Hi... Im just starting out using flash so I bought a 2nd hand 420ex here to play around. I'm confused. I give a scenario and hope the more senior bros can help me.
Manual setting: 1/100, f3.5, iso 100
without flash : dark
camera flash: exposure is correct
external flash: dark
Why do I get dark pics with external flash? is the flash spoilt?
i left the flash setting to high-speed sync and off the high-speed sync both get the same results. Any bros can help me?
