Highlights of Canon ETTL

Thursday, 2.8.18

Canon ETTL workshop is about working with a Canon Flash and its features to be able to handle unexpected situations in weather and lighting.

Increase the Recycle Time to get more batteries space.

  1. ETTL Flash always sees what the lens sees
  2. The telephoto and ultra-wide angle lenses are used for close-up
  3. “any aperture” flash operation
  4. Flash metering and ambient lighting metering combinations
  5. Speedlites
  6. Recycling time involves decreasing distance to the subject
  7. Wider lens aperture
  8. Higher ISO
  9. Fresh batteries
  10. External battery pack—580 EXII/600 EX-RT II

A quick flash feature: the subject should be close, and then take the picture when the light is green.

Illuminate before 100% ready. If using full power, then wait for “After” the red light.

External Speedlite Control

ETTL is automatic

Flash Zoom

Shutter Sync

Flash Exposure Compensation, from darker to brighter, in which the darker it is the number increases on the negative side. And, the brighter it is the number increases on the positive side.

Shutter speed is for light and movement control. With a flash, the shutter speed controls the ambient light by dragging your shutter.

For example, 200/sec is normal, while 60/sec is controlled light.

The aperture decreasing from f/16 to f/8 is similar to the ISO 100 decreasing to ISO 400. The decreasing creates more distance and brighter of the subject.

The nearest distance is 3 feet. Expose the subject at one distance.

The color of the flash is orange CTO, which looks like a warm and healthy glow.

E-TTL II is better than the E-TTL, but they both have the same sensor. Its focus is on what is the closest and brightest.

Flash Exposure Compensation

  1. +1.3 Stops adds 1 Stop light and improves subject
  2. -1 and -2 Stops to add gray to the bright subject.

Exposure Composure changes background. 3 Stops darkens bright background so that the subject blends with the background. You can blue the background so that the subject stands out better. Use a High Speed Sync. You can also use Freeze Action.

Flash Exposure Lock—involves using “frame,” press the asterick, and reframe.

Multimode is the multiple pops of flash, which creates interesting effects for creative people.

When your flash is overheated, it will freeze during Phase I, in which you shouldn’t take too much pictures so that your flash won’t get overheated and freeze. You can also increase ISO and decrease aperture when you want to take a lot of pictures.

The camera will always override the flash. If you use flash control, it will take priority.

Consider ENELOOP rechargeable batteries or the ENELOOP Charger.
