Friday the 13th.

..is not a bad day so far. I am shooting an event tonight; first, some more writing (the Travel Photography book: I am making good progress and I trust I will have it finished before Xmas), and some admin.

A quick note, today, about TTL flash. You can of course set up a studio setup with manual flash, and when you have time, you do that. But when you do not have time, use TTL for off camera flash. Remember:

  • Use flash exposure compensation when needed (when the camera decides to over- or under-expose the shot).
  • Avoid reflections.
  • Meter off something mid grey.
  • Disable your on camera flash (so that it sends commands, nothing more).
  • If you have two flashes, set them to “A” and “B”.

Now set ratios between groups (Canon) or adjust groups to taste one by one, by stops (Nikon).

I had two flashes here: main flash A on the left; hairlight B on the right.

A:B = 1:1 (Canon) or A and B both set to 0 FEC (Nikon):

A:B 8:1 (Canon) or B -3 stops FEC (Nikon)

A:B 1:8, or A -3 stops FEC (Nikon):

Although the way of setting them differs a little (ratios vs per-group adjustments), the end result is the same. And the benefit of using TTL for this is that it is very fast. TTL with some knowledge and some adjustments when needed, and Bob’s your uncle. Try it, if you have several flashes.
