Candle photographs usually benefit from a simple composition with no distracting background elements.
Adding other objects to your scene can help give context to the candle, and tell a bit more of a story. When arranging your objects, arrange them so that they cast long, interesting shadows through your scene. This will add interest and create a sense of depth in your photo.
TURN OFF THE LIGHTS
It amazes me how many people photograph candles in full daylight. Doing so usually overpowers any light from the candle’s flame itself, making it virtually invisible. It also completely destroys the warm, intimate glow you get from your candle, which is one of the things that can really create an interesting atmosphere.
ENHANCE THE WARMTH
Candle photos usually look best when they convey a strong sense of warmth and cosiness. Unfortunately, the orange light that they produce can often confuse your camera’s automatic white balance, causing it to overcompensate and remove the warm feeling altogether in an attempt to capture what it sees as the “correct” colours.
