I looked in my Manual to my camera and could not find anything!? Well It with my D70 when i shoot long Exposure shots it like freezes up and it take like 1-3 min to get the image to show up. While it is processing it says JOB NR on the Control Pannel screen. I dont know if it is the Camera or the Card. Im using a CF SanDisk Ultra II 1gig Card. I dont recall this happening before but i have been dealing with it for about a month now. it does not hapen on regular shot just long exposure shots like... doing lightning... or night motion shots... and the 4th of july was bad to.... any ways thanks....sorry so winded.

I think that is what it displays when it's recording... if you take a 30 second exposure, it'll need about 30 seconds to record, which is why you're only seeing it for long exposures.

JOB NR is displayed while it's taking a black reference photo to reduct noise. if you take a 15 second exposure, it will show JOB NR for 15 seconds _after_ the shutter closes. it then takes the two exposures and uses the second reference to remove noise from the first...

you can turn noise reduction off in the menus and you'll not see this message... (but you'll get more noise...)

You most likely have long exposure noise reduction turned on. When it's on, the camera taes a second exposure (with the shutter closed) that's as long as the first. It then subtracts this "dark" exposure from the image, eliminating fixed-pattern noise. So if you take a 30-second exposure, it will take a total of 60 seconds, plus the write time.

I was going to say what Kirbic said. I turned the NR off on the 4th of July for the fireworks. it is still off. not sure it is worth the wait time having your camera totally disabled for up to an hour if you do a 30 min exp.. when you can do the same thing in adobe later in just a few seconds. and to be honest i didnt see much noise in the photos i took.

NIce!! Thank you !! I do recall now seeing that option and turning it on..... thanks. =)

so during this time is it bad to move the camera..... ex. if i take a 30 sec exp. and it take 60 sec to capture image is is bad to mave camera during the 60sec period??

edit: added ??

You can feel free to move the camera after the shutter has closed, ending the main exposure. On really long exposures (more than 10 minutes or so), you probably don't want to move the camera from one environment to another where there is a big temperature change. The "dark" exposure should be taken with the camera at the same temperature as the main exposure.
