Hi Rich...

Now those are hard shots to take if you are trying it manually. I would suggest a short depth of field, (Low F-stop) and a fast exposure. I would also do it totally in Manual. I would focus on the bottom of the berry and just adjust the tripod, so the frame is lower. I would not tilt it, becase that would throw off the focus. I would just lower it.

If you had a optical trigger then it would be pretty easy. Manually on the other had... just get a constant water flow so the drops fall regularly and "wing it".

Looking good so far! keep us posted and let us know how you finally accomplish it.
