Heya LahLahSr thanks for the interest, i usually do those kind of test during the bad weather days and since spring is taking a while to take off here there is plenty of occasion.
first and second pics i had a clear bowl of water siting on a CD the one with the silver coating is more reflective, on the second pic i got a bit lucky i think, a droplet collided with another coming out of the water impact.
if you plan to have fun doing this i advise you to put a clear UV filter because youll have water all over your lens hehe.
yesturday i tried a new technique with a flat glass and a CD under to make a water ripple crown but i didnt get any cool results, its a bit touchy with the lights angles to get the best results possible.
here is an exemple of what i mean by a water ripple crown, this one im using a normal surface.
thats the best i could do to explain what i did considering my first language is french, so happy testing and if you plan to do a few test i cant wait to see your results.
