The images was shot on a Canon 350D on may 10th, around 21:10 (according to camera settings, which is probably wintertime so add 1 hour).
The lense used was a 17-70mm, which is a more or less common zoom lense for this camera. Iso speed on all shots was 1600, which along with the slight underexposure of - 1/3 could account for the noise.

The fastets shutterspeed used without the flash was 0.3 secs, which is quite a long time. I've never met anyone who could hold a camera still enough for a longer time than 1/60th of a sec to make a sharp or unshaken image. Normally 1/125th is the optimal to ensure no shake on a standart lense. If you shoot on fx. a 120 mm you probably need 1/250th of a sec, etc etc.
Ofcourse given the lack of light the need of decreased shutterspeed and increased ISO was a natural.
Aperture varied from 3.5 to 4.5.

Images 0353 and 0354 (the ones where the streaking is downwards left to right) was shot on 1 sec... that's quite a lot and I'm not surprised by the streaking. Even if the objects were stationary you'd get this streaking with a nonsteady hand. The images were taken 3 secs apart.

Images 0356 and 0357 (the ones where the streaking forms a u or v) was shot on 0.8 sec... again quite a long time. Those two images were taken 7 secs apart.

Image 0366 (the one with the longest streak) was also shot on 0.8 sec. This however was shot at 70mm. Longer focal length requires faster exposure time in order to get a sharp image. So a 0.8 on 44mm compared to 70mm is very different. The same amount of shake in both shots would look more dramatic on 70mm than on 44mm.

In both mentioned cases autofocus was not enabled.

Ok I have Canon Rebel too (XTi aka 400D)..after watching some of yours pics i can say this ..i suspected the ISO was high on the shots because of the glow in the sky and sorroundings.. (iso 1600 very high)...so unless it was very dark i dont know why your friend use a very High ISO counting for making the shots...RAW is excellent it keeps a lof of the data.

Using the ISO so high and on Manual mode made the pics look blurred (any shake at that high iso even with speed shutter very fast) can still show the trace (buildings blurred)... So only one thing...nice catch..bad choice of setting for taking the photos!!!.. even if the objects didnt move at that high speed (like you are saying or thats what i did understand) any shake would make the Objects look blurred and like in motion with that Iso.

More Higher the ISO you use, more Glowing and Pixelated the image will be, and this what happens on this pictures, high glow, pixelated (not so sharp for a i think its a 8 megapixel cam) and on top of that any shake of your hand (not using a tripod) would surely induce blurring (like in all the photos)... and wala thats what you get on your pics... about what did you catch..looks UFO's to me.. i just hope nex time you use automatic mode for that...

Well thats what i see on your pics..anyway good luck and next time if your friends see another UFO use Automatic mode...this will save you a lot of pain...using ISO's is not the best way with this type of things (makes thing messy unless you use a tripod).....

Hope this helps....

Try some UFO knowledge on the Tesla side.

Just because your government is ignorant of Tesla mechanics to
generate such a craft, you don't have to board the train of
their balloon and reflection excuses.

The Illuminati gravy train has everyone on board in the denial
of Tesla.

These are some of the best UFO photos I have ever seen. Great resolution, and the large file they are sequenced... good job!

one of our board members recently posted the comment that there were 2 more sightings of some objects, both on the 10th of May 2008

over Magdeburg/Germany
over Hamburg/Germany

really interesting, can that be on the same day at least 3 German Cities? The weekend befor also at least one sighting. Witnesses say the could not identify them as balloons or laterns. And me eather like I reported.

that´s all what is actually known. I think he is in touch with some flightcontrols and skywatcher communities, so I belive he will bring up soon some more details. Hopefully.

cheers

Appears to me that the noise was natural at a higher ISO setting i.e. 800-1,600 ISO which will give grain and also one tends to use higher ISO'S when shooting in lower lit conditions such as this-i, as a photographer say that this is natural high ISO noise from the camera.Which camera was used for these shots by the way?Just curious.

next Sighting:

12th May 2008 ca. 2:30 CET
over Hannover/Germany

25-30 Light-Objects orange coloured
Objects were flying with high speed/velocity

In a quit area were planes do not fly very often.
No sounds.

I am not very good at this and I used the photos posted but I wanted to see if there were some kind of movement of the "objects" in a GIF animation .. I might have some of the photos out of order but what do you guys think ?

the movement looks really similar to the sigthing I had

The nice thing about the animation is also that the ufo's were moving at least at that speed.

The reason the pictures are blurry is because the shutter speed is slowed down in darker situations to allow more light in. If he was to take the pictures with a fast shutter speed, the pictures would be really underexposed, and the pictures would probably be completely black. Also the noise is the result of a higher ISO, which is the light sensitivity.

Sorry if this has been posted already, just trying to explain the basics.

definately, I agreee with you, i had the same feeling about when i was thought about my sighting how the flightmovements were...
and exactly that´s it.

And they were flying at a similar height over the roof...

I guess the building had no more than 4-5 floors.

One question:

you said noise? Is there a video available or what?
I haven´t seen anything yet.

thank´s

Noise is a term for visual artefacts on the shot, mainly due to adverse lighting conditions. Not noise in the aural sense.
