When we visualize an idea come into a person's mind is always use of lighted light bulb. To further enhance this I imagine the great idea just like a balloon that can fly higher and stand out among the rest. Light bulb's shape just looks like a hot air balloon and it requires fire to produce hot air to lift up the balloon. A light bulb requires energy to light up for its function. By combining idea and balloon so this image came into my mind. I shot the light bulb separately and used my archive photos of hot air balloon festival to composite into this single image.
