There are times when working on the computer does not come easily. I have lots of props lying around and sometimes it is fun to play – the bug is plastic so no need to send pest control over. There was a sort of serious side to this though, I wanted to run a few tests on the higher ISO settings of my Nikon d40x to see the ISO difference between it and a couple of point and shoot cameras.
I am the first to see the pluses of point and shoots but quality shots at ISO’s above 400 is not generally one of them. I don’t actually have a problem with noise and think that it can add something to an image but there is a type of noise that comes with cramming to many pixels onto a sensor that is just downright ugly – a lot of very harsh looking artifacts that look nothing like the noise on larger or less crowded sensors.
The best way to make these point and shoot images usable that I have found is to use the noise filter in light room to lose the really sharp edges of the noise then, ironically, to add some grain back in using the add grain filter. The result is passable but nothing like a high ISO photograph taken with even a small sensor DSLR.
This photograph was taken with the ISO set on High which is 3200 and a higher resolution version is here.
