The problem in this picture is that only one side of the creek is lit while another is in shadow. High banks don't help either. Plus I used a crappy kit lens which gives bad colors. Polarizing filter helped a little.
I barely use my kit lens 18-55 mm because you know, it's not that good. But since I don't have anything else wider then 35 mm, I decided to use it yesterday with polarizing filter. It's not that bad I think.
