Our first case study was submitted by our regular visitor Dennis, who lives in Singapore. Here is the description of his problem:
Hi Nasim, I have tried night shots using 35mm f/1.8G. It is a landscape shot with river reflecting street lamps. I do it handheld, aperture mode, f1.8, shutter 1/5sec, ISO 1600. Strangely despite a dark black sky, the shot came out reddish sky and the center focus point have some reflected light that shouldn’t be there. I tried to shoot other night shots on sky, it appeared to have this reflected light. The pattern is random, depends on what I shoot. I don’t understand why. Do I have to take out the UV filter attached on it? I have read through these tips, but couldn’t understand what causes this to happen. Yours look sharp!
Dennis sent me the following picture as an example, which was taken in a public park in Singapore:
Here are my comments on the photo, along with the solution to the problem:
