| LIGHTING TEST #1 |

 

“Anytime you mix lighting sources, it’s going to make it hard to find your white balance,”

- videographer Margaret Kurniawan

The "Colombus" of the day: White Balance.

These photos were taken on a gloomy night, in Zoe's room, we asked her if she could test on her iPhone if the camera is good enough to replace a professional camera - not that we didn't want one, but the school instead can not provide us with any equipment.

Right after we asked her to reduce the light intensity and try to play with the light, a funny phenomenon happened. At first, we thought that the light had a color setting and tried to find one, however, when we asked the teacher, we received a new aspect of thought: an effect of the camera. 

Something called White Balance. 

According to Adobe, "White balance refers to the color temperature at which white objects on film actually look white. But it's not just about the appearance of white; all the colors in your shot are determined by how you set your white balance." White balance can be fixed by choosing different lighting situations such as daylight, tungsten (indoor light), etc. But in our situation, something else is affecting the lighting but the temperature: the small lights. Even when the room obtains more light sources, this effect did not change (one thing to note is that the room temperature is at the same level).

So why is that?

The rule-of-thumb. The following table is a rule-of-thumb guide to the correlated color temperature of some common light sources:

Further study led me to blackbodies - which is something I do not need to care about because of light sources such as daylight and tungsten bulbs closely mimic the distribution of light created by blackbodies, therefore our phone automatically balanced it out. Mobile phones these days have something to call AWB - Automatic White Balance which contains a lot of preset white balance.

So we have something else to focus on when to film so that the product will not be affected by this effect while also understanding how to deal with this if things happen.
