Thanks for the feedback, as for settings on the camera... I am using a canon 40d, shutter sped at 250, i think I had iso at 0 in these because I decided to use flash, just experimented with the angles until I got no reflection, and I was in shutter priority (I think Tv on canon cameras??) so the aperature was preset, although you could definitely experiment. I have it manually focused on the water surface where I drop the food, and I drop the food at about the same time I am pressing the shutter button because they are much faster at reacting than I am. I think this is the whole procedure I use...
