Fill flash is a technique in photography where a photographer uses a flash to fill in shadows and add light to a subject. This technique is commonly

used in outdoor photography, especially when the sun is behind the subject, creating harsh shadows on the face or body. By using a fill flash, the

photographer can balance the light and make the subject appear more evenly lit, resulting in a more pleasing and natural-looking image. Fill flash

can also be used in low-light situations to add a pop of light to the subject and make them stand out more in the photo. To use fill flash, the

photographer sets the flash to a lower power setting and adjusts the camera’s exposure to balance the ambient light and the flash output.
