Hi all, Excuse my noobness but I'm new to digital photography. I've been been trying to get that "misty" effect when shooting waterfalls by using a long exposure time. However, when I try it out I end up with shots that are harshly overexposed. Here are a few examples: 25mm, f/25, 1" s, iso 100 18mm, f/18, 1"s, iso 100 Does anyone have any tips on how I can achieve the effect properly? Thanks in advance.
