Balancing Warm Lighting
By using a color filter on your Speedlight, you can change the mood by adding a color cast to the scene. Lighting brings a whole new element to the enjoyment of photography.
By attaching a warm color filter to the Speedlight, you can simulate candlelight to capture the mood of the moment.
Color compensation filters and color filters are available for Speedlights. If you want to color the scene using an incandescent filter, set the camera's white balance to direct sunlight.
