Weekly review

This week we have been learning about the types of lighting used for artificial lighting. I gained a good understanding of the strobe of light and this was a demonstration I really enjoyed, with the props coming from my teacher.

Stroboscopic effect

When a gas discharge lamp is used as the illumination light source, if the illuminated object is in a rotating state, and the rotating frequency is just an integral multiple of the power frequency, the rotating object looks as if it is not rotating. Under the illumination of light that changes at a certain frequency, the observed movement of the object shows a phenomenon that is different from its actual movement, which is called the stroboscopic effect.

Videos about the effect

In the first video I shot, you can see the little black grids appear to be relatively static for a period of time. The second video doesn’t seem to be very successful, but I really enjoyed the wonderful gradient of colour that came with the rotation of the prop.
