Photographing Yosemite’s Firefalls with the SIGMA 60-600mm Sports Lens » 2019_0222_Sigma60600_FireFalls_IMG_3342_2000px
Yosemite’s Horsetail Falls seen prior to becoming a spectacular reddish color, in Yosemite National Park on Friday, Feb. 22, 2019. This photo was taken with the SIGMA 60-600mm F4.5-6.3 DG OS HSM Sports lens set at 60mm. This effect only happens around mid February if conditions are right. There has to be enough snow at the top of El Capitan, it has to be just warm enough for some of the snow to begin melting, the sun has to set at just the right angle and there has to be clear western sky so that sunlight illuminates the falls.
