Not the best pics but the best of a bad bunch, considering it was pouring out of the heavens,
Dark and only the built in camera flash to work with,
First time taking pics of a gig,
I think most of them were taken at 1/60
Nice set of pictures. You were obviously up against the elements. Just a few comments (not criticisms)
Focus 1 & 3 are not too bad, #2 is a bit out of focus.
The flash overpowered the stage lighting in #1 but theres a nice balance in 2+3
In all 3 shots the mic is blocking christies lovely face, they seem to be taken from the same position, you should consider where you are taking the picture from, are you in the best position to capture the image?
Using flash at a gig is a complete no no. Try to shout without flash. Try using a F2.4 lens and iso 800-1600. That way you will reserve the mood from the stage lighting. Also set you meter to spot.
