D90 Automatically Moves While Bracketing

**Lrk** · 06-03-2010 04:45 AM

While i was working on a HDR timelapse i noticed something strange.
I was using the 3 step bracketing (since the D90 doesn't have a firmware update to a 5-step as far as i know). The D90 was mounted on a very firm and stable tripod. The first of the 3 shots (under) of each set was always pointed slightly downwards, the other 2 were perfectly aligned. After taking the 3rd shot it would immediately move back down again even if the next set was several seconds away.
It's not a big problem, but i can't find the cause. I tried to look at the camera when it was taking the shots, but it doesn't seem to move.
I drew a line were the top of the chimney was suppose to be.

OfftopicPS: Yeah, i noticed the buildings were underexposed, so i changed it a little in the next sets.

My T1i did a very similar thing with bracketing. The third shot of bracketing was off by a hair and usually out of focus.

The EXIF for the 3 images all show 1/4000, f/11, ISO 200, -2EV, Manual mode, Matrix metering.

Something doesn't compute.

I loaded them as layers in Photoshop, added a 4th for the line (so it's in the same place) and then exported the layers manually. It's probably from there.

AF or MF? I'm guessing AF and the image will change just slightly when focus changes.

I'll bet you had it on AF and AI Servo (or whatever the Nikon equivalent is called)... Just flip to MF for autobracket shots. Problem solved!

Robert means turn VR off.

**robertwsimpson** · 06-03-2010 09:35 AM

No, I'm pretty sure I meant turn AF off. Turning VR off would also be a good idea... I assume everyone does that when using a tripod.

Good call.

I may be noobish, but i'm not that noobish. It was on manual focus. But VR was on. I'll give it a test run tomorrow and let you know. Thanks.

Focus will not MOVE an object that's why I thought Rob meant VR. It may bring a blurry object into focus therefore moving the edge of the object closer to the object's center but that building was in focus to begin with.

Do an experiment. The view through my lenses changes slightly when focusing. I'll bet yours do too.

which lens? because iknow that my 105mm micro will breathe a little, and may change the positioningly slightly when in AF.

VR on? Can you try it again with VR off. The camera is on a tripod and you need to turn the VR off.

**epp_b** · 06-03-2010 08:56 PM

But VR was on.

That'll do it. VR and tripods compete against eachother. You should only ever have VR on when you need it.
