Hello,
I got a strange problem with my F10. Whenever I try to use "night mode", I get stuck pixels. This get worse with an higher sensitivity or as the exposition time gets longer.
It has been the case for the following pictures:

I had to use a small software to remove this bad pixels.
Using this freeware: http://www.starzen.com/imaging/deadpixeltest.htm
and pictures which were taken in total darkness, I get following results:
With0.25s, no problem
With 3 s, 3 stuck pixels
With 8s, 47 pixels
With 15s, 250 pixels !
Well, these are not really unfunctional pixels, but I get some interpretation why they appear as white in the final picture. Fuji F10 do not use noise reduction substracting one "black" pictures with the one which has been taken -> these pixels are not removed by a post treatment.
I would be glad if someone could do the same test and share the results.
Take care,
Bob
