I am still fairly new in using my digital camera. I have a Pentax K100D. I currently have two digital lens. The big zoom lens is 80-300mm. Below are a two pictures, what I am I doing wrong, and how can I get the long zoom lens have better color? These pictures where taken at the same place, along the old Rock Island line in Missouri, which is being turned into a rail trail. What do I need to do to improve the color on the zoom lens?
