Sometimes it is interesting to look for abstract colors and textures in nature. Especially if it a slow day to photograph wildlife. Also it helps you “see” more visually and notice more of what is around you. The more you look the more you will “see”. So I look for textures, patterns, shadows or anything that looks visually interesting. They can also come in handy for backgrounds in ebooks or art pieces. This is a photo of scum backed up on a small stream going under a walkway bridge at a local Natural Area. I liked the warm colors and textures.
