This is actually not about aviation but digital photography in general, anyway. I have a problem with a disturbing (but sometimes nice) "effect" that confuses me, and I would like to have some things sorted out. Basically it ruins night shots, it looks like a ghost have been running around in front of the camera with a flash light.
Now this might be something that probably everyone knows about except me, I have only been shooting digital for three months but have a couple of hundred regular SLR night shots behind be and this have never occurred before.
Now to the examples.
This picture is the first one I have seen the effect on, my girlfriend took it in Egypt, and neither she or me can explain what causes the light-lines in the picture (nope not a single airplane passing by). 3 second exposure and the camera was not moved.
And tonight I was out taking some "artsy" night pictures at my former high school and I got this, also here the camera was not moved during the 13 second exposure (ISO 50, on every). I find it very strange, like if an invisible man was runing around with some lights
(Well now I am silly).
On the other hand I took three other perfectly normal shots in the are just within minutes.
Can somebody explain what causes the effect ? Is it some kind of "bug" because I do not have a fancy DSLR
? Or is it just something that I do wrong. Please share your opinion / experience on the subject, and maybe even some examples.
By the way, please do not complain about the quality of the picture I was just playing around
