Lesson 13 Complementary Color Gels

This photograph was the inspiration to try to replicate the lighting.  Shannon found two gels that were almost complimentary and we gave it a try.  To see and interactive complementary color wheel go here.
Here is an interesting article about the use of color gels for the stage.

Lesson 10 High Speed Sync

Here is an article that explains Canon High-Speed Sync.  Here is a diagram from the article.
Here is a good video explaining high-speed sync.  He uses the 580EXII with the Pocket Wizard Mini TT1 and Flex TT5 which we have in the cage.  During class we are using the Canon ST-E3-RT and Canon 600EX speedlite which has radio control built in. At 1:03 is an explanation of 1st and 2nd curtain and at 3:30 is an demonstration of how the system works.

Lesson 6 Bare Bulb and the Quantum Flash T4D

Alfred Eisenstaedt using a bare light bulb to fill shadows in the 1940's

Brassai worked hard at the technical aspects of his photography and believed it was important in his efforts to show his subjects clearly.  The flash bulb had just been made commerically available in 1931 and it was perfect solution for shooting in crowded clubs. .
This is an early flashbulb holder with an irremovable reflector with a Sashalite flash bulb
.  The bulb contained aluminum foil in 2 atmospheres of pure oxygen that was ignited with 2 D cell batteries.   Even though it was a hugh bulb it didn't put out nearly as much light as flash powder.
 


 Before the release of the flashbulb, he was using flash powder outdoors at night to create supplemental light. Flash powder was essentially a control explosion of Magnesium and created noise, soot and light. I am sure soot and noise would not be welcome in the kind of clubs he was photographing in.
