Lesson 8 Dedicated Flash

Assignment 8 Dedicated Flash Canon System

Use direct flash on camera Priority setting
Use direct flash off camera Priority setting
Use flash fill Aperture Priority
Use flash with modifier (Bounce card, bank or ceiling) Priority setting.

Layout your best result from each of the 4 techniques, write down your camera settings for each photograph and post as a single entry.

Read the two pages from the Canon 580EXII manual to help understand what the settings mean





For the first 3 parts of the demonstation, the ISO was set at a 100. Notice the change of f stop on the two Aperture Priority examples. I didn't adjust the images in any way so you can see just how well the Canon Flash metering works.





The pictures below were all shot at ISO 100, off-camera and set on Priority. No adjustments in post.

Lesson 7 Strobe Outdoors

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. Turn the stobe power down one stop and keep the same exposure as the 1st photograph.

3. Make a portrait where the person’s face is normally exposed and the background is one stop under. Don't forget to turn the strobe back up one stop to match the 1st photograph.

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 and you will need to adjust the strobe for the second shot only.

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

Print your f stop and shutter speed under each photograph.

Subject should be 3 stops darker than background.

Lesson 6 Strobe and Tungsten

The photograph above is an example of how I used strobe and tungsten in my work in the 1980's.

The background was lite with tungsten light and the subject was lite with a fresnel strobe with an Roscoe 3411 conversion gel making it essentially a tungsten balanced strobe. The camera was set to tungsten color balance. The 1st step was to figure out an exposure that would give us the most beneficial shutter speed while considering the maxium possible aperature for the lens being used. The 2nd step was to adjust the power setting of the strobe to match the f-stop. The use of the shutter speed/f-stop slider helps to visualize the exposure relationships. Care was taken to keep the lights confined to their intended targets and a capture of each light was made separately to confirm its purity.

Lesson 5 Size Matters

Assignment 5 Take 2 portraits of a person one with a large softbox or Octobank and one with a smaller light source like the beauty dish or Quantum 12" square softbox. Get the same results for each light by placement of the subject and the background. Look at the results of the demo for ideas.
