The task: photograph a stream. Are you photographing the stream in a landscape? Do you photograph the small waterfall in the back on the left with a long exposure time? Do you photograph the reeds at the edge of the stream? Do you photograph the water drops on the grasses at the edge of the stream? There is no right and wrong. Because every motif has an infinite number of image details and thus offers room for your creativity. Generally speaking, image detail is not a question of a good camera or an expensive lens. Your lens doesn't have a good zoom? Then move and get closer!
Sometimes a photo of a small thing can make a whole picture. Start to see.
