Colored dots appear in long exposure photographs when light sources such as streetlights, car headlights, or other artificial lights move across the frame during the exposure. The movement of these lights creates streaks or dots of color in the photograph, adding a dynamic and visually interesting element to the image. The longer the exposure, the more pronounced and colorful these dots can appear, creating a unique and artistic effect in the final photograph. **

Hair can appear differently in various lighting conditions due to the way light interacts with the hair strands. In bright natural light, hair may appear shiny and reflective, highlighting its natural color and texture. In dim or artificial lighting, hair may appear duller and less vibrant as the light is not as intense. Additionally, the direction of the light source can also affect how hair appears, with light shining directly on the hair making it appear more luminous compared to light coming from the side or behind. **

It's important to use a light touch and not overdo the editing to ensure the eyes still look natural and realistic. **
