brother-in-law drove out to Chappell, Essex [I 
think it's Essex] to see an impressive railroad viaduct that spans a river 
valley. When I imported the images into LR I was dismayed to see that I had 
forgotten to reset the the ISO of 3200 I'd used indoors the evening before. To 
my surprise, though, the images are sharp and largely free of noise---well, to 
my eyes anyway.

I assumed that high ISO images, at least on my camera [*istDS], were always 
noisy. It was a bright day, and shots were taken with a fast shutter [1/750]. 
Is that the explanation? If so, what is the explanation? If not, what is the 
explanation?

Thanks,
