Thanks everybody.
My setup? Well, it was 10 am so the sun was behind me and pretty bright. The wasn't a cloud in the sky. I had my flash on a light stand, opposite the sun (if the sun was behind me and on my left, my flash was on my right). I had my shutter speed at 1/125, which I realize now should have been faster. I did have my flash on manual, but I need tips (using small words
)for metering this type of set up.
