Low power [Explored]

Unmatched light sources from across the years.

 

Low power applied to a battered, decades old 12V car bulb and a modern day 3.2V 1W warm white surface mount LED.

 

Low power used so you can see some of the the light source detail, not just a blinding white. This causes the filament bulb to glow a nice orange and the LED a greenish hue.

 

William David Coolidge invented a tungsten filament for an incandescent bulb in 1910.

 

Dr. Jürgen Schneider created a white LED light source in 1995.

 

A bit of a palaver getting both powered and in focus at the same time. A 6 image focus stack helped show more detail, especially of the filament coil. I used my trusty 85mm f/1.4 Samyang stopped down quite a bit. Additional lighting all LED. See my somewhat chaotic setup image below.
