Okay so a while ago we had to take pictured for my computer class, using different settings, so i was taking this one picture with a slower shutter speed, and for some reason, it turned out like this... i dont get it. everything should be blurred! not just teh phone!! explain you photographers! please?!

 

 

 

Because the phone is the only one reflecting light.

It must be on long exposure.

Because the phone is the only one reflecting light.

 

If the phone was the only one reflecting light, then the rest of the picture would be perfectly black. Think in terms of raytracing. How were you moving your hand? As in, were you moving the whole thing or were you just moving the fingers holding the phone, making it the only thing moving enough to get a blurred exposure?

 

 

 

Also, your hands do look slightly blurry- Yet due to the laws of DoF it should be perfectly in focus. That may be a small motion blur.

i was moving my whole hand and phone

Strange. I can't really tell why that would happen, other than if if your camera compiles longer exposures in some funny way.

The phone is like a mirror which messes up the light, probably what Pat was trying to explain.

I think your camera simply saw the moving light so it recorded that, and it only recorded your hand how it behaved on that moment. Your hand didnt get blurred because it doesnt reflect as much light as the phone did.

 

 

 

Something like that, I think. :|

As stated above, it's likely to be an issue with the light. I suggest a longer exposure, and slower but longer strokes of movement. :

edit: nvm.

Alright, thanks guys! just thought it was a very interesting photo!
