thank you for the comments everyone,
for cropping - i take your point, the ripples arent centred, looks a bit odd, i think i could actually get closer to the drop, was just worried about water splashing on my expensive glass, would i be right in thinking the odd little bit does not do any harm? i will have to look up some colour correction stuff, not sure how that is done, but shall have a read this evening,
for the flash off to the side (yeay i get to use both the 603s and the canon shutter release) is an acceptable starting point whatever ettl tells me to use and about the same distance from the drop?
ps i was doing this in a conservatory, all windows, the roof is thick clear plastic, it seems to be it is good light without direct sunlight, no strong shadows,
should i try to get as close to iso 100 as i can while keeping the shutter speed to 1/125?
that one was shot at f25 iso 400
any thanks again for all the comments after a long nasty day at work it is a nice thing to come home to
