Vog Hazards Gallery
The best way to picture vog is to compare voggy conditions with times when the vog is not present.
Below is a series of photos that illustrate the differences, both in visibility, and in effect on plants.

Vog can sometimes be harmful to plants. Native species like uluhe and ohia have adapted to SO2-rich gases, but exotic plants, such as ginger and tibucinia, are susceptible to damage.
Photo above: Leaves of tibouchina and ginger on 27 August 2007, two days after calm winds saturated the Volcano area in dense vog. Photos below show details of leaves.
