When i first started using dslr 2 mths ago..normally when i shoot long exposure shots, it will display the photo immediately after the designated no. of sec that i chose, but however recently i realised there is this display (see pic) after i taken the shot. What does the "Busy" means and why is it sometimes like that?

Many thanks for whoever kind souls who can help...

did you turn your long exposure noise reduction on?

for long exposure, if you turn the noise reduction on, then the noise reduction will operate as long as the time used to take the photograph.

it might be that your usual long exposures are pretty short. i think for my dslr (k20d), the noise reduction will kick in for any exposure longer than 15 seconds.

yours should be able to turn off if you don't want to wait, but please remember to do some form of cleaning up later on when you pp photo.

Read the manual bro, under custom function:

1. Whenever you activate Long exposure noise reduction
2. After the pic is taken, it will process the cleaning using the same amount of time as the exposure.

At least you get a BUSY on the screen. My D90 do not even show that. :bsmilie:

But really, LE NR is actually very good. Problem is, if your exposure is a 5 min long exposure, waaa the wait can kill you. And remember to turn off LE NR if you are doing 30 min star trails.... :bsmilie:

Thats the issue man...if you take sunset or sun rise pics with LE NR, by the time you take 2nd shot you already missed it!

you don't take sunset or rise photo with long exposure when the sun is visible, 1st, exposure not permit, 2nd, if you really do, the sun will be out of shape too due the earth rotation.

yes, it show "job nr" in top panel and in the view finder.
Yea it does show on the LCD display for D90. I just tried it last night and got the "JOB NR" on the LCD. thought something went wrong. then i remembered i turned on the LE NR.

i'm getting my b+w nd110 today!! Will try LE in daytime...well not exactly shooting the sun, but rather nice skyline when the sun is setting or rising.

I did a 40 min for mine :bsmilie:
I get blown skies after 8s on base ISO of 200 at f/2. ;p

Let's see how many stops down I have to go for a 40min exposure..

15, 30, 1m, 2m, 4m, 8m, 16m, 32m. About 8.5 stops. I need to stop down to f/22 and use an ND2x or f/11 with ND8x?!?

you need a very dark moonless cloudless night sky and far far away from street lamp building lights etc...... if you can find it in SG :bsmilie:

anyway, think some people use stacking technique for overcoming some issue of extreme long exposure

When it comes to star trails, I love the reciprocity failure of film.

Ya, my ang mo friends all hike to some mountain in the middle of nowhere, set up start the shutter, and lie in the dark and wait. That's why I say need a lot of patience.
