    This was the best out of all of them. I was wondering how I could stop all the lights from looking like stars. I know most people like the star look but its everywhere in this pic.

    Try sacrifice a little bit depth of field and use a bigger aperture. star effect on lights are enhanced by small aperture. cool shot btw

    The spikes around the lights are called 'diffraction spikes' and are cause by the lens aperture blades.

    The wider the aperture used the shorter the diffraction spikes are.

    As far as the DoF, DOF gets depper the further away from the camera the focus point is. You used a 50 mm lens at f/10. According to an online DoF calculator, using a 50 mm lens at f/3.5 and a point of focus 2500 feet from the camera, the near DoF limit would be 115 feet from the camera and the far limit would be infinity. Even with your point of focus at 5000 feet the near DoF limit only increases to 120 feet. The far DoF limit will stay at infinity.

    The white balance in you photo needs adjusting.

    Wow i thought the star effect was only possible with one of those filters! Good to know! Nice shot but don't like the crop. Especially at the bottom it leaves me wanting to see more.

    Star shapes are made with straight blade apertures I think.
    Rounded apertures can't do them.

    You would have to use a larger aperture.

    They can but they are shaped different. Any lens will do this.

    Lol the bottom was just 50ft tall pine trees so all you would see is black silhouettes. I either had too much black trees or too much black sky. Thats the downside of living in heavily wooded areas. 2wheelphoto thats prince george in canada. And congrats on becoming a mod kmh.

    I was also struggling with the white balance. What do you suggest I use? I tried tungsten and everything looked too blue. This was the closest I could get to the actual picture.

    There are 2 main light types in your photo. Low pressure sodium vapor, the orangish-yellow lights, and mercury vapor lights, the bluish-green lights.
