hi,
what do you think of having the strobe directly above the camera to have a top frontal lighting so as to get a more even lighting for the first pic??
for the 2nd pic....it is unusual but i kinda like it....cept that if u did not mentioned in your post that it is a jetty topside, i can't really make out what it is....the effect of the "fake" ray to me is like the fishes just came out from some ufo.....very interesting.....
for the 3rd pic......maybe u can move closer to the jetty and light up the other half in the water with your strobe......the bottom half on my screen looks pretty dark to me...of cos the bikini babes would bring home the trophy....
