Quoting Viv (Reply 1): A tripod and a long exposure.
I understand "tripod", but what do you mean by : "Long Exposure"
I know how to change the exposure and I also know that a long exposure will make the picture turn more white in the daytime, but how do you adjust you exposure time to work towards you benefit during the evening.

The reason why the longer exposures turn your photo white in the day time is because longer exposures leave the shutter open longer, thus allowing more light into the camera. When the camera stays open for too long during bright light the sensor just translates what it reads into whiteness (brightness). Since there is less light at night, of all kinds, longer shutter speeds allow more of that light into the camera and thus create a properly exposed image.

Quoting Sovietjet (Reply 5): I have a question about this too. How do I get the light streaks AND the plane? I have a picture on here of a long exposure but that night I just couldn't get the plane itself.
I have never shot that style before, I'm I am 99% sure this is what they are doing:
1) Set up a tripod for long exposures at the threshhold of the runway.
2) When you see an aircraft coming, start the exposure.
3) Get a large flash
4) When the aircraft is over your head, trigger the flash. The extra bright light will freeze the aircraft there in the frame, while still having the streaks.
The only thing that confuses me is how to work the flash in with the exposure settings, since I'm pretty sure you'll have to manually trigger the flash. I guess its just trial and error in order to get it right.
