I was shooting the Tracy High varsity football game last Friday night when journalism teacher Wayne Thallander was showing off his latest piece of photo equipment. It is a fresnel lens attachment for his electronic flash.
Using the same concept that allows lighthouse to send a beam of light miles out to sea the attachment focus the flash power to illuminate a subject much further away than normal.
It seems to work ok, I wanted to try to bounce the light off a low flying Russian spy satellite but I didn’t want to start another war.
