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

Work in Groups in the Studio for this Assignment.  Each member of the group should make a portrait using 3 Speedlites from different directions, controlled manually from the Transmitter attached to the camera which is also set on manual.  Each member of the group should make a unique lighting setup.  You can modify the light coming from the 600EX to a broad source of light by using diffusion, umbrella, soft box or bouncing off a wall or card. You can also use the light directly.

 Set the Master to GR and set A, B, C and D (Optional) to M.   The three slaves will set themselves to M after the test button on the transmitter is pressed.  Use the ST-E3-RT to adjust the setting manually.

Take a picture of the ambient light in the room at the f stop and shutter speed you will be using.  It should come out black. Post this picture with it's settings.

Post the the progression of images (ie one light, 2 lights, 3 lights etc) with final exposure for each shot (should all be the same)

I realize this is an ambitious assignment and that you might not have time for each member of the group to accomplish their own unique version.  Do the best you can and good luck.

There is a way to adjust the Speedlite setting on the 5DMIII.  Check out where to find Flash Function Settings in the 2 pages from the camera manual.  You might find it easier to make adjustments:

Assignment 9 Canon Dedicated Flash

Here is how to change the flash sync speed in Av mode:

Use direct flash on camera Aperature Priority (Av) setting at 1/200 sec shutter speed
Use direct flash off camera Aperature Priority (Av) setting at 1/200 sec shutter speed
Use flash fill Aperture Priority Auto shutter speed
Use flash with modifier (Bounce card, bank or ceiling) Aperature Priority (Av) setting at 1/200 sec shutter speed. Set the E-TTL II meter to Average.  Release the flash head from the straight ahead position so that the distance calculation is not used in the metering.

Label your best result from each of the 4 techniques, write down your camera settings for each photograph and post them separately.

Read the two pages (posted  in the Lesson 9 section) from the Canon 580EXII or the Canon 600EX manual to help understand what the settings mean

Instructions for using Canon Speedlite 580EX

 Instructions for using Canon Speedlite 600EX-RT

Assignment 8 Outdoor Flash

1. Make a portrait where the person’s face and the background are the same exposure.

2. Make a portrait where the person’s face is exposed one stop under and the background is normally exposed.  Drop the power of the strobe by one stop keeping the f stop the same.

3. Make a portrait where the person’s face is normally exposed and the background is one stop under.

4. Make a portrait where the person’s face is normally exposed and the background is two stops under.

All four should be photographed in exactly the same place to make it earier to compare the results.

This is a test for your reference and should be laid out accordingly.

Print your f stop and shutter speeds.

Subject should be 2 or 3 stops darker than background.
