general rules for dialling in Flash exposure compensation in ETTL
if the background is brighter than the subject dial in + EC the amount depends on how much brighter the background is so you need a bit of trial and error start at +1 and work from that.
this is out doors bright sun etc
if the background is darker than the subject dial in - EC same as about the amount depends on how much darker the back ground is again start at -1
this is indoors in shade at night etc
don't leave the flash just in ETTL it will rarely balance correctly you need to practice balancing the ambient exposure with the flash exposure.
another general rule is expose for the background and use the flash EC to correct the exposure of the subject
hope that helps a bit
It does, but I have a jillion flash questions.
Without a flash, I am predominantly an aperture priority guy. With a flash, I keep hearing two schools of thought on flash settings when you don't have time to dial everything in:
- Rookie mode: Stick with whatever mode you usually use without a flash, use your knowledge of that mode to nail the ambient and heavily rely on tweaking FEC as you go.
- Let's get braver mode: Switch to M, guess/practice at average starting settings (before the shoot), say ISO 200, F/6.3, Shutter 1/80s, and then tweak as needed throughout the event, using the rule that shutter affects ambient exposure and aperture affects flash exposure. If either aperture or shutter are getting forced into values you that are problematic (shutter too slow to hold, shutter too fast for sync, or an aperture that is composition unfriendly to keep shutter where you want it, etc.), tweak your ISO to bring you back into settings that give you elbow room either way for flash and ambient exposure.
- Jedi Event Master Flash mode: Bend the spoon with your mind. Just instinctively know what to do.
The concern with events is uneven lighting, which makes locking in 'you're good, just shoot' settings next to impossible. Can someone give me a simple algorithm for managing this?
Also, I understand the hit to power by using HSS, but sometimes you have
to use it, right?
