Photographing fireworks on New Years in cold climates

July 4th fireworks in PhiladelphiaNew Years comes this Saturday, and with it, across much of the U.S. like across much of the globe, that means fireworks displays. In much of the U.S., Canada, Europe and Asia, that also means cold weather.

Photographing fireworks takes planning and knowledge at anytime, but cold weather makes photographing fireworks even more challenging as we have to contend with both the cold which will sap the strength strength of your battery and can cause condensation to form on and in your camera and lens. Dressing for cold weather can also make it more difficult to handle your camera.

Beware: a new study shows that tobacco smoke and vaping aerosols kill eye cells

A new study shows that smoking potentially damages the eyes more than anyone thought, as smoking can kill the eye's corneal cells.

Graphic: Anatomy of the Human EyeTobacco use has been scientifically linked as a cause of heart disease, stroke, chronic pulmonary disease and lung cancer. The data on smoking and those diseases is undeniable. The deadly health effects of tobacco have been well known since 1964, when Luther L. Terry, M.D., then Surgeon General of the U.S., released the first report of the Surgeon General's Advisory Committee on Smoking and Health.

In addition to those diseases, smoking can impair human color vision acuity, an extremely serious problem for photographers and visual artists.

This past September, Scientific Reports, an online peer-reviewed journal published by Nature Portfolio, published a new study about smoking and vision. “Cigarette smoke extract and heated tobacco products promote ferritin cleavage and iron accumulation in human corneal epithelial cells,” by Wataru Otsu, PhD, DVM, et. al. from the Gifu Pharmaceutical University, Gifu, Japan. The study details the alarming problem that cigarette smoke and baked tobacco aerosols from vaping devices can kill the eye's corneal cells.

Even without this new information, for photographers and visual artists or for anyone who needs their eyes in top working order, we already knew that the effects of smoking on vision is frightening.
