I usually have the exposure mode on my cameras set to “Manual”.
Likewise when I use my strobes, Speedlites or flash units.
That doesn’t mean I fight the technology especially when the results are consistent and predictable.
It’s always a good idea to learn how to work the Speedlites on power ratio or manual settings just in case E-TTL or iTTL goes berserk and no matter what you try, it’s unpredictable.
For this particular picture of Jodi Newton, I used Canon’s ST-E3-RT transmitter with the new Canon 600EX-RT Speedlites.
The Thought Process
I had 30 minutes and was running late.
So not having to figure exposure manually was a godsend.
I tend to start with the lowest ISO and meter a scene.
In this case, the light levels were extremely low, it was something absurd like 1/8 sec @ f4 ISO 100.
I knew from my own experience that 1/8 sec was not something I could successfully hand hold.
So increasing my ISO from 100 to 400 allowed me to confidently use 1/30sec with a 50mm lens on my Canon 5D Mark II.
Once I made some exposures with that setting and verified light over the pool table was going to be visible, it was time to bring in the Speedlites which I had set up as Group A (Keylight) in Photoflex soft box and Group B (backlight) fitted with Honl grid to control spill.
With the STE-3-RT attached to my hotshoe, dialing in the ratio A:B was a cinch.
