Hi All:

I have read in Photo magazine reviews on all sorts of Nikon DSLRs about ISO speed not affecting graininess. Well, this weekend I went late afternoon hiking, found an old sugar mill and other various objects as still subjects. Unfortunately, from some other shot I was testing I had it on ISO 1600 and forgot to change it back before the day's shooting.

In the view finder on the D40X it all looked fine, but that is tiny, and so I moved on and took more pics. In PS, the moment it got to full screen size it was just a pile of grain! Now from reading the reviews on many of these cameras, they say things like, "And at ISO 1600, no graininess and still sharp as ever!" I have seen this sort of review many times, but it baffles me.

What on earth are they referring to? Something I am not doing right?

Even long exposures on ISO 100 get graininess..or is it something I am doing wrong? I know in film this was always the case but these reviewers saying that it is not grainy and still sharp in digital like somehow this was all overcome...makes me wonder.

Here is just one of the pics.

Thanks,
Zukester
