The Tyndall scattering, also know as Tyndall effect, is a effect that after a beam of light goes through the gel a bright path can be observed from the vertical direction of the incident light. This effect will be achieved by PS skills in the course.
Step 6, Press the Ctrl, alt and e buttons at the same time to cover the former layer without erasing it. Click “Gaussian Blur” and then change the layer overlay to “Screen” and transparency to twenty percent. Next add a curve adjustment layer to brighten the light house.
