I don't even know what you call these things. They exist in wetlands and are up to ten feet tall or more. I took this photo a week or two ago. I usually touch up a photo slightly in Photoshop, even if it's just to sharpen it a bit. In this case I boosted the contrast, sharpened it, and increased the saturation quite a bit to bring out the yellow colour in particular.
Sometimes, you want to record how a scene looked, but, other times, you want to record the scene as you wish it had looked.
