where do you live? Looks nice
Electromagnetism by the lighting causing distortion? No idea if that is possible, though.
[QUOTE=Sobek-;18779703]All of the exposures were identical in length and every single one except this one turned out OK... Would the CCD generate the necessary heat (noise) to cause this within 30 seconds? And why not in ANY other shot? :ohdear: That seems more likely to me...[/QUOTE] Well I can't explain that but it certainly is noise from the sensor. Perhaps some setting you've changed? Does your camera have a "long exposure noise reduction" setting?
just clone stamp them out.
It's noise. Try cooling down your camera next time. As silly as it sounds, those CCD chips are VERY intollerant about temperature.
Bad pixels on the sky.
Long shutter noise generation, it happens on any camera, including high end ones like mine. (Except the higher end you go, the less dots tend to appear. On my 7D it takes about 30 seconds just to accumullate like two dots) [b]Edit:[/b] Also suck my lightning pic biatch [IMG]http://farm4.static.flickr.com/3444/3921853624_de471203b4_o.jpg[/IMG] [b]Edit:[/b] PS From now on it would be better if you put these questions in Creationism Corner, we have a few photographers including myself in there.
Wow OP. That's some seriously bad noise, maybe even hot pixels... put lense cap on your lense, chuck it into bulb mode and crank your iso to max.. set for a 30 second exposure or more... If those little spots are there then you need to get in touch with the warranty section at nikon.. (If they are still there then your have hot pixels and they can map them out, if they aren't then it means you have a very ordinary camera) Oh wait, it only occured once.. Don't mind me.. Possibly electromagnetic intereference with the cameras sensor or electronics?
I have a nikon D60, and usually use it with the 35mm DX, and I never get noise like that, even at ISOs like 1600 with a 60 second exposure. I would get the normal softer noise and slight grain effect.
Spit on your lens
are you reflecting light from stars somehow? you might not have been able to see the stars but perhaps because it was a longer exposure the camera caught some of the light. just a guess. [editline]10:49AM[/editline] oh wait nevermind the dots are on the house too haha [editline]10:49AM[/editline] i'm going to go with static and dust particles then.
For a split second you were actually peering though the veil into an alternate universe.
Really? dead pixels?
