Hey,

Im going on a camping trip in two days, (away from the ambient light of town), and im thinking of doing star trail shots, but Im wondering if anyone can give any information about them...like, the aperature to use, and how long to leave the shutter open? I think there will be alot of 'long-lens-moon-photos', and shots from the city of traffic light lines, and exposed buildings with lights on, or shots of the freeway. There will be a few star trails i think, in this challenge, but Im trying to do something that there will be less of. If i can't do any star trails easily, then I'll just bring my small Canon Powershot S200 to take simple snaps for the yearbook, but if i get some good info, then i'll bring along my Penguin case and my Rebel.

Thanks in advance for any ideas of night shots or help with my star trail idea.

I might be able to help you , but I don't think you need advice really. You said it yourself, aperture and shutter speed. The larger the aperture F2.8 for example, the more light let into your lens. The slower the shutter the more light your camera will capture. Make the adjustments depending on what you want to shoot, how much light you have to work with and the Depth of Field.

Hey,

I did this before, and it's not as simple as it sounds though, unfortunately, if i set my aperature to the lowest, say f/3.5, then I can't leave the camera for too long or for too short, because, leaving it too long makes the image overexposed, and not leaving it out long enough, ends up with an underexposed image. The process is mathematical and complex. I need someone who did this before to help me with the details.

Thanks in advance,

Simon

I think the use of a tripod might also help for those night shots to prevent camera shake.
