Assignment 10 Canon Transmitter ST-E3=RT and 600EX-RT Flash

Work in Groups in the Studio for this Assignment.  The group will produce 1 of each pictures in the assignment.  Rotated jobs so everyone gets to set the St-E3-RT transmitter.

1.  Make a portrait using the ST-E3 as the Master and a single or multiple 600EXs as the slave A on ETTL and modify the light coming from the 600EX to a broad source of light.  You can use diffusion, umbrella, soft box or bouncing off a wall or card.

2.  Make a portrait using ETTL ratio mode, the 600EX used as direct light and setup like our Rembrandt lighting with the clamp lights.  Each 600EX should be set on ETTL and each with a different letter A,B and C.  A is the Key light, B is the Fill light and C is the background light.  Set the ratio between A and B to 4:1 and set the background light C manually until you like what you see.

3.  AM class's demonstration was different than PM class's demonstration.  You can use either method.

AM Demo:  Make a portrait using the Gr mode and the same light set up as 2.  Set the Master to GR and set A, B and C to M.   The three slaves will set themselves to M after the 1st shot.  Use the ST-E3-RT to adjust the setting manually to get the same results and you did in #2.

PM Demo:  Make a portrait using the M mode and the same light set up as 2.  Set the Master to M and ratio to A:B C.  The three slaves will set themselves to M after the 1st shot.  Use the ST-E3-RT to adjust the setting manually to get the same results and you did in #2.

4.  Make a portrait using the Group mode and the same setup as 2.  Set the Master on GR and set A to ETTL, B to M and C to Ext.A  A or the Key light is set automatically but the fill will have to be adjusted manually.  The Ext.A will render what every it is pointed at to 18% grey.

Write down all the settings you end up with for each shot.  Exposure, exposure compensation(if any), Mode, setting for A, B and C.
