I attepted to do water droplet shots. I had the macro 180mm lense and the extention tube on a tripod and a clear dish half full with water with a white sheet of paper behind it. I filled a bag with water and poked a pin hole in but I then realised I had no way of keeping the bag above the dish. I thought about getting someone to hold it ( obviously the droplets would move slightly but I could havelived with that as am experement. There was noone in however and I coldnt take the photo at the same time. I'm going to try this again when there is someone to help me. I might try this in the studio as well to get different lighting.
