This was probably processed in a cheap, gimmicky program that makes an image appear cool or good to an amateur This is why you can increase and decrease the amount of halo buy changing strength, light smoothing and micro contrast. You are effectively allowing the software to either give you a large contrast definition area, making the HDR look stronger but also making halo's large The main cause of sharpening halos is using too high an amount or too large a radius. In general, I recommend radius < 1 and small amounts of sharpening. Remember that it is always possible to add more sharpening later, but adding too much early on is impossible to fix. Figure 13

  3. Lens flare is typically caused by a bright light source. The effect of lens flare can vary depending on the location of the light source in the frame.

Noise in photography is the arbitrary alteration of brightness and color in an image. The onset of this random variation generates what is called noiseor grain, which is basically formed by irregular pixels misrepresenting the luminance and tonality of the photograph. These pixels are visible to the eye due to their large size Resulting from close-but-not-quite-in-focus stars or shooting with a wide open aperture on a lens that isn't perfect — star halos, chromatic aberration, or blooming can ruin an otherwise beautiful night-sky image Tip 1: Try not to use a flash if possible-it is the number one cause of red-eye.
