This was shot on a Bulb mode on DSLR. Meaning it was on slows shutter condition. People confuse why I need  to shot this in slow shutter speed ? Reason is simple, instead of having 1 same lighting/color, I can customize it with just my phone with color screen. There is a downside for it which is it won't able to take portrait shot as it only work on still object. In a nutshell, it's quite a new way to shot product maybe ?

Different color combination like Red and blue or purple and green.
