I have a Canon 70d and I use the 622c wireless trigger/remote with the YN 565 EX flashes. When setting them on E-TTL, all my shots are overexposed. I've checked the camera and the flashes and all the settings are normal. Using direct flash, not bounced off anything.
I've fixed the problem by setting the flash to -3ev exposure compensation but I feel this shouldn't be needed.
Any ideas what could be happening?
I tried using the flash on-camera. I have a 60d and 70d, and with both I needed to set my flash to -3eV to get the right exposure.
