The black metal frame of a candle lit nativity scene was a Christmas present in 2019. It contains a nightlight holder and the light from that holder shines over the manger/crib. To light the scene further I have used a larger multicoloured candle. The rainbow colours of this candle light the whole area around the nativity scene. The wall behind the candles also takes on a different glow, depending upon how dark it is.
Some of the images are captured with the electric light on, others are in differing degrees of darkness. Early one evening the candle produced a purple glow, subsequently the glow became more orange and red. I have also use the lens ball on the nativity scene. In this case I am not really sure whether it adds or detracts from the images. however, its practice at using it! Photoshop spins the sphere through 180 degrees. Again more practice!

Experimentation
The whole process has been one of experimentation. I have had the nativity scene with and without electric light, with and without the lens ball. The lens ball has been moved backwards and forwards. A freezer in our extension was a convenient place to capture these images. However its white lid caused unwanted reflections. Towels and other material enabled me to avoid the reflections.
