Has anyone had any experience shooting long exposures with the ist D/DS series of cameras? When I say long exposure - I mean around 1-2 hours at minimum, like trying to capture star trails

I ask because this: http://www.filefactory.com/file/cf6620/ [8mb jpg]

is the result I got from a 1 hour exposure, shooting RAW with noise reduction on. Im running firmware 2.00 so there shouldnt be any problem. If i shoot with the NR off, i get a similiar effect but its all pink.

Any ideas?

1 hour is a REAL long time.... even for film.

That you are going t get noise is no real surprise.


Then again there are neat tools like NEAT IMAGE.

damn, I don't think that's healthy for your sensor...


You can capture stars with a far shorter exposure...60 to 120 seconds maybe?

If you are planning such a long exposure, make sure you have a fresh set of batteries that will keep the camera operational during that time!!

You don't need to register, you just click "Download for free with FileFactory Basic"

As for the picture... I have no idea whats going on, but I guess that length of time is just too much for the sensor.
